Hereâs how long the iOS 8.1 upgrade takes. You should make sure you start the iOS 8.1 download on a good internet connection, when you have time to wait for the download to complete. You need WiFi to start this and you need at least 50% battery life.
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 is at an average distance of 238,855 miles (384,400 kilometers) away from Earth. That is about the width of 30 Earths. Because the Moon does not orbit Earth in a perfect circle, but instead travels in a slightly elliptical orbit, its distance from Earth varies between 225,700 miles (363,300 kilometers) and 252,000 miles (405,500 kilometers).
