| - | If the Sun (1.4 million km diameter) were shrunk to the diameter of the 26m dish, Earth would be the size of a basketball and the Moon about the size of a tennis ball. On this scale, Earth would be 2.6 km away (roughly Cambridge) and the Moon would be 6.5m from the Earth. You can fit all the planets into the space between the Earth and the Moon. | + | If the Sun (1.4 million km diameter) were shrunk to the diameter of the 26m dish, (scaling is 53 million to 1) Earth would be the size of a basketball and the Moon about the size of a tennis ball. On this scale, Earth would be 2.6 km away (roughly Cambridge) and the Moon would be 6.5m from the Earth. You can fit all the planets into the space between the Earth and the Moon. |
