- Luyten b is a rocky exoplanet orbiting within the habitable zone of the nearby red dwarf Luyten's Star, in the constellation Canis Minor (just to the right of the bright star Procyon). With a visual magnitude of 9.9, it's too faint to be viewed with the unaided eye.
with an Earth Similarity Index of 0.94: Gliese 581 g!
Gliese 581g, discovered in 2010, is an extrasolar planet that orbit the star Gliese 581, approximately 20.4 light years from Earth in the constellation Libra. It is notable as it is thought to be in the middle of the habitable zone of its star.
with an Earth Similarity Index of 0.95: TRAPPIST-1e !
TRAPPIST-1e is an almost Earth-sized terrestrial extrasolar planet orbiting around the ultra-cold dwarf star TRAPPIST-1, located approximately 39 light-years away from Earth in the constellation Aquarius.
T present, it raises the chances for the planet to have a more Earth-like atmosphere instead.
with an Earth Similarity Index of 0.95: Teegarden b !
Teegarden b is an exoplanet found orbiting within the habitable zone of Teegarden's Star, an M-type red dwarf in the constellation Aries, about 12 light-years from the Solar System.
with an Earth Similarity Index of 0.98: KOI-4878.01 !
Discovered in 2015, KOI-4878.01 is an extrasolar planet that orbits the F-type main-sequence star KOI-4878.
It is located about 1075 light years from Earth in the constellation Draco.
. Kepler-438B
In terms of hope, it's unlikely at present that Kepler-438B would be a planet we would reach in the near future. Because this planet (discovered in 2015) is actually 470 light years from Earth. That being said, it might just be the planet we need right now, as it's been deemed one of the most Earth-like planets in the entire universe.
. Kepler-452B
What's with all the Keplers? Ok, that's not really a question I was just curious after having two of these back to back.
. Kepler-186f
Another Kepler planet, this one was actually the first planet to be defined as Earth-like because it lived in the "habitable zone" of a star.
. Barnard’s Star b
Found in 2018, and located a mere 6 light years away from Earth (that's really close for the record), Barnard’s Star b is the 2nd-closest exoplanet to Earth right now.
. Proxima-B
Remember when I said that barnard's Star B was the 2nd-closest exoplanet to Earth? Well, here's No.1 Proxima-B is only 4.2 light years away from Earth, and it was found in 2016.
. Kepler-62F
Oh yeah, another Kepler planet, but also another "Super Earth", and was discovered in April of 2013. One of the biggest differences between Kepler-62F and other planets on this list is its star. Because the star that the planet orbits is actually 7 billion years old. In terms of star life, that's pretty long.
Still, scientists believe it could support life. But given the planets nature, it would likely be localized to certain areas of the world.
. Kepler-22b
Found 600 light years from Earth, Kepler-22b is within the Habitable Zone of its star. As well as being twice the size of Earth, the yearly rotation is somewhat similar to our own at about 292 days.

Just for reference, we can't even travel 10 light seconds.
Great video. Searching for these Earth like planets sort of reminds me of searching for Paradise planets in No Man's Sky. They're out there, there's many of them, but the actual ones worthy of a base take a while to find.
Very interesting and informative video Thank You so much for posting this I really learned a lot BTW I cant believe Ive never come across your channel , Thanks again
The James Webb Space Telescope and future space imaging telescopes will help. Spectacular video and keep the videos coming till we reach a Type 1 Civilization in about 100 years.
The planets with such low orbital periods are terrible investments: most of them will be tidally locked and you will only have an inhabitable band that is in permanent twilight.
luyten b
88% chance of being rocky
surface gravity:15.52m/s2 / around 66% higher than earth
temp:19 celcius if it has a similar atmosphere to earth
star:very quiet
1 year = 88 days
its is luckily not tidally locked because of its large orbital eccentricity which also gives it seasons
(my favourite exoplanet)
There is no habitable zone orbiting a red dwarf. Unless we are talking about marvel superheroes.
there absolutly is around the quiet ones
Great video !
Increasingly it's being found that the habitable zone around M-type stars is not actually habitable due to the extreme close proximity to the star, tidal locking and extreme solar flares.
Mars average surface temperature is -65c not +63c!!
There may as well be ZERO, because there is ZERO chance to travel the vast distance to reach them.
It would take hundreds of thousands of years to make such a journey. Earth is all there is.
at the moment
Zefram Cochrane will be born in 2030. I hope the proper arrangements are already being made. Need that warp capability. Don't worry about the messy parts before that.
There is a planet exactly like earth near Neptune which I read about in the 70's from an encyclopedia.
I'm trying to understand why science never discussed this planet.
