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.

Image caption, 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.
