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.
When the Moon is away from Earth, it is called apogee. At apogee, the distance of the Moon from Earth is 406,300 km (252,463 mi). The average of these two distances gives the actual Lunar Distance, 384,400 km (238,855 mi). The time taken by light to travel this distance is 1.26 seconds. Lunar distance has some significance in astronomy.