There is so much more to being "earth-like" than merely being of a certain size and mass and being within a star's hypothetical habitable zone. While l agree those are promising signs to look for in exoplanets, they are only a few pieces of a massive puzzle.
Also, given how temperamental red dwarf stars can be, and how closely planets have to orbit them to get enough energy for our sort of life to develop, l have a feeling we are going to find that red dwarfs are not promising for complex life development. And yet, so much focus is currently being put on planets orbiting them.
Yup, red dwarfs give very little heat and light, so for their planets to have liquid water they need to be very close to the star, so they usually end up tidally locked. Which isn't useful if you want to occupy the whole planet.
I also have been having a lot of misgivings about so called Earth like planets orbiting red dwarf stars
@@DoctorNemmo they do usually end up tidally locked but when they dont and the star is a very queit one like luyten b it ends up extremely good for chances of life
Why did the sound and "feel" of the video change so dramatically in the middle of the video?
There Could be Billions of Earth 🌎 sized and Super Earth 🌎 planets out there in the Universe
I guess over a billion
Hell yea another earth like planet!! Oh yea wait, here comes the earth-like exoplanet’s go-to:…it’s a freaking red dwarf…tidally locked..blah blah
There is no "habitable zone" orbiting a fecking red dwarf with 200 times more plasma storms than our sun per year. I guess Hulk could live there though.
not all red dwarf planets are tidally locked
for example luyten b and its because of the orbital eccentricity
Earth has an Earth Similarity Index of 1.01 with a 1% margin of error :P

I think people get far too carried away with the potential features of exoplanets and make some grand statements built on some tremendous assumptions. Of course we can get some points of data with observations, but the study is extremely new and we have a lot of holes in our understanding of planets and stars (not to mention all of the things that we don't know that we're unaware of.)
We only have excellent information on our planet and our star. We do have some very good information on a couple other planets in our star system and other nearby objects like asteroids, meteors, comets, and moons. But the way we gather information about exoplanets is extremely limited with only contextual understandings and inferences based on the data from our own star system. We infer atmospheric conditions/constitutions through spectral analysis and can assertion masses and distances, but that doesn't tell us about many other variables that change these conditions for different planets around different types of stars.
I'm not saying that we are just spitballing with all the data on exoplanets, but we do make a lot of assumptions and inferences based on our very limited knowledge. If we observed our own solar system from several light years away, we would likely make many different assumptions that are incorrect. Venus, Earth, and Mars are all within the "habitable zone" of our star, yet the conditions are widely varied. Plus, these kinds of distances are insurmountable with current technology or technology that could be developed in the foreseeable future to make the distance traversable within a single generational ship for humans.
We may have found some planets similar to Earth, and that's great. Being realistic however, even if we find another planet that appears to be an Earth twin. Does that mean it would be a place to set a colony. Well maybe, if we think about it however, our own planet the one we evolved on, is forever trying to kill us. So a different planet one we didn't evolve on would likely try even harder. Earth like planets would be great places to have habitats orbit especially if they have life then we could study that life assuming it's basic life or not technology using life. We could build habitats and have controlled visits to the planet. I'm betting that as we establish the colony on Mars we will find out that Earth is a much friendly place. Even the Moon may work better than Mars since it is only rock and has never had life living on it. Not saying that Mars has had life, but if it did or does, I'm guessing it will want to kill us. I'm excited to see humans land on Mars and I hope I'm wrong and that we only have everything else to deal with and there is no human killing life on Mars but they should send folks in small groups and see. Lab rats I guess.
Mars is already a pipedream. Sending humans to another star system is delusional. Sending anything to another star is delusional. They are way, way, way too far away.
Dream on buddy, maybe you are watching too much Star Trek or something. First of all, with our current Space Craft technology, their max speed is about 37,000 MPH. But it took like 10 years just to get to Neptune & Pluto. Proxima Centari is the next closest star which is 4 light years away. Now do the math our current spacecraft can reach it in about 75000 years. And some of these planets are a lot further than that. I bet you are asking about traveling at light speed. Well I don't believe that is possible, not just because we don't have the capability, but think about this: Space is vast we don't know what's out there. Suppose we build a spaceship that travels 650,000 MPH.
and it hits a micrometeror somewhere in space. What kind of impact would that
have on our puny little spacecraft. Yeah I know, you are probably young & optimistic, but you should look at reality. We humans are too busy with wars & killing each other
to ever come together & devise such a
grandiose plan and fall through with it. There is too many factors to consider.
