HD 116029 is a binary star system about Шаблон:Val away.

The primary subgiant star HD 116029 A belongs to the spectral class K1. Its age is younger than the Sun`s at 2.7Шаблон:± billion years.[1] The primary star is slightly enriched by heavy elements, having 130% of solar abundance.[2] The primary star does not have detectable flare activity.[3]

In 2016 the co-moving binary stellar companion HD 116029 B was detected. It is a red dwarf star of visual magnitude 16.[4] The companion was confirmed orbiting the primary at a projected separation of 171 AU in 2017.[5]

Planetary system

In 2011 one superjovian planet, HD 116029 b, on a mildly eccentric orbit around star HD 116029 A was discovered utilizing the radial velocity method.[2] One more planet on a wider orbit was detected in 2016. The planets b and c are orbiting in a 2:3 orbital resonance.[6]
