- NASA has saidthat its planet hunter satellite TESS had discovered an Earth-sized world within the habitable range of its star, which could allow the presence of liquid water.
- The planet, named "TOI 700 d", is relatively close to Earth- only 100 light years away.
- TESS was designed and launched specifically to find Earth-sized planets orbiting nearby stars.
- A few other similar planets have been discovered before, notably by the former Kepler Space Telescope, but this is the first discovered by TESS, which was launched in 2018.
