older. The inner world, Kepler-36b, is a rocky planet 1.5 times the size of Earth and weighing 4.5 times as much. It orbits about every 14 days at an average distance of less than 11million miles. The outer world, Kepler-36c, is a gaseous planet 3.7 times the size of Earth and weighing 8 times as much. This 'hot Neptune' orbits once each 16 days at a distance of 12 million miles. The two planets experience a conjunction every 97 days on average. At that time, they are separated by less than 5 Earth-Moon distances. Source: The Coming Crisis
