Explanation: The Kepler Space Telescope has identified three super-earths orbiting a ‘cool dwarf star’ about 267 light years from the Earth. Super-earths have a mass higher than the Earth, but are lighter than gas-filled planets like Neptune and Uranus. They are good candidates for having terrestrial surfaces and oceans that may support life. There are about 55 confirmed super-earths till date.
