On average the moon is 380,000 km (235,000 miles) from the Earth, a distance of about 110 times its own diameter. A tennis ball would then have to be 110 x 6.7 cm = 7.37 meters (about 24 feet) from the basketball.
The Moon orbits Earth in the prograde direction and completes one revolution relative to the stars in approximately 27.322 days (a sidereal month). Earth and the Moon orbit about their barycentre (common center of mass), which lies about 7006460000000000000â 4600 km from Earth's center (about 34 of the radius of Earth). On average, the Moon is at a distance of about 7008385000000000000â 385000 km from Earth's center, which corresponds to about 60 Earth radii.
