| − | Regulus C is a red dwarf star with a spectral type M5 V. The star is around 20 percent of the Sun's mass but is only 0.31 percent its visual luminosity. An [[terrestrial planet|Earth-like]] world around the star would be centered around 0.056 AU in order to have liquid water on its surface. At such a close orbit, the planet's year would only be 10.7 days, nd the planet would be [[Tidal lock|tidally locked]]. | + | Regulus C is a red dwarf star with a spectral type M5 V.
