Terdapat dua eksoplanet raksasa yang mengrbit bintang ini. ''[[Very Large Telescope]]'' milik Observatorium Selatan Eropa ([[Observatorium Selatan Eropa|ESO]]) mencitrakan kedua planet tersebut menggunakan istrumen [[Spectro-Polarimetric High-Contrast Exoplanet Research|SPHERE]]-nya, yang menghasilkan gambar nyata pertama yang yang memuat citra beberapa planet mengelilingi bintang yang tampak seperti Matahari.<ref name="ESO_Bohn">{{cite web |last1=ESO/Bohn |title=First ever image of a multi-planet system around a Sun-like star (uncropped, with annotations) |url=https://www.eso.org/public/images/eso2011b/ |website=ESO |publisher=European Southern Observatory |accessdate=24 July 2020 |archiveurl=https://web.archive.org/web/20200724161316/https://www.eso.org/public/images/eso2011b/ |archivedate=24 July 2020 |date=22 July 2020}}</ref><ref name="Wall">{{cite news |last=Wall |first=Mike |title=Multiplanet system around sunlike star photographed for 1st time ever - The two newly imaged planets are huge — 14 and 6 times more massive than Jupiter. |url=https://www.space.com/multiplanet-system-sun-like-star-first-photo.html |date=22 July 2020 |work=Space.com |accessdate=22 July 2020 }}</ref>
