Order of the planets
The planets in our solar system are usually ordered by their distance from the Sun, with Mercury being the closest.
Half of the eight planets are known as the terrestrial, or inner, planets – with Mercury being closest to the Sun, followed by Venus, Earth, and then Mars.
The other half are the Jovian, or Jupiter-like planets. In order of distance from the Sun, these are Jupiter, Saturn, Uranus, and Neptune.
