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's orbit around Earth is not a perfect circle, but elliptical, with one side closer to Earth than the other. As a result of the Moon's elliptical orbit, the distance between the Moon and Earth varies throughout the month and the year. On average the distance is about 382,900 kilometers (238,000 miles). The point on the Moon's orbit closest to Earth is called the perigee and the point farthest away is the apogee.
