Nov 20, 2024 · In 2010, astronomers discovered what they thought was the most Earth-like planetary candidate known at the time orbiting a red dwarf star. Today, astronomers no longer think the planet, which...

Gliese 581 (/ ˈɡliːzə /) is a red dwarf star of spectral type M3V which hosts a planetary system, 20.5 light-years (6.3 parsecs) away from Earth in the constellation Libra.

Apr 25, 2007 · Two years ago, the same team of astronomers already found a planet around Gliese 581 (see ESO Press Release eso0539). With a mass of 15 Earth-masses, i.e. similar to that of Neptune, it orbits its host star in 5.4 days.

Oct 1, 2010 · The planet, Gliese581g, is one of two new worlds discovered orbiting the red dwarf starGliese 581, which now has a family of planets that totals six. [Tourthe six Gliese 581 planets.]
