The exoplanet is the first Earth-sized exoplanet in the habitable zone discovered by the Transiting Exoplanet Survey Satellite (TESS). TOI 700 d orbits its star at a distance of 0.163 AU (24,400,000 km; 15,200,000 mi) from its host star with an orbital period of roughly 267.3 days, has a mass 1.72x times that of Earth, and has a radius of around 1.19 times that of Earth. It has been estimated that the planet receives about 86% the energy that the Earth receives from the Sun. It was discovered in January 2020 by the Transiting Exoplanet Survey Satellite (TESS).
