Exoplanets circle stars beyond our Sun, but only a handful smaller than Earth have been discovered, according to NASA. UCF 1.01 is about 5,200 miles in diameter, slightly larger than Mars, smaller than Venus.

It’s so close to its star – GJ 436 is about half the size of our Sun – that it revolves around it once every 1.4 days (about 33 1/2 hours.) It’s so hot, at least 1,000 degrees Fahrenheit, that it has no atmosphere and may have a molten surface.
