The predominant colours of the bodies are blue (Earth), red (Mars) and grey (Moon). In the right half of each circle is the appearance of that body as it looks from space. In the left half is a typical scene from the surface of that body. Earth has a mass of about 6 thousand million billion tonnes and a diameter of about 12,700 kilometres. The diameter of Mars is 53% of our planet's, & it has a mass which is 11% of Earth's. The Earth is four times larger and 81 times heavier than the Moon.
