Scientists are certain that life, as we know it, could not exist on the outer planets in our solar system. There are three fundamental flaws in the 'other planets are warming' argument. Uranus' moons are named for characters in William Shakespeare's plays so you’ll find Ophelia and Puck in orbit. Moons — also called natural satellites — come in many shapes, sizes and types. As these planets grew in the early solar system, they were able to capture smaller objects with their large gravitational fields. See no ads on this site, see our videos early, special bonus material, and much more.
