L 98-59 b is an exoplanet having a size between that of the Earth and Mars and a mass only half that of Venus.[2] It orbits L 98-59, a red dwarf 35 light-years away in the constellation Volans. There are at least 3 (possibly 4) other planets in the system: L 98-59 c, d, e, and the unconfirmed L 98-59 f.[2] Its discovery was announced on 27 June 2019 on the NASA website. It was the smallest planet discovered by TESS[4] until the discovery of LHS 1678b,[5] and was the lowest-mass planet whose mass has been measured using radial velocities[2] until Proxima Centauri d was found in 2022.[6]
