The first Earth-sized habitable-zone planet found by TESS.

TOI-700 d is a dense, rocky, near-Earth-sized exoplanet in the habitable zone of the red dwarf TOI-700, about 101 light-years away in Dorado. It is the outermost of four confirmed planets around the star and was announced on 3 January 2020 as the first Earth-sized habitable-zone planet found by the Transiting Exoplanet Survey Satellite (TESS).

It orbits at 0.161 AU every 37.4 days, has a radius about 1.19 times Earth's and receives about 88% of the energy Earth gets from the Sun.
