Astrologists have assumed that Exoplanet K2-141b, which is about 202 light-years from Earth, has molten lava as oceans and sheds rocks during rain. Reportedly, the oceans and the atmosphere of this exoplanet are composed of rocks of different kinds. The phenomenon is due to its closeness with the sun and it has a temperature up to 3000°C. K2-141b is 1.5 times the Earth and revolves the Sun in 7 hours.
