A handout picture released by the European Southern Observatory (ESO) on November 13, 2018, shows an artist's impression of the surface of a "super-Earth" planet that has been discovered orbiting the closest star to Earth. - A "super-Earth" has been discovered orbiting the closest single star to our own Sun, scientists said on November 14, 2018, in a breakthrough that could shine a light on Earth's nearest planetary neighbours. Astronomers studied Barnard's Star, a red dwarf just six light years away -- practically in our back garden, galactically speaking -- and noticed the presence of a "frozen, dimly lit world" at least 3.2 times heavier than Earth. The planet, known for now as Barnard's Star b, is the second nearest to Earth outside the Solar System and orbits its host star once every 233 days.
