Discovery alert! A nearby super Earth

Cool! A nearby “Super Earth” –   only 21 light-years away in the inner habitable zone of its small, red ‘M dwarf’ star. Almost 3 times more massive than Earth, this exoplanet is 21 light-years away. It takes only two weeks to orbit its star, closer than Mercury is to the Sun. But since M dwarf stars are cool compared to our Sun, the planet still has the potential for water.
