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.
On average, the Moon is about 238,800 miles (384,500 km) from the Earth. However, because of the elliptical shape of the Moon's orbit, the actual distance varies throughout the year, between 225,804 miles (363,396 km) at the perigee and 251,968 miles (405,504 km) at the apogee.
