Earth moon radius
WebIn celestial mechanics, the Roche limit, also called Roche radius, is the distance from a celestial body within which a second celestial body, held together only by its own force of gravity, will disintegrate because the first body's tidal forces exceed the second body's self-gravitation. Inside the Roche limit, orbiting material disperses and forms rings, whereas … WebThus, the Sun occupies 0.00001% (10 −5 %) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly one millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 astronomical units ... Harrison H. Schmitt, an astronaut in the Apollo 17 mission, with the Moon and Earth in the background.
