L 98-59 (TOI-175, TIC 307210830) is a bright M dwarf star, located in the constellation of Volans, at a distance of 10.608 parsecs (34.60 light-years), as measured by the Gaia spacecraft.[4]
Broadband photometry shows that it is an M3 dwarf star with three confirmed terrestrial-sized planets in transit, which were announced in March 2019 by TESS,[5] as well as a fourth non-transiting planet and fifth candidate.[6]
In August 2021, new evidence was announced for a fifth, potentially habitable planet, labeled L 98-59 f. Though still unconfirmed,[6] this planet is believed to have 2.46 times Earth's mass, and an orbital period of 23.15 days.[7][8]
