A team of scientists has discovered two Earth-like planets in the habitable orbit of a Sun-like star.
Using observations gathered by NASA’s Kepler Mission, the team found five planets orbiting a Sun-like star called Kepler-62.
Four of these planets are so-called super-Earth, larger than our own planet, but smaller than even the smallest ice giant planet in our Solar System.
These new super-Earths have radii of 1.3, 1.4, 1.6 and 1.9 times that of Earth. In addition, one of the five was a roughly Mars-sized planet, half the size of Earth.
