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's current orbital distance is 384,400 km (238,900 mi), or 1.28 light-seconds. This is about thirty times the diameter of Earth, with its apparent size in the sky almost the same as that of the Sun, resulting in the Moon covering the Sun nearly precisely in total solar eclipse.