These planets might have water & be earth like to a degree, but that doesn't mean they
could support us. We don't have that much information about them yet. You are dreaming a bit big kid. Why don't you put your mind to something more realistic. Like scientists are working on a plasma rocket that could propel a craft upstairs to
650,000 MPH, well that's a start, progress not perfection
You're right, but a buzz kill
@@robertnagel3972the fastest probe was the Parker solar probe at 500,000 km/h. Its a start but still ridiculously slow. The only hope we have is a more advanced life form teaching us how to travel potentially bending space/ wormholes, matching frequency of certain planets and sort of phasing in and out. Its ridiculous that humans still haven't travelled further than the moon 50+ years after we first went with all the advancements in technology...
@@andybeeres2452 It's because we are too busy fighting worthless wars to ever come together and put our minds together to achieve such a project. Sad but true
Your voice-to-text needs a little more editing. It's "Cygnus" at 10:05.
Ok .. How do they determined the age of a star?
By the mass, composition, temperature and brightness we know more or less the phase of star evolution.
It is a great discovery for science to find Earthlike planets. But we should protect and save our own Planet Earth from destruction. Since it is already the perfect planet that God gave to us.
I think koi 4878.01 is the most promising to be just like earth.
Well koi 4878.01 is orbiting an f type star and it will only last 4-6 billion years as it burns it's hydrogen much faster than the sun, and it's low metallicity and high space velocity suggests it's older than the sun, it wouldn't be enough time for life to develop, unless some freak event occurs and life evolves faster than on earth. And that's if 4878.01 even exists,as it's existence is not yet proven. If it does exist, koi 4878 is likely to be a helium fusing red giant by the time we travel the 1075 light-years to get there
Biggest drawback in finding another life is we consider water is precondition for life but it's not true, may be other life needs different chemicals for living, or they may he living only on air, or eating stones, why are we denying this probability
we are not .its just that as far as we know all carbon life needs H2o is some way or another and that makes it a great indicator for possible life and narrows down our search
Asimov in his novel foundation and earth mentioned proxima b exactly like this video, but it was in 1980s, asimov is true genius, or may be he the prophet of alien god, and telling us our future
I doubt there's a number high enough! 🙉
Hii 🙈
@@mars-jr5uu 🙊 !
@@mm-dw4rr how are you
@@mars-jr5uu To be honest times are tough. Really tough. Are you traveling okay?
sorry but the x2 doesnt pass until monday tuesday
You can see it but can't touch it.Hahaha.😢
Quran says, there are six earths similar to this one, I couldn’t figure out How many you figured out here. Pls ans if possible
no water on any of them
Dudes determining that a planet is earthlike from a gabillion kilometers away. Always amusing..
Like your level of comprehension on the subject that involves the properties of light as it reflects or travels through the different elements of the periodic table.
Yes, very amusing indeed...
A conservative estimate would be somewhere in the TRILLIONS. People fail to grasp the vastness of the Universe.
There Are 7 Earths in All.
One Day This So Called Science Will Know This Fact.
7 Earths And Seven Skies & 7 Suns.
Every Earth has it's own species.

Umm thats a lie it seems! Space Engine Shows me what Leotin B looks like oh wait its not there. It shows Proxima B is cold lifeless planet in Space Engine. Space Engine is a game created by an Space X or NASA staff member in 2015 (I Think).

6 as much as I like the content of this channel, I can't bring myself to subscribe if the script writing is so sloppy, or the chatbot used to read the script is so piss poor. The first example given says Earth has an equilibrium temperature of 18 degrees Celsius, then the second example says Earth has the equilibrium temperature of 15 degrees Celsius. Somebody do some editing before this video is released!
Oh my god!!! Gravity wells suck!!!
Omg
How many planet earth like in are universe? My answer is more than billions like earth some are most beautiful planet than earth,many living human being, all figure look like people,,,not creature,. create by god, " perfect",,animal is animal , human being is people, some planet no human being, some planet only animal,
Hopefully they are all too far away for Humans to inhabit to turn into a human waste dump.
They are all too far away.
No need to hope. It's already known. Yes, it is too far. The thing we don't know, however, is whether or not humans exist on other planets already. We assume life on other planets would be extremely different from our own. But we don't know that for sure. We could be a common parasite that exists on billions of other planets.
Omg every system has an Earth and a Neptune.
That’s how the multiverse works.
Makes more sense when you understand that Neptune is indigo like Vishnu & Shiva.
The correct name to satisfy the astrology/astronomy/mythology/cosmogony is Khaos.
You got Atlas wrong too. That is Atlas not Uranus.
Oi.
none, the correct answer is none
thats awfully pesemistic
This is amazing Gods creation.
Absolutely God creation is amazing and so beatiful he is amassing God.Halleluja to Jesus☺😊☺
No one.
