'''HR 2562b'''是在主星{{link-en|HR 2562|HR 2562}}的[[岩屑盤]]中的{{link-en|次恆星伴星|substellar companion}}<ref name=Konopacky>{{cite journal|last=Konopacky|first=Quinn M.|last2=Rameau|first2=Julien|last3=Duchêne|first3=Gaspard|last4=Filippazzo|first4=Joseph C.|last5=Godfrey|first5=Paige A.

根據{{link-en|NASA系外行星檔案|NASA Exoplanet Archive}}，它的質量是{{jupiter mass|30}}，是{{link-en|質量最大的系外行星|List of most massive exoplanets}}之一。
