5:45 The unit for surface gravity cited here is faulty. Its surface gravity is 8.27cgs, not 8.27gs. This is in contrast to Earth's 2.992cgs (log_10 of 980cm/s^2), making the surface gravity of Gliese 440 5.278 powers of 10 greater than Earth's, or 190000 times Earth's surface gravity (which fits nicely with its mass being about that amount as Earth's, and its radius being comparable).

Most of these stars, though relatively near, are invisible to the naked eye. It helps one understand how dark, cold, and probably lifeless most of the galaxy really is.
The perfect combination for falling asleep: a soothing voice and interesting facts. I was well-informed before unconsciousness overwhelmed me. (Woke up suddenly at the music at the end tho)
Yes, please continue. Nearby stars have always been a fascination for me, since I was a young teenager. (now almost 60) Its too bad that there is little information out there on so many, one would think they would be just as important as the ones much closer by, as twenty+ light years isn't that much further out.
Marble coloured Nick, Marble, Your Black hole does wonderful Artwork too. You should start selling it when Hawking Radiation allows. Thank you. Love jeremy.
Nice series..., only complaint is the audio being toooooo low! If YT decides to interject a commercial break (WICH ARE WAY LOUDER!!!) 🤯😵😵💫..., I don't dare to think about the amount of complaining (and revenge) my neighbour(s) when the audio suddenly JUMPS.... So please fix the audio 🙏. The video deserves it, because everything else is 👍👍👍. Greetings bibia 👋 (who left a like non the less 😉..., naturally!)
New goal: become an astronomer so I can discover stars and give them passable but fake star names. "Oh, that's Phaplodides. I discovered it last week."
@@parallaxnick637 I was thinking a 3D, rotatable map. With the ability to filter results and yes, hyper linked to a database of information. Not trying to be critical here. The existing map is beautiful as is. Just wistful thinking. If I had the time and ability, I'd create it myself.
My local astronomy club sells “you are here” shirts with an arrow pointing to an arm of the Milky Way. I can’t remember my geography but I know where to find my home planet so I should be ok as long as I know where my towel is. 👍🏽
It occurred to me the other day that "Dune" and "Forbidden Planet" share a common concept. I'm no Dune expert, but my understanding is that the planet Arrakis orbits Canopus, a star much brighter and hotter than the sun. While the planet is mostly an inhospitable desert, the one city on Arrakis is located near the planet's north pole in order to avoid the worst of the heat. Now to Altair 4: Listen to the landing coordinates given to the Commander by Morbius. They are within a few degrees of the planet's north pole. The rest of the planet appears to be a desert. Altair is a brighter and hotter star than the sun. Coincidence? Maybe. Maybe both Herbert and the story writer of Forbidden Planet knew some astronomy.
How about we all like each others' comments (till our thumbs near fall off) and collectively give this channel a boost. Would that work ? The succinct research, the passion and the humour is worth a bucket-full of promotion and 38,000 cramped - but happy - thumbs ? Nick has supplied the yacht, but its for us to hoist the sail's.
It is interesting to know more of the neighborhood and concretely get the impressions of how many red dwarves, and brown dwarves, and truly rogue planets are around. Seems like the neighborhood is well reviewed. Can you give a rate-of-discovery review? Is the curve still climbing or dwindling off like most have been found? There's a lot of space out there.
In terms of stars, there are very few likely left to be found, but they are still being found. Lood at Teegarden's Star. Brown dwarfs and rogue planets are likely still at the beginning stages.
Because to become a neutron star or black hole your final mass has to exceed the Chandrasekhar limit, which is 1.4 solar masses, or 2.5 times 141's mass.
What would cooked pasta in a 100° brown dwarf look like? That thought led me to something else I'm pondering. Do people in the UK set their oven temps in Celsius? Don't mind me. Its late. I don't get out much and this is the only quiet time of the day I get.
Brown dwarf is definitely a misnomer, as they would be a dull red. Just look at the colors of Titanium being heated to red hot at 1000 K it turns a visible red. Nothing is brown hot, same reason there are no green stars viewed outside the Earth's atmosphere. Stellar color is from the temperature of the star with O stars being the hottest and the M stars being the coolest. Stars are classified from O, B, A, F, G and K. Yes quite the illogical way to line up stars by their temp/color spectrum.
Great stuff. I do have a problem when the standards for comparison change, eg size of the sun vs alpha centauri. I can understand why AU vs parsecs, meters vs kilometers, would be used, but at times I would just like # solar masses, # au for everything. On the other hand, for some strange reason it does help when you compare planetary orbits to earth, jupiter, nepture orbits. So I am not that consistent myself. Maybe a little reminder conversion chart would be helpful. Keep up the good work.
The reason I use Proxima centauri as a benchmark for red dwarfs is that red dwarfs are so ridulously small compared to the Sun that the differences don't register.
I can't hear Sigma Draconis without thinking of it's presence in Star Trek lore. Of course, the episode was so bad, it does not deserve a mention by name.
Question: If an F-Type star can have only 99% a solar mass and be 1.04 times the radius, then how could it be hotter and live so much shorter than our sun?
I had to delve deep for this. I contacted my backup brain (an astronomy forum I belong to) and they eventually concluded that stellar ages are notoriously difficult to pinpoint, and that Zeta Tucanae is probably much older than presumed, and thus moving off the main sequence.
Great video! You are making these movies in less time. Thank you we will watch them when you put them out. Click like and subscribe. This channel is awesome.
Since astronomers took a whack at redefining the Ancient Greek term "planete" which means. "wanderer" (against a fixed background of the stars), could you please dive into the technical definition of a star? How has the definition changed over time? If a star is defined as a mass with sustained fusion, where does that leave quark stars? Or zombie stars? Would a Population III brown dwarf mass object have been a star?
that's a can of worms. I believe the official definition of star is that it has to have fused at one point in its existence: thus white dwarfs, quark stars and even brown dwarfs are technically considered stars (brown dwarfs fuse duterium for short periods) . Star fusion is a function of mass, so a brown dwarf at population III would still be a brown dwarf.
@@parallaxnick637Yes. And you, with your research skills and dulcet tones, are the right candidate to cover the prehistory and history of the use of the concept of a star. Would you like a cup of flavored metal to go with that?
Nick, I know it's not your focus, but I have to ask: your "You Are Here" coloration bears a strong resemblance to the transgender flag. Is that intentional? I only ask because I'm trans and I love sent trans rep :3 One love

