So if the sun becomes a red giant we all know that Sedna will live
NO IT WON'T BE SEDNA. in 5 MILLION years PACK YOUR BAGS FOR SATRUN

i think we should pay it a visit
Killswitch ali Right? Like why the fuck not lol possibly the strangest thing that's actually somewhat close and we just like nah we good .
Stuff costs money... a shitload of money. More money that you can envision. If you ever ask why don't we... The answer is money.
It is pretty pointless actually.
Yeah lets forget about the lead contaminated water in flint, and many other places in america, and instead invest the money in something like this.
580player No. How about America stops using an absurd amount of money on Military and instead use more of their budget On NASA and fixing issues in the country too.
Sedna will be surprised how far the Apes have progressed, we were throwing flint spears on her last visit, we now have the technology to pay her a visit .We definitely should hop over we may not be around the next time our paths cross .
This timeline of human prehistory comprises the time from the first appearance of Homo .... 13,000-11,000 years ago (11,000 BC to 9,000 BC)? I thought he said it takes 11 thousand years to orbit
Lord of the Pies It depends a bit on what you refer to exactly. If you mean Homo as in the genus Homo, then it appeared roughly 2 million years ago with the emergence of Homo habilis (as of yet it's believed Homo habilis was the first species in the genus, although that is of course subject to change, just like how we used to think Homo erectus was the first species in the genus, until remains of Homo habilis were discovered).
If you are referring to Homo sapiens (anatomically modern humans aka our species) then it would be somewhere between 500.000 and 300.000 years ago they (or we) came into existence.
So Sedna has done a few laps around the Sun during the existence of both Homo and Homo sapiens.
But other than that you are quite right: the last time she paid us a visit we were indeed using flint based tools. It is quite amazing to think how far we have progressed in the time it took Sedna to orbit the Sun just once:)
When Sedna is close to the sun, the sun's gravity repels it out into space and when it's furthest away from the sun, the faint gravitational push from the nearest stars and planet system pushes it right back toward our sun and that's why it has the orbit it has. Last time it visited, human beings were so advanced, they harnessed Tesla technology through the pyramids, but then a polar shift reoriented the Earth and wiped out the civilizations. Anyway, people need to buy up my "Impact" and "Dance of Death" James Grider novels on Amazon so I can afford a used car.
@@Khenfu_Cake Actually we (well some of us anyway) had copper, lead, gold and such soft metals back then.
@Chuck Finley Well yes but you'll probably be surprised to know that initially the main trade good was actually certain stones and the metals were mainly used for decorations and special tools like copper water purifying pots or lead sling bullets. Even gold was mostly used for so called Baghdad batteries more than it was traded to start with....Currency really only started a bit later after a couple thousand years.
i feel like such a nerd being so excited about this
Next Gen Gamers you are not a nerd, this stuff is so awesome.
96serpendity youarelostnotme thank you😀
Next Gen Gamers your welcome😊
Haha yeah me too🤓
Next Gen Gamers I'm excited about it, too. No shame in that.
I had a dog named Sedna a malamute or effectively an Inuit dog. She died of a brain tumour in 2018. I'm going to have a small fragment of her ashes kept for the future when space travel is common and hope that one of my distant descendants can have that fragment scattered on Sedna. Maybe a little dumb but it'll make me very happy to know Sedna is on Sedna.
Maybe one day when humans themselves can travel in spaceships at a quarter of the speed of light and can get to Sedna , then a part of Sedna could possibly be a part of Sedna when all humans (and dogs) currently alive are long gone figment of the imagination.
This giving a dog named Sedna is the equivalent to Disney naming The yellow gold dog Pluto after the planet in 1930. Over 90+ years ago.
It's not dumb it's beautiful you should do it at least then some part of your little baby will live on among the stars long after everything else is gone ❤❤❤❤❤❤❤❤
Its ok, Pluto, you will always be the 9th planet to me
Agreed.
