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.
Our moons average distance from the Earth is 384,399 km (238,854 miles). [The average center to center distance is 384,403 kilometers] However the Moon's orbit is elliptical and the distance therefore varies during its orbit though, from around 405,696 km (252,088 miles) at its furthest (Apogee) to 363,104 km (225,622 miles) at its closest (Perigee).
