Gliese 832

Gliese 832 (iné označenia: Gl 832, GJ 832, CD-49°13515, HD 204961, HIP 106440, LHS 3865, PLX 5190) je červený trpaslík spektrálneho typu M2V[1] v súhvezdí Žeriav vzdialený 16,16 ± 0,08 ly (4,95 ± 0,02 pc) od Slnka. Má zdanlivú hviezdnu veľkosť 8,66.[2]

V roku 2014 medzinárodný tím astronómov pod vedením Roberta A. Wittenmyera z Univerzity Nového Južného Walesu (University of New South Wales) v Sydney v Austrálii ohlásil objav exoplanéty GJ 832 c obiehajúcej vnútorným okrajom obývateľnej zóny hviezdy GJ 832.[3] Jej index podobnosti so Zemou činí 0,81.[4]
