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.
Note: The actual Earth-Moon distance ranges from about 360,000 to 405, 000 kilometers, depending on the position in the Moon's orbit. To complete this activity you will need to download the Earth-Moon Distance image. The above image is linked to a larger one, so take the link to the larger image, then download.
