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.
At its closest point (known as perigee) the Moon is only 363,104 km (225,622 miles) away. And at its most distant point (called apogee) the Moon gets to a distance of 406,696 km (252,088 miles). This means that distance from the Earth to the Moon can vary by 43,592 km.
