Gliese 581g was, therefore, the most Earth-like exoplanet known at the time, in terms of its mass (at least 3.1 times Earth's mass) and the amount of heat it received from its star, as it orbited ...

The distance separating Gliese 12 and Gliese 12 b is just 7% of the distance between Earth and the sun, NASA said. The planet receives 1.6 times more energy from its star than Earth does from the sun.

The JWST is currently conducting a similar investigation for the seven Earth-like planets of the TRAPPIST-1 system, located around 40 light-years away. These planets resemble Gliese 12 b in that ...

But Gliese 12 b, located 40 light-years away in the constellation Pisces, could be the most sensational find to date. Its discovery is outlined in a paper published today in Monthly Notices of the ...

"Using the Mid-Infrared Instrument on JWST, we monitored GJ 367 b for 12.7 h, corresponding to 1.6 planetary orbits," the researchers wrote in the paper. The observations found that Gliese 367 b ...