There conditions of clearing ones orbit to be a planet is absolute arbitrary hogwash
Agree
Get over it already. You're more obsessed about this than those crazy exes in those crime documentaries lmao.
Crazy to think at such a huge distance the sun still has a gravitational pull on it (for my simple mind)
2:45
Sun: haha I got this planet!
Senda’s birth parent star: Senda!
Senda: Help!
It's Sedna.
@@MeIsOnu no, just 5 and a half light hours.
Hehehhehehehe
@@MeIsOnu sedna does not reach a light year from the sun even at aphelion
I think we should pay it a visit! This is a great opportunity to find out what kind of impact such a long orbit has on a planet. This is a real visitor from outer space! Let's not miss it. I saw many people complaining about money..well, we did send Voyagers way back in the '70s, and today, they are about 139 AU away from us...So for a spacecraft launched some time during 2060, reaching 80 AU is perfectly doable, if you ask me!
Abhishek Sanyal I agree there is no limit when it comes to science
Oh yeah let's post that on RUclips hoping NASA to read.
It would be interesting, but the priority right now is to understand where life came from, and mars is a very popular candidate due to it's past. And when you think what we'll need in the future, we'd be looking for a new planet to live on. Essentially, doing a mission on Sedna would just be a waste of time and resources.
while this time frame is an incredible opportunity, the cost of this mission in our degrading economies is somewhat compromising. I mean, if the mission has to be planned, it is now : designing the rockets, the modules, building it, would take several years, if not decades partially due to funding limitations.
If I was an astronomer I would use a gravity assist from Jupiter and Saturn when this object is that is perihelion and there are probably dumbasses to do it when Santa is about to leave the solar system again and they're Psychopaths who want to go to the goblin or the forgotten one ....... (2014fe72)and voyager 1 and 2 ARENT EVEN ON THE RIGHT PLANE! so Voyager 3 or 4 and 5 6 7 8 9 10-
that really is an untinkable distance.
hahahah

Thanks making a video about my favorite dwarf planet!
No problem i guess
Dreksler It's not the farthest Dwarf planet Orcus is (Also Sedna Is a Dwarf planet candidate even Orcus)
Miguel, that is so not true, Orcus at it's aphelion is 48 AU, while Sedna at it's aphelion is 936 AU. Making Sedna almost 20 times more distant from the sun than Orcus. Also Orucs has at least half the diameter of Sedna, so it may not even be spherical let alone a dwarf planet. Check your facts before correcting anyone.
Dreksler
Hey human,i am Sedna
Sedna good . planetbro wear a sweeter and muffler
I think its an unbeatable mission. The materials that Sedna has been through in its lifetime as well as the nature of matter relating to mater closer to the sun would make for seeing this dwarf planet an absolute must. It might, incidentally, be a an excellent candidate for a biological time capsule of all species on Earth, in case even the outer solar system, esp, gets fried, crushed, or disbanded. Think of it also as a true jumping-off point for deep space exploration. ALSO-- if we plan for it now, I for one might actually be alive just long enough to see it! Who, of course, wants to wait another 11,000 years?
Oh man, visiting Sedna is not an opportunity that should not be missed, who knows what discoveries are waiting to be discovered.
i don't think NASA would do it seeing that they cut their budget like every year
Dreksler
I'm with you on that. Considering the speculation it could have come from another star system makes me wonder if life had a chance to develop there before being ejected (probably due to unstable orbits from gas giants).
Or even more out there, a highly advanced civilization had to move planet to avoid a supernova...I could go on, I'll stop now :)
Evol Bob A highly advanced civ. could perhaps keep their planet habitable at such distances, so there could be life then. We would probably have noticed them by now though.
Justin Higner yeah
1:02 worst nightmare of a flat earther
Hahahaha! Nah, man!! The worst nightmare of a flattard is going to school, especially to science class!
Made my day.
