A hot, metallic, Earth-sized planet with a density similar to Mercury - situated 339 light years away - has been detected and characterised by a global team of astronomers, including the University of Warwick.
Named K2-229b, the planet is almost 20% larger than Earth but has a mass which is over two-and-a-half times greater –and reaches a dayside temperature of over 2000°C (2330 Kelvin).
