HD 86081 is a yellow-hued star in the equatorial constellation of Sextans. It has the proper name Bibhā, the Bengali form of a Sanskrit word meaning a bright beam of light.[7] The star is named after the physicist Bibha Chowdhuri (1913-1991), who studied cosmic rays.[citation needed] This name was suggested in the 2019 NameExoWorlds campaign.[7] With an apparent visual magnitude of 8.73,[2] this star is too dim to be viewed with the naked eye but can be seen with a small telescope. It is located at a distance of approximately 340 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +31 km/s.[2]
