Gliese 832 b
Template:Short description Script error: No such module "infobox".Script error: No such module "Check for unknown parameters". Gliese 832 b (Gl 832 b or GJ 832 b) is a gas giant exoplanet about the mass of Jupiter, located 16.2 light-years from the Sun in the constellation of Grus, orbiting the red dwarf star Gliese 832.[1]
Orbit
The planet takes 10.5 years to revolve around its star at an orbital distance of 3.7 AU;[2] at the time of discovery, this was the longest-period Jupiter-like planet known orbiting a red dwarf.[3] The brightness of the faint parent star at that distance corresponds to the brightness of the Sun from 80 AU (or 100 times brighter than a full Moon as seen from Earth).
Discovery
The planet was discovered at the Anglo-Australian Observatory on September 1, 2008. It would induce an astrometric perturbation on its star of at least 0.95 milliarcseconds and is thus a good candidate for being detected by astrometric observations. Despite its relatively large angular distance, direct imaging is problematic due to the star–planet contrast.[3] Gliese 832 b was confirmed and its orbital solution refined by subsequent studies in 2011,[4] 2014,[5] and 2022.[6] The planet was detected astrometrically by two different 2023 studies, determining its inclination and revealing a true mass close to the mass of Jupiter.[7][2]
