Dwarf Planet Facts

There are five official dwarf planets in our solar system with another four objects that almost certainly are. There are 394 objects in the solar system that are possible dwarf planets including the five currently recognised.

The known dwarf planets are Ceres, Pluto, Haumea, Makemake and Eris. These bodies are each over appropriately 950 km in diameter.

All the dwarf planets are found in the Kuiper Belt with the exception of Ceres which is found in the asteroid belt.

No dwarf planets have been visited by space probes, though in 2015 NASA’s Dawn and New Horizons missions will reach Ceres and Pluto respectively.
