For more than 70 years, it was one of nine planets recognised in our Solar System, but it is now classed as a dwarf planet.
Take a journey through the planets and Pluto, with these images captured by the spacecrafts sent out to explore.
An enhanced image of Mercury shows the differences between the rock on the surface.
The surface of Venus is shown in a computer-generated picture based on images from the Magellan orbiter in the 1990s, with colours added using information from the Soviet Venera 13 and 14 landers.
The Earth, as seen by the crew of Apollo 11 in July 1969.

Jupiter, the largest of the planets, was captured by Hubble's Wide Field Camera Three.
Combined images taken by the Cassini spacecraft in May 2004 shows a wide view of Saturn.
Nasa's Voyager 2 spacecraft flew past Uranus, the seventh planet from the Sun, in January 1986.
Neptune, as seen from Voyager 2's camera. The picture was taken at a range of 4.4 million miles and shows the Great Dark Spot and its bright smudge.
The most detailed view of Pluto yet seen has been taken by the New Horizons spacecraft. The latest data has provided more information on the size of Pluto. It is a little bigger than expected, about 80km wider than previous predictions, making it around two-thirds the size of our moon.
