A recent study has revealed that a little-known planet about 111 light years away could be a "scaled-up version of Earth" and may be able to host alien life. The exoplanet known as K2-18b has been described as a potential 'Super-Earth'. Researchers at the University of Toronto in Canada made the discovery by scouring data collected by the European Southern Observatory. They also discovered a new planet in the same solar system. Both planets orbit K2-18, a red-dwarf star located about 111 light-years away in the constellation Leo.
