NASA’s Transiting Exoplanet Survey Satellite (TESS) has been used to discover Earth-size planet TOI 700 e. It is "orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface," according to NASA's Goddard Space Flight Center.

The TOI 700 system is about 100 light-years away.
