Earthlike moons of a gas giant. Artwork of three Earthlike moons (one at upper right,two more at lower left) orbiting an alien gas giant planet. The shadow of one of the moons is seen passing over the clouds of the planet below. The orbit of the gas giant planet,and the size of the moons,have to fit within a narrow range for them to have a surface temperature suitable for liquid water,and for them to retain an atmosphere. As of 2010,hundreds of planets have been detected around other stars | |
