Astronomers Have Found a Super-Earth Near The Habitable Zone of Its Star
The very tiny motion of a small star has revealed the presence of a super-Earth exoplanet, orbiting at a distance that is close to habitable.Around a faint red dwarf called Ross 508, located just 36.5 light-years away (yet too dim to be seen with the naked eye), astronomers have confirmed the existence of a world just 4 times the mass of Earth. Given what we know about planetary mass limits, that means the world is likely to be terrestrial, or rocky, rather than gaseous.
The exoplanet, named Ross 508 b, is unlikely to…
