description Gliese 832 Overview
Gliese 832, also called GJ 832, is a nearby red-dwarf star in the southern constellation Grus, about 4.96 parsecs from the Sun. The NASA Exoplanet Archive lists one confirmed planet, GJ 832 b, detected by radial velocity in 2008, with a roughly 3,853-day orbit. It also lists GJ 832 c as a false-positive planet and notes that its previously reported signal was refuted, so descriptions that present two confirmed planets are outdated.

help Gliese 832 FAQ
What kind of star is Gliese 832?
Gliese 832 is a red dwarf in the southern constellation Grus. It is notable because astronomers have reported two planets in its system.
Which exoplanet around Gliese 832 was discovered in 2008?
Gliese 832 b, a gas-giant planet, was reported in 2008. Its long orbit makes it very different from the smaller, closer planet candidate often called Gliese 832 c.
Why is the Gliese 832 system interesting to astronomers?
The system combines a red-dwarf host star with planets that have very different orbital properties. Reports of Gliese 832 b and Gliese 832 c make it useful for discussing how planetary systems can form around low-mass stars.
Is Gliese 832 a Sun-like star?
No, Gliese 832 is a cooler and smaller red dwarf rather than a Sun-like yellow dwarf. Its planetary environment must therefore be studied with the different brightness and stellar activity of an M-type host in mind.
