An illustration of the newly discovered Earth-sized exoplanet Gliese 12 b and its red dwarf parent star.Using NASA's Transiting Exoplanet Survey Satellite , scientists have discovered a tantalizing world that is remarkably close to our solar system.. The planet is estimated to have a width around 1.1 times that of Earth, making it similar to our planet as well as Venus, often called our world's solar system"twin.
Gliese 12 b receives around 85% of the radiation that Venus gets from the sun, but is thought to have a much cooler surface temperature of 107 degrees Fahrenheit compared to Venus' surface temperature of 867 degrees Fahrenheit ., one can support life and has a favorable atmosphere, while the other is an inhospitable hellscape with temperatures hot enough to melt lead. Studying Gliese 12 b could help us understand why this is the case.
"It's interesting to know about planets around the small stars, what they might be like, and whether such planets could have life," Van Eylen added. "I think next really is to nail down the mass of the planet. We are already actively doing that as part of the team, which is a radial velocity telescope," Palethorpe said."Then we've also got another proposal accepted with the European Organization for Astronomical Research in the Southern Hemisphere , which is another radial velocity telescope. And so, hopefully, from kind of the radial velocity observations, we will do this.
The two teams' research was published on Thursday in The Monthly Notices of the Royal Astronomical Society and The Astrophysical Journal Letters. to keep talking space on the latest missions, night sky and more! And if you have a news tip, correction or comment, let us know at:
