HD 108863

HD 108863 is a subgiant star, the primary of a binary star system $1.6$ away, belonging to spectral class K0. Its age is younger than the Sun's at $1.8$ billion years. The primary star is slightly enriched in heavy elements, having 115% of solar abundance. The primary star does not have detectable flare activity.

In 2014, a poorly characterized co-moving stellar companion HD 108863 B, likely a main sequence star of spectral class between F6 and G4, was discovered at a projected separation of 16.065 AU.

Planetary system
In 2011 one superjovian planet, HD 108863 b, on a nearly circular orbit around star HD 108863 was discovered utilizing the radial velocity method. The planet does not transit its host star.
