TOI-270, aka L 231-32, is a red dwarf located about 73.2848 lightyears from the solar system, it's orbited by three planets: a low-density super-Earth and two mini-Neptunes. TOI-270's planets have a small series of resonant orbits (b:c = 5:3 | c:d = 2:1). Additionally, TOI-270 d likely has a hydrogen rich atmosphere with it's strongest single light absorber likely being water, as revealed via a transit observation with Hubble.
