New Earth-like exoplanet discovered orbiting star 52 light years away

Astronomers found and confirmed the existence of a new Earth-like exoplanet orbiting red dwarf Gliese 3929. The star is 52 light years away and has about a third of solar mass. The exoplanet is about 20 % heavier than Earth and 15 % bigger. However it orbits very close to its star and therefore is too hot for life as we know it.
