Use the measuring tape to find a spot 23 feet 9 inches away from the middle of the basketball.

Earth is the third planet from the Sun and the only astronomical object known to harbor life.According to radiometric dating estimation and other evidence, Earth formed over 4.5 billion years ago. This view from the Apollo 11 spacecraft shows the Earth rising above the moon's horizon.

Make use of Google Earth's detailed globe by tilting the map to save a perfect 3D view or diving into Street View for a 360 experience. Given the Earth's greater size, it naturally appears larger in the lunar sky. The Earth and the Moon's barycentre, their common center of mass, is located 1,700 km (1,100 mi) (about a quarter of Earth's radius) beneath Earth's surface. The Earth revolves around the Earth-Moon barycentre once a sidereal month, with 1/81 the speed of the Moon, or about 12.5 metres (41 ft) per second. Our moon is the fifth largest of the 190+ moons orbiting planets in our solar system. Coordinates of the center of the terrain are 85 degrees east longitude and 3 degrees north latitude. Google Earth is the most photorealistic, digital version of our planet.

Being that the distance from the Earth to the Moon is exactly the same as the distance from the Moon to the Earth (what a coincidence, I know) it's fairly easy to figure out how big the earth would look from the Moon. This represents Earth. Thousands of new, high-quality pictures added every day. And how often are they updated? Under the surface.
