description GJ 832 Overview
GJ 832, also cataloged as Gliese 832, is a red dwarf star of spectral type M2V situated approximately 16 light-years away in the constellation of Grus. It is known to host a multi-planet system, including the gas giant GJ 832 b, discovered in 2008, which behaves similarly to Jupiter in our own solar system. A second planet, the super-Earth GJ 832 c, was discovered in 2014 and is situated near the inner edge of the star's habitable zone. The system remains a significant target for exoplanetary research due to its relative proximity and Earth-sized components.

help GJ 832 FAQ
What is unusual about the orbit of GJ 832 b?
GJ 832 b is a Jupiter-like gas giant on a long orbit around a much smaller red dwarf. Its roughly decade-long revolution makes it a distant counterpart to the close-in planets commonly found around M dwarfs.
Is GJ 832 c still considered a confirmed planet?
The status of GJ 832 c has been disputed because stellar activity can imitate the radial-velocity signal attributed to a planet. It should therefore not be described as securely confirmed without noting that later analyses challenged the original interpretation.
How close is Gliese 832 to the Solar System?
Gliese 832 is about 16 light-years away in the constellation Grus. That proximity makes it one of the nearer red-dwarf planetary systems studied by astronomers.
Could humans see GJ 832 without a telescope?
No. Although GJ 832 is nearby by stellar standards, an M2V red dwarf emits too little visible light to be seen with the naked eye from Earth.
