New 'super-earth' discovered 33 light-years away
Spain-based researchers have discovered a new 'super-earth' planet in orbit around a star around 33 light-years away. The planet, GJ 536 b, has an estimated mass around 5.4 times that of Earth, and orbits its parent 'red dwarf' star once every 8.7 days. A 'super-earth' planet is defined as one with mass between 1 and 15 Earth masses.
