Scientists discover new rocky Super-Earth planet

A ‘super-Earth’ exoplanet with a surface temperature slightly cooler than Venus may have an atmosphere able to host alien life, according to a new study. Astronomers from the Max-Planck Institute used different methods of observation to discover the alien world orbiting a nearby red dwarf dwarf star 26 light years away. Gliese 486b is the only planet so far detected orbiting the small star and has a radius 1.3 times larger than the Earth but is 2.8 times more massive. The planet has an iron-silicate composition similar to the makeup of Earth but is much hotter, with a surface temperature of 428 degrees Celsius, the team said. To determine whether the planet still has an atmosphere or is habitable and so suitable for life, astronomers say further studies will be needed in future.
