HD 96167 is a double star system with an exoplanetary companion in the southern constellation of Crater. The apparent visual magnitude of this system is 8.09,[2] which is too faint to be readily visible to the naked eye. It is located at a distance of approximately 279 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +12 km/s.[1]
The primary component, designated HD 96167 A, is an ordinary G-type main-sequence star with a stellar classification of G5V.[3] It has also been classified as a subgiant star,[7] suggesting it is somewhat more evolved having exhausted the hydrogen at its core. The star has an absolute magnitude of 3.41,[2] placing it about a magnitude above the main sequence.[7] It is metal rich and is around six billion years old.[5] This star is larger, brighter and more massive than the Sun.
A faint co-moving stellar companion, component HD 96167 B, was detected in 2014 at a projected separation 506 AU from the primary. The existence of additional stellar companions was ruled out at projected distances from 51 to 740 astronomical units.[4]
In 2009 it was found that primary star HD 96167 A is orbited by a Jovian planet on an eccentric orbit.[7]
