Researchers report the discovery of a super-Earth orbiting the star GJ740, a red dwarf star situated some 36 light years from Earth. In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses...
