by The L 98-59 planetary system contains two non-transiting planets and three transiting terrestrial planets, one of which is a warm rocky world with half the mass of Venus.
L 98-59 is a bright M3V-type dwarf located 34.6 light-years away in the southern constellation of Volans.
Also known as TOI-175 or TIC 307210830, the star is about one-third the mass of the Sun.
According to the new research, L 98-59 hosts five planets: L 98-59b, c, d, e and f.
“The fact that L 98-59 is an M-dwarf sets this system apart among multiplanetary systems,” said lead author Dr. Olivier Demangeon from the Instituto de Astrofísica e Ciências do Espaço at the University of Porto and his colleagues.
“According to the exoplanet archive and the recent literature, only seven multiplanetary systems are currently confirmed — including L-98-59 — around M-dwarfs for which the planetary masses and radius of at least two planets have been measured.