When Sedna is at shortest distance to the Sun, I would be 70-71 years old
@pjd412 Born too late to explore the new world, born too early to explore space but born just in time to experience WW3
I will be 79
I will be in my 80s or 70s
I will be 80-81 year's old.
I would be 65-66 years old
Think about this. The only reason we able to find Sedna was because it’s at its closest in its orbit. There are probably other dwarf planets with similar orbits that we can’t see because they’re too far away.
It's insane how far reaching the gravity of the sun is
Can you imagine how lonely Sedna must be? Kinda makes me sad
Today is the first time I watched a video of yours, and I'm hooked- they're all so informative, interesting and well presented in an organized manner. Please keep making videos!
i love your video and i want to be astronaut
I just wish we could all get along, stop these pointless wars, and focus on space, advancing our technology, and have bases on other planets and moons, and one day, we could go out onto another star system light years away. Our true enemy that's slowing us down is money and governments. A lunar base is actually something we would need if we do want to test out newer prototypes of space crafts and rockets! 😀 Today, there's no lunar bases on the Moon, but if we could come up with ideas of how to get one, then it's a possibility! Or wait until someone else does it in the future 😒
+Dreksler I love all your videos man. The content is very well organised and put together in a way that it makes most sense. I saw a lot of people commenting on the background music you use, calling it creepy, but I think the music you use syncs perfectly with the content and makes the video that much more better. Keep up the good work, subscribed !
hey great content. hoping to see a video on the 9th planet which is possibly affecting sedna's orbit.
Bashir Khan Thanks man, i would make a video about the ninth planet, it's just that we haven't seen it yet. When we spot it i will make a video about it. Thanks for watching!
Bashir Khan
*having young Sedna flashbacks with Planet Nine affecting the orbit*
Nibiru!....forget it, the lizard people will not allow it!!!
What I don't get is we have discovered other solar systems Light Years Away yet we still don't know if their is a planet 9.
That's because the way we detect planets around other stars is by either measuring a slight wobble around a star, which would only be detectable for massive planets close to the star, or by measuring the dimming of a star as a planet passes in front of it. We could detect planet X this way if we were to send a telescope beyond its orbit and wait for it to pass in front of the sun, hoping we're positioned at the right angle to observe this, then wait thousands of years for it to make another pass, then a 3rd pass to verify its existence.
DiamondAviation planets dont glow
But they reflect light...
Not all planet reflect light at the same brightness. Maybe it's too dark than anything else ever discovered. Just like the darkest exo-planet ever discovered called TrES-2b, it's a Jupiter-size planet but it only reflects less than 1% of light that falls on it.
These planets have small effects on their parent stars, either gravitational or visual, that is detectable. You could detect a fly buzzing around a light source easier than a fly in the dark, even if the first is much much further away compared to the second.
Dreksler: sedna is the furthest dwarf planet in the solar system
Leleākūhonua: you forgot someone...
2014 FE72: ...
"Eart"
How could anyone not want to go to Sedna???! A dwarf planet from a potentially different planetary system that won't be reachable for aeons longer than the existence of civilisation.
Wow, how did I not know about this planet before? Subscribed!
Thanks!
i first heard about it when i was in 1st grade... about 12 years ago
Jake Lover dwarf planet
How did I go so long without running across your channel? All top notch and interesting.
Thanks!
I am very amazed to hear talking about extra solar planets & see how difficult it is to get a good image of a planetoïd in our own solar system ...
we can't even get images of planets from other solar systems. So what's your point?
Lars Shawlan bruh you’re acting childish, the point is obvious, go step on someone else’s gown.
nice video, keep the good work
"Sedna is the most distant object in our solar system" well that aged like milk. Looking at you, TG387.

Thanks a lot for another great video. I have learnt something new today.
2:45 Stole the pla...
Well the sun being naughty i see...
