Caption: Kepler-78b is a planet that shouldn't exist. This scorching lava world, shown here in an artist's conception, circles its star every eight and a half hours at a distance of less than one million miles. According to current theories of planet formation, it couldn't have formed so close to its star, nor could it have moved there.
