For nearly four years, NASA’s Kepler spacecraft whisked through space, surveying our corner of the galaxy. It monitored more than 150,000 stars, looking for planets about the size of Earth that belonged to other solar systems. The mission didn’t disappoint; Kepler found countless examples of a type of planet known as a super-Earth

These faraway planets might remind you of home — they’re rocky, smaller than gas giants, located near their star and sport a relatively thin atmosphere. But they’re way larger than the blue marble: These super-Earths are a honking two to 10 times bigger in mass than our Earth.