Crazy how he said we don’t know what Sedna looks like in our solar system but we got a picture of a black hole millions of light years away..also a planet that looks like earth
and your point drum 🥁 roll brrrrrrrrrrr what's your point interesting hmmmn
we should send at least a space telescope in orbit of say neptune to get a better look at sedna. if it were captured from another star than sedna may be the closest thing to an exoplanet we can maybe explore one day. imagine what we might find there.
I wish I had a teacher like you. Not beacause you teach teach astronomy, but because you teach very nicely and I understand everything
I TOTALLY Love All Planets in Our Galaxy!
I love your videos and your voice is really soothing n cute. I love your accent. I could binge watch your content all day long.
Can't stop watching all your videos!
Who else is just awed by the sheer gravitational power of our sun
It's a big boy/girl.
Absolutely fascinating.
Formerly most distant. "The Goblin" announced Oct 2018 gets much further away.
Holy shit, thanks for the info!
Indeed. The orbital semi-major axis of the Goblin is larger than that of both 2012 VP113 and Sedna, meaning it travels much farther from the sun along its orbit than they do. At its most distant point, it is an incredible 2,300 AU from the sun.!
0:21 why is it funny how he says 'we dont know'
tfw I'll probably be dead by the time Sedna gets the closest to the sun.
I hope we can send probes, similar to New Horizons, to take pictures of all the Kuiper Belt dwarf planets especially Eris since it's even slightly larger than Pluto. Sedna is also a very peculiar dwarf planet due to it's very far distance and cery large elongated orbit.
Pluto is larger than Eris.
I don't understand how the sun's gravity can affect it at its aphelion. It's so far out it doesn't seem gravity could touch it at that distance.
Gravity has infinite reach. Sedna is still much closer to the sun than any other star at aphelion, so it still orbits.
Because the sun is millions of times larger and has millions times more powerful gravity
I don't knw how many times I have seen this video. Sedna is soo fascinating!!!
Imagins millions of years later in a distant solar system, someone will upload a video to a video sharing platform about Earth, the most distant planet stole by their Sun
Maybe Earth was already stolen and brought here by our own sun.
Even our own solar system is mind blowing
Absolutely crazy that the biggest black hole can engulf the entire orbit of this dwarf planet 4 times over and still have 30b km to spare..
It's getting to be summer on Sedna. Young Sednites are said to be frantically working out to get that "beach body ready."
Imagine if we get there in 2075, and discover remnants of a spacecraft, millions of years old, that came from Earth. From another intelligent species that came before us. But that would be just to good to be true.
These dwarf planets are so fascinating! I wish we could get to these world's faster so we can study them. It does amaze me how small world's can exist so far away from the sun...
great video verry nice tuturial
Ur vids are awesome keep going
Serbia! I was trying to place that Slavic accent.
EART!!!
Subbed
Thanks!
Me three 😎
Dubbed
JanetFunkYeah Manga
I subbed as well.
Very nice video my friend.
Grabe sobrang layo ng sedna haha nkaka amaze.
By the time Sedna is at its closest distance to the sun, I'll be in my early 70s. At least it's possible for me to live on to see it, I hope I won't die before it. But the thing is, both of my parents will be dead by the time Sedna is at its closest :(
I will also be on my early 70s & hope not to die, but yes, my parents will also be dead at the time Sedna is at shortest distance
Same. I'd rather die
I'll be in my early 80s
It would be a great loss for humanity not to have a probe around Sedna . It would gave a tremendous amount of informations about the outer solar system .
At least some info would be something. Now that the planet is so close to say . :) 2075 is not so far în the future .
Good knowledge
We need to visit Sedna
The question is...how do they know it’s orbit, if we never witness it before since it takes over 11,000 years to finish an orbit?
Elena Garcia Everything orbiting the Sun follows what are known as Kepler’s Laws... if you’ve know a few things about a body such as its mass and current distance/speed you can figure out its whole orbit easy enough.
Just imagine sending probes to Sedna on this approach, and have them gather information about outer space with photographs and all, and then collect it all 11,000 years later!
