- Exoplanet Gliese 12 b: Astronomers have discovered an exoplanet between the sizes of Earth and Venus only 40 light-years away. Gliese 12 b has a radius that is only 4% smaller than Earth’s radius, and is less than 3.9 times the mass of Earth. The exoplanet receives 1.6 times more radiation from its host star than Earth receives from the Sun. If it has no atmosphere, astronomers estimate an average surface temperature at around 42 degrees Celsius (107 degrees Fahrenheit). Earth has an average surface temperature of 15°C (59°F). If it has an atmosphere, Gliese 12 b could maintain surface temperatures suitable for liquid water and possibly life.

A nice holiday destination if there is Oxygen and plenty of water. Only 40 light-years away... It takes only 3750 generations to get there... 😄😄
Not everything is about stealing and colonisation.
Woow. pack 50billion diapers in spacecraft 😅
Sad
This is more likely going to be a less extreme version of Venus at 1.6 times Earth's energy.
Amazing! Thanks guys!
4% down on radius, which is about 12% down on volume - and yet "no more than" 3.9 × the mass: what's it made of, lead? (Yes, I' can see "no more than" could mean "a lot less than", but still.)
Realy I like this video its so interestyng
Conversation with chat gpt 😂
Me: Describe life on gliese 12b
Chat Gpt: Gliese 12b is a hypothetical exoplanet located about 40 light-years away from Earth. It's believed to be a super-Earth, meaning it's larger than Earth but smaller than gas giants like Neptune. However, due to its distance and limited information available, we can only speculate about its characteristics and potential for life.
Me: I thought you didn't have access to information past your last update ...
Chat gpt: You're right. My mistake. Based on the information available up to my last update in January 2022, Gliese 12b is a hypothetical exoplanet, and not much specific information about its characteristics or potential for life is available.
Big achievement UK scientist
Sooo amazing that they share 1 similarity, wow!
Hemos avanzado mucho como cibilizacion,nos hemos organizado inteligentemente❤
Gliese 12 b is a super Earth exoplanet that orbits a M-type star. Its mass is 3.87 Earths, it takes 12.8 days to complete one orbit of its star, and is 0.0668 AU. It is too massive for life. It is too close to the host star for life. The host star is very unstable to support life.
There is 2 things that you got wrong
first: the planet is in the inner edge habitable zone of it's star where it can host life M type star are small,less luminosity so the habitable ring is closer to the star.
Second: the star that gliese 12 b is orbiting produces less solar flares yes M type stars produces a lot of solar flares
Edit: correct me if i am wrong
Question is, who is first to make a computer game about this planet:)
No water inside it ?
Oh .... Some nice,I throughout it was' Deja Vu '
So *that* is were they are coming from 👽😉
Sometimes seeds fall on infertile soil, may they sleep in the warmth of their star
