NASA has discovered a new world, named Gliese 12 b. It is roughly the size of Earth, lies in the habitable zone, and orbits every 12.8 days.

Gliese 12 b orbits around a central star named Gliese 12, which is a type of star known as a red dwarf. Red dwarfs are smaller, cooler and more abundant than the G-Type stars like our Sun.

Gliese 12 b is a rocky planet just 40 light-years away from our own. It orbits around a star called Gliese 12, a cool red dwarf in the constellation Pisces. This star is only 27 percent of the ...

Gliese 12 b, which orbits a cool, red dwarf star located just 40 light-years away, promises to tell astronomers more about how planets close to their stars retain or lose their atmospheres.
