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.
After careful measurements, it has been found that at its farthest point in its orbit (apogee), the moon is about 405,000 kilometers away from Earth. In comparison, at the nearest point in its orbit (perigee), the moon is about 360,000 kilometers from the earth.
