Inner solar system. Artwork of the four planets of the inner solar system orbiting the Sun. The orbits of the planets and the moons are shown as blue lines. The relative distances from the Sun and relative planetary sizes are to scale,but the planets would not be visible on this scale. The planets (and the time taken to orbit the Sun),in their order from the Sun,are: Mercury (88 days),Venus (224 days),Earth (365 days),and Mars (687 days). Earth has one moon,and Mars has two,while Mercury and Venus do not have any moons. The Sun is one of billions of stars in the Milky Way galaxy (the bright band in the background) | |
