Gliese 581d / ˈɡliːzə / (often shortened to Gl 581d or GJ 581d) is a doubtful, and frequently disputed, exoplanet candidate orbiting within the Gliese 581 system, approximately 20.4 light-years away in the Libra constellation.

May 18, 2011 · Gliese 581d, an exoplanet (planet outside our solar system) seven times the size of Earth, orbits a star called Gliese 581 that is 20 light-years away in the constellation Libra.

May 22, 2011 · Two candidates have already been discarded, but a third planet, Gliese 581d, can be considered the first confirmed exoplanet that could support Earth-like life.

May 17, 2011 · Gliese 581d orbits outside of 581g, far enough away from its star that researchers first thought it too cold for life when it was originally discovered in 2007. But a strong greenhouse...

Oct 25, 2024 · The planet furthest out, Gliese 581d, orbits its host star in 66.8 days, while Gliese 581 e completes its orbit in 3.15 days.

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.

Jul 4, 2014 · Two potentially habitable planets in the Gliese 581 system are just false signals arising out of starstuff, a new study said. Gliese 581d and 581g are (study authors said) instead indications...

Gliese 581d is the third planet discovered around the red dwarf star Gliese 581, which has a mass 0.31 times that of the Sun and is 20.4 light-years from Earth. Gliese 581d orbits its star every 66.64 days at a distance of 32.9 million km (20.5 million miles), which is within the habitable zone.

Mar 9, 2015 · Gliese 581 (GJ 581) is a red dwarf star located in the constellation Libra, only 20 light-years away. Beginning in 2005, scientists discovered a series of exoplanets around it, eventually finding evidence for four low-mass, probably terrestrial exoplanets.

A new analysis shows that there is no signal of the planet Gliese 581 d after stellar activity reduction. Gliese 581 is a red dwarf in the constellation Libra. It is the 89th closest star to the Solar System.
