WebEarth and the Moon orbit about their barycentre (common centre of mass), which lies about 4,670 km (2,900 mi) from Earth's centre (about 73% of its radius), forming a satellite system called the Earth–Moon system. On average, the distance to the Moon. With a mean orbital velocity the Moon covers a distance approximately its diameter, or about ...

WebOct 24, 2003 · Saturn – 36,184mi (58,232km) radius; 9x larger than Earth. Uranus – 15,759mi (25,362km) radius; 4x Earth’s size. Neptune – 15,299mi (24,622km) radius; only slightly smaller than Uranus. This illustration … WebEquivalently, you could calculate the total surface area of the sphere with radius equal to the orbital radius of the Moon about the Earth, and then divide the cross-sectional area of the Moon by this total surface area. This must yield the same answer! (c)Pluto has a mean diameter of 2,300 km and a very eccentric orbit around the sun, on top now nck
