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 average distance from Earth to the Moon is 384,403 kilometers or 238,857 miles, but the actual distance varies over the course of the orbit of the moon. Depending on the Moon's location in its orbit, it is between 225,623 and 252,088 miles away from Earth. This is about 30 times the diameter of the Earth.