So so far away..And still it just in "the neighbourhood." Someday, maybe someday we can send a craft there. But thats probally in a far future..Incredible fascintaing still.
You r awesome video maker
Sedna is the goddess of the sea and marine animals in Inuit mythology.
I think that the sun just looks like a really bright star on sedna
the goblin has a 2 times longer orbit
I think it's time we start to review how we're teaching kids in school about the different bodies different objects around the solar system
5 days to reach light= incomprehensible distance. Yet we use light years. So imagine how far the closest star(besides sun) is far away from us: 4.2 light years. And then imagine what it is when scientists use billions of light years when scaling universe lol
to think from sun to the earth it takes about 8 minutes, so if the sun went out, you wouldnt know for 5 earth days on sedna
If only I had Goku superpowers and be able to go anywhere in outer space in the Universe.
SS God lol
Super S God IKR
And get lost unable to get back
Sedna.....aaaaaahhhhh reminds me of Warframe.
You're gonna be big, man.
If we don't pay a visit the set and at this century will have to wait another 12000 years
Thank you for the video. It is hard to find information on Sedna on in Internet
This is the first video i have ever watched
Prove it
Just like a chihuahua is still a dog, Pluto will always be planet number nine
Good job!
We should send a probe there. Sedna is really neat.
nice video
Sound at 0:57 seems so pleasent and nostalgic to me
When it comes to this theoretical "planet nine" that keeps getting mentioned I have one question : if there truly is a gas giant orbiting the sun out that far would it still be classified as a "planet"? A major part of the "dwarf planet" classification (which is what Pluto was downgraded to) is that a regular planet has a clear orbital path whereas a dwarf planet does not. Dwarf planets go through belts of asteroids and debris and their size is really more of a scientific afterthought. So if this planet nine exists out beyond Sedna that would place it within the Kuiper Belt at its closest and at it's farthest all the way out in the Oort Cloud. Therefore it would not have the clear orbit required for a planet classification. And even if it is so big that it's able to clear out a path under the power of its own gravity it's so far away and would take so long to circle the sun that comets and other debris would have more than enough time to float back in and refill the area that the "planet" had traveled through.
Nice video
Maybe in the future we could build a base there as a refueling station for our warp drives or have a permanent base there
This must be So Cold!
Fun fact: Sedna takes 11,000 years to orbit the sun!
Hi Dreksler!
Question: Doesn't it stand to reason, that if Sedna's orbit takes 11.000 years, that there may be several other dwarf planets, perhaps many more, that are either smaller than Sedna with even greater orbits but that we just don't see most of them because the majority of them are orbiting too far from Earth at the moment?
I'm not Dreksler, but I think you are right. This video was posted in 2017. Since then scientists have discovered several more objects like Sedna. The most distant is probably the one nicknamed "the Goblin" which appears to have a 30 000 year orbit; theree times as much as Sedna's. And yes, we can only detect these objects when they are reasonably close to the sun. So how many more objects are out there, currently too faint to see? Most likely a considerable amount.
holy shit theres an object that takes 30 THOUSAND years to orbit???
Scottie, how long to fix the Warp Drive?
I bet it's warm and volcanic
Inaccurate the sun is so far from sedna that there would be no daylight ever
All I knew about Sedna before I got here was that it's cold and full of Grineer.
we just aren't going to make it out there at least not for thousands of years
Not with that attitude..
polifatts or with politics.
+Trey Stephens Well at least NASA is getting a good amount of funding once again. President Trump just signed a bill into effect which granted NASA the most money it has received in decades.
polifatts it's too bad they won't let me in space.
polifatts to bad trump is to much of a fucking moron
Even if Sedna was at its furthest, some black holes would still be inside it
WOW the jump off date would be in twenty years! We should build a probe!
Man, makes me wanna be an astronaut. Like... what's really out there.. yolo... how could I not want to get in a rocket ship and go so beyond..
I knew this planet's name. I did not know how far away it is. I thought it was just a few miles from Pluto. I stand corrected.
