surface of an orbiting planet. If a planet is too close to its parent star, it will be too hot and water would have evaporated. If a planet is too far from a star it is too cold and water is frozen. Stars come in a wide variety of sizes, masses and temperatures. Stars that are smaller, cooler and lower mass than the Sun (M-dwarfs) have their habitable zone much closer to the star than the Sun (G-dwarf).

If it has an Earth-like atmosphere, it could possess liquid water on its surface.
TESS works by surveying different slivers of the sky one month at a time in succession.

Kepler has given us more exoplanets than any other mission, but TESS has pushed us over the 4, 000 mark. We are now using TESS to identify Earth-sized, potentially habitable candidates suitable for direct imaging and transit spectroscopy by James Webb and beyond.

stars like Proxima Centauri, however, flares are far more common, posing a danger of stripping the atmospheres away from any potentially habitable planets. Around TOI 780, however, which is right at the highest-end of the mass range of red dwarfs, flares may not occur with any more frequency than they do around our own Sun.
Although TOI is an M-class red dwarf, it exhibits no flaring, benefitting potential lifeforms.
