If L 98-59 f exists, it would unlikely be "habitable." Its orbit would likely be between Venus and Earth, and it would have an eccentricity similar to Mercury, possibly placing it in and out of the temperate zone.
It is. So many planets with atmosphere, and even moons, geologically active, and the sun is basically unique in our galaxy (they may be more stars like it, but it's so rare compared to even pulsars).
@@deauthorsadeptus6920 the Sun isn't THAT unique based on what we know. It's a single G type main sequence star - G type stars are around 8% of all main sequence stars, and around half of solar-mass stars (give or take a few percent) are in single systems. It seems to be uncharacteristically calm for a G type star, which is certainly intriguing, but currently there's nothing suggesting that is enormously rare. Pulsars are FAR more rare than sun-like stars.
You have to remember that our current data on extrasolar systems is very heavily biased towards high-mass planets orbiting low-mass stars very very closely on very very short periods. We will need more time and technology to start seeing more planets like the the Earth, with current methods we wouldn't be able to detect our own planet beyond perhaps a few dozen lightyears. At the rate technology is improving though I expect to see some conclusive result within my lifetime, either a detection of life, or the evidence that it is, in fact, exceedingly rare. Right now we don't have enough evidence for either.
One concept I had for a hard sci fi setting, the most valuable material roch people use for decoration isnt gold or silver, but real limestone, which is now very valuable as theres only one place in the universe where it can be found
while this system is very interesting, i think one of the main appealing factors of TRAPPIST-1 is simply how many planets there are, we've only found 1 other system that has more planets than it.
I just learn more information about a new system that i’ve never heard before! Good job btw 😊 Also, here are some ideas for next grand tours Kepler 186 Tau Ceti Kepler 70 Vega Gliese 667 Kepler-64 Kepler 444 Teegarden’s star 61 Virginis HIP 41378 I’d say all of them are underrated cuz people don’t often talk about them or only talk about one or two planets
Seems red dwarfs are easy to study, quick orbits, less brightness, but this makes sun like stars too hard and planet orbits too long, taking much more time, funding, etc. to properly study. Hope they study nearby G types more closely, surprises there for certain.
I think planets like "d" should be called steam planets. And can you do these systems please? Kepler 11 (how b and c don't collide?!), HD 158259, HD 10180, kepler 90 and Tau ceti (though all planets are uncomfirmed).
Tau Ceti has 4 confirmed planets: g, h, e & f. Tau Ceti g is likely a lava planet, there's not much to say about Tau Ceti h other than it's a hot, barren, desert planet, However, what we can say about Tau Ceti e is that it is likely to be a Super Venus with a ridiculously thick atmosphere and high surface temperatures & Tau Ceti f is the coldest of the 4, and, in my opinion, the most habitable one based on what we know about the icy moons and dwarf planets in our solar system having subsurface oceans of liquid water.
2:25 made me think: 'Hi im a red dwarf star and im most famous for murder of life on exoplanets that could potentaly hold life but NOPE i dont feel lole letting em' planets have that' 💀😭🙏
A Grand Tour of the solar sysyem? with all the 288 planetary moons. Also my fav, the dwarf planets. We have great images becouse its our system, so it would look nice for a video.
isn't the whole red dwarf flare striping atmosphere problem not as big of an issue as many make it out to be because most of the super flare are launched from their poles out of the path of most planet?
@6:16 This is not a true statement about there not being a transition between the atmosphere and ocean on a high-temperature ocean planet. At a pressure of 100 bar (venus like), water has a boiling point of about 560K (286 C), which is 186 degrees higher than at 1 bar. The pressure is high but not so much that it would be a fuzzy transition between the liquid/gas states, as there would be in a giant planet (pressure: millions of bar). Therefore, just because the boiling point is increased due to pressure does not mean the pressure is high enough for there to be no distinct liquid/gas transition. The amount of water vapor in the atmosphere is also limited by the saturation vapor pressure, so very high pressure water vapor atmospheres would only be possible at very high temperatures. At our 100 bar 560K example, only 50 bar of pressure could be water vapor, the rest would be liquid. Furthermore, L98-59d is only 416K (neglecting greenhouse effects).
L 98-59f (assuming it exists) might really be one of those very few examples of a planet around a Red Dwarf actually being "habitable".
I'm wondering about the potential goofy ahh orbit though
What about Toi-700
Orbiting a red dwarf star doesn't preclude habitability.
If L 98-59 f exists, it would unlikely be "habitable." Its orbit would likely be between Venus and Earth, and it would have an eccentricity similar to Mercury, possibly placing it in and out of the temperate zone.
I really love the L98-59 planetary system. It deserves more attention!
Definitely
Makes you think about just how absurdly unique our solar system really is.
