What is the rotational period of Makemake?
Orbit and Rotation Makemake takes 305 Earth years to make one trip around the Sun. As Makemake orbits the Sun, it completes one rotation every 22 and a half hours, making its day length similar to Earth and Mars.

|Rotational Period:||3.915341 hours|
|Surface Temperature:||~ -241°C|
How often does Haumea rotate around the Sun?
As Haumea orbits the Sun, it completes one rotation every 4 hours, making it one of the fastest rotating large objects in our solar system. It is possible that a large object impacted Haumea billions of years ago and set off Haumea’s spin and created its moons. Haumea has two known moons: Namaka is the inner moon, and Hi’iaka is the outer moon.
What are the dimensions of the dwarf planet Haumea?
Haumea is an elongated object, unusual for a dwarf planet; its dimensions are about 2,322 × 1,704 × 1,138 km (1,443 × 1,059 × 707 miles). It has a fast rotation period of 3.92 hours, which may be the reason for Haumea’s elongation, and an orbital period of 285.46 years.
Particles in the ring are in a 3:1 resonance with the dwarf planet’s rotation; that is, ring particles make one revolution for every three times Haumea rotates. Haumea is the most distant solar system body with a ring and the only dwarf planet and Kuiper belt object to have one.
How is the mass of the Haumea system calculated?
Because Haumea has moons, the mass of the system can be calculated from their orbits using Kepler’s third law. The result is 4.2×1021 kg, 28% the mass of the Plutonian system and 6% that of the Moon. Nearly all of this mass is in Haumea.