Nick is the only content provider for whom I’d happily sit for an hour awaiting 😅
True

I am enjoying this trip quite a bit. Thank you and your arty friend for doing all the labor involved.
So happy you are continuing this series. This kind of content is what makes RUclips worth watching for me
Thanks to all involved. We all appreciate it
38:43 Fish Paste Draconis, you just gave me the name for the next ship we use in a role-playing game 😀😃😄.
absolutely continue.
it never hurts to know who your neighbors are.
Great work. Thank you Nick and all involved. ✨
The best 43 minutes I've spent in a long time ❤
Glad to see this series continued
This whole series is really good, especially for being your supposed B-side. One of those gems of RUclips.
Please continue this fascinating look into our local neighborhood!
Yaaaay
Please do continue, as I'm loving following the route (where I can) in Elite Dangerous.
Gotta love that astronomical bar talk.
The perfect combination for falling asleep: a soothing voice and interesting facts. I was well-informed before unconsciousness overwhelmed me. (Woke up suddenly at the music at the end tho)
Still my favorite RUclipsr.
mine too!
Thank you for doing what you do!
Loving your work! Keep it up. Liked and Shared!
Man, your videos are simply the best. Good on you. And the graphics are sublime, good on you too. Thanks all concerned :)

Definitely need a part 6 man...Thank you for what you do
Yes, please continue this trip, it is fascinating! :)
Favorite space channel for years now
Please do continue with this series, It is fascinating,
We need an episode or series on every K, and G type star within 50 parsecs
Wooooo part 5 baybeee. This series is going to become some sort of record I swear
Should you keep doing this ?!? Exsqueeze me ? Baking Powder ?
Yes absolutely 110% Your work here is the only Astronomy that excites me these days.
I love it. Eeeek. You’re the best Nick. Always great to hear from you fellow seeker.
Another excellent video nick, keep up the fantastic work. Do you plan on doing a video on black holes one day?
24:11 'alarmingly average'. you gave me the quote of the day 😎.

Would be great to have an interactive version of this map.
In what sense? The map is zoomable. A hypertext version of the map would be cool though.

I accidentally had my playback speed set to 75% and Nick’s voice made me think something was wrong with him lol.

Considering the exceptional content, Nick should be on Nebula. If this channel was, I’d definitely subscribe to the platform.
Incredible quality content that would also benefit from a quality, well-adjusted microphone.
Keep going till the end of the universe ! Well maybe just our galaxy !
Don't ever stop!
Amazing as always.
that was very.. soothing.
I’d missed you had a patreon mate, congrats!
Thank you
I love these!
Excellent
Continue? Yes please!
@ParallaxNick OF COURSE WE WANT PART 6!
Also, nice tip-off to gaming-awareness!
Nick, i love ur content
👏👏👏👏👏👏👏👏
32:24 I love your references to science fiction planets at times. Have we found a Ceti Alpha V equivalent yet 😎?
Alpha Ceti (Menkar) is a red giant, so it's unlikely to have any habitable planets, at least none that it hasn't eaten already.

Brown Dwarfs should be called PROs, Proto-Stellar Remanent Objects.
Nick, could you create a playlist with all your videos for bedtime please?
I have plylists of all my video series, including this one.
" and here is another circle with a catalog number name "
Well, here's hoping we find intelligent life around them so we can learn their names for them