It is. So many planets with atmosphere, and even moons, geologically active, and the sun is basically unique in our galaxy (they may be more stars like it, but it's so rare compared to even pulsars).
@@deauthorsadeptus6920 We know of many G type stars with no binary partners, so our Sun isn't that unique, just the system surrounding it.

Enjoying the grand tour series, thanks for making these :-)
Yess this is my favourite series, been hoping for a new episode. Nice one Kyplanet, keep em comin ❤
Great, educational show, thank you. Perhaps Tau Ceti system at some point?
One of my favorite systems.
The problem is that there are no confirmed planets orbiting Tau Ceti.
@idkwhattonamemychannel-r4h WDM there is like 4 or 8
Do a grand Tour of Kepler 186 System Kepler 186F has overshadowed the other planets in the system could you please cover the other planets🙂
Never heard of this star system but thanks for sharing all this about it.
while this system is very interesting, i think one of the main appealing factors of TRAPPIST-1 is simply how many planets there are, we've only found 1 other system that has more planets than it.
We have? What's it called? /j
@@A-lik Kepler-90, it's genuinely an interesting system, you should look it up.
@@A-lik kepler-90 is reported to have 8. HD 10180 could have as many as 9, and KOI-351 also has 8. So more than 1 but still few and far in between
@olisomething Wdym Koi-351? That's just different name for kepler 90.
HD 10180 may have 9 planets, but right now we have found 6 of them
I just learn more information about a new system that i’ve never heard before! Good job btw 😊
Also, here are some ideas for next grand tours
Kepler 186
Tau Ceti
Kepler 70
Vega
Gliese 667
Kepler-64
Kepler 444
Teegarden’s star
61 Virginis
HIP 41378
I’d say all of them are underrated cuz people don’t often talk about them or only talk about one or two planets
Kepler-70's planets have strong evidence against them, if not disproven
Do a Grand Tour of Kepler 452 system since Planet Kepler 452 -b is outshine other habitable exoplanets in our galaxy.
kepler-452 only has one planet (kepler-452 b) and it isn’t even confirmed to exist
@@Kyplanet893
Can you do a grand tour of
TOI-178? It’s one of my favourite systems.
Seems red dwarfs are easy to study, quick orbits, less brightness, but this makes sun like stars too hard and planet orbits too long, taking much more time, funding, etc. to properly study. Hope they study nearby G types more closely, surprises there for certain.

Kepler 11 (how b and c don't collide?!), HD 158259, HD 10180, kepler 90 and Tau ceti (though all planets are uncomfirmed).
I read that as "HD 1080p" lmfao
Tau Ceti has 4 confirmed planets: g, h, e & f. Tau Ceti g is likely a lava planet, there's not much to say about Tau Ceti h other than it's a hot, barren, desert planet, However, what we can say about Tau Ceti e is that it is likely to be a Super Venus with a ridiculously thick atmosphere and high surface temperatures & Tau Ceti f is the coldest of the 4, and, in my opinion, the most habitable one based on what we know about the icy moons and dwarf planets in our solar system having subsurface oceans of liquid water.
LET’S GO I’VE BEEN STARVING FOR MORE GRAND TOUR SERIES!!!!!!!
babe wake up kyplanet uploaded
the GOATTTT uploaded again!!
Cool..still waiting for that starship vid though
Can you do extreme stars like Rigel or Betelguese or even brown dwarfs like luhmen 16?
I do love steam worlds, so unique and interesting
Do you have any update on video debunking planet with 752 jupiter masses myth???
Thats the the craziest myth i've ever heard
What in the
That’s a star, a K- type star at that rofl…
He already did in a different video.
@LobedHomunculus we need a deidcated video since its too wide spread
Kepler-186 system tour next?
2:25 made me think:
'Hi im a red dwarf star and im most famous for murder of life on exoplanets that could potentaly hold life but NOPE i dont feel lole letting em' planets have that' 💀😭🙏
All of these planets sound amazing but my favourate has to be d.
Show me a brown dwarf.
yay kyplanet 😊😊😊
can you make a video about L-type main sequence stars
A Grand Tour of the solar sysyem? with all the 288 planetary moons. Also my fav, the dwarf planets. We have great images becouse its our system, so it would look nice for a video.
epic video[its late for me]
Suggestion for next grand tour.
TOI-178.
Cool
isn't the whole red dwarf flare striping atmosphere problem not as big of an issue as many make it out to be because most of the super flare are launched from their poles out of the path of most planet?
d seems like an Enaiposha cousin
I wonder how many of these there are
Do Kepler-33
Can you do YZ Ceti, Teegarden, or HD219134 next plz
Can you do a video of HD 40307?
Grand tour HD 10180
Grand tour of HD 10180 please
This is a very weird question but you literally sound exactly like another channel called theme park crazy, do you also own that channel.
