Scientists discover a nearby ‘super-Earth’

Researchers have discovered a “super-Earth” type planet, GJ 536 b, whose mass is around 5.4 Earth masses, in orbit around a nearby very bright star. The exoplanet is not within the star’s habitable zone, but its short orbital period of 8.7 days and the luminosity of its star, a red dwarf which is quite cool and near to our Sun, make it an attractive candidate for investigating its atmospheric composition.
