In contrast, Gliese 12 is an unusually inactive red dwarf, meaning its planets face much less harmful conditions. What makes Gliese 12 b particularly intriguing is its size and location.

Artist’s conception of the newly discovered planet Gliese 12 b, which is orbiting a red dwarf star located 40 light-years away. This artist's conception assumes that the planet retains a tenuous ...

Over the next few years, Gliese is going to become a household name. Ceres, the dwarf planet that lives in the asteroid belt between Mars and Jupiter, is being photographed up close for the first ...

The planet has the decidedly unsexy name Gliese 411b — Gliese 411 being the name of the star it orbits, and “b” being the unique label for the world itself — but what it lacks in a cool ...

Gliese-581d is one of five planets to be discovered orbiting red dwarf star Gliese 581. It is bigger than 581g, with a mass at least seven times Earth's and twice as big in size. The planet orbits ...

Indeed, the most promising planet yet found—the "super Earth" Gliese 581 d, seven times Earth's mass—orbits in the habitable zone of a red dwarf star only a third the mass of the sun.

Following the latest estimation, Gliese 581 would be 7 Gyr-old. The purple bars surrounding planets Gliese 581 c and d illustrate the variable distance to the star caused by the eccentricity of ...
