What Are The Dwarf Planets In Our Solar System

Makemake was the last of the dwarf planets to be discovered.

Haumea and makemake are the most recently named dwarf planets in the solar system. Ceres is the closest dwarf planet to the sun and lies between mars and jupiter in the region of the asteroid belt. With the exception of ceres which is located in the asteroid belt the other dwarf planets are found in the outer solar system. The international astronomical union iau notes five in particular.

The half dozen largest candidates have at least one known moon allowing determination of their masses and an estimate of their densities. The number of dwarf planets in the solar system is unknown. There are 5 officially recognised dwarf planets in our solar system they are ceres pluto haumea makemake and eris. At most 10 among bodies known so far.

However consideration of the surprisingly low densities of many dwarf planet candidates suggests that the numbers may be much lower e g. Ceres is located inside the asteroid belt between the orbits of mars and jupiter while the other dwarf planets are located in the outer solar system in or near to the kuiper belt.

Pluto and all the other dwarf planets except ceres and sedna are located in the kuiper belt. Scientists found it shortly after easter in 2005 and nicknamed it easterbunny its official name comes from the rapa nui fertility god. The prototype dwarf planet is pluto. The number of dwarf planets in the solar system is unknown as determining whether a body is in hydrostatic equilibrium requires close observation.

Estimates have run as high as 200 in the kuiper belt and over 10 000 in the region beyond. The rapa nui are the native people of easter island you may know it from its giant stone statues which brings the story full circle. It is composed of rock and ice and is 950 km 590 mi in diameter. Haumea is unique because of its ellipsoid shape only just meeting the hydrostatic equilibrium criteria for dwarf.
