GJ 486 b is about 30% larger than the Earth and three times as massive, which means it is a rocky world with stronger gravity than Earth. It orbits a red dwarf star in just under 1.5 Earth days. It is ...

Researchers have discovered more than 6,000 exoplanets in our Milky Way. Of these, the sub-Neptune class, which are smaller than Neptune and more massive than Earth, are the most common. These planets ...

Astronomers have confirmed the existence of exoplanets with extremely small orbits around their stars. But what about exoplanets that get close enough to be devoured by their star, and what if it's an ...
