What is the planet Haumea made of?
rock
As a result it is believed that Haumea is made up entirely out of rock covered by a thin icy shell. It is also one of the densest Kuiper belt objects, with a density of 1.885 grams per cubic centimeter thus covering the values for silicate minerals such as olivine and pyroxene.
Is Haumea a gas or rock planet?
It takes 285 Earth years for Haumea to make one trip around the Sun. This dwarf planet has a mass less than half that of Pluto. It is believed to be solid rock covered in an icy crust.
What is makemake made of?
Composition and Surface: With an estimated mean density of 1.4–3.2 g/cm³, Makemake is believed to be differentiated between an icy surface and a rocky core. Like Pluto and Eris, the surface ice is believed to be composed largely of frozen methane (CH4) and ethane (C2H6).
Does Haumea have rings?
Rings. Haumea is the first known Kuiper Belt Object to have rings. Scientists announced the discovery in 2017 after watching the dwarf planet pass in front of a star.
Does Haumea have a core?
The core is surrounded by an icy mantle that ranges in thickness from about 70 at the poles to 170 km along its longest axis, comprising up to 17% of Haumea’s mass. Haumea’s mean density is estimated at ≈ 2.018 g/cm3, with an albedo of ≈ 0.66.
What is Haumea mass?

How did Haumea get its rings?
Scientists think they formed from a collision between Haumea and another rocky body in the distant past. This collision would also account for Haumea’s fast spin rate. It might also account for the rings. At one time, Saturn was the only body in the solar system known to have rings.

What does the name Haumea mean?
Origin and Meaning of Haumea. According to a user from Oregon, United States, the name Haumea is of Hawaiian origin and means “Goddess of fertility and childbirth”.
What does the planet Haumea name mean?
The goddess of fertility and childbirth . A dwarf planet in the Kuiper belt, roughly one-third the mass of Pluto. In Hawaiian mythology, Haumea is the goddess of fertility and childbirth. She is the mother of Pele, Kāne Milohai, Kā-moho-aliʻi, Nāmakaokaha’i, Kapo and HiʻiakaikapolioPele.
What are the names of Haumea’s moons?
The outer Solar System dwarf planet Haumea has two known moons, Hiʻiaka and Namaka, named after Hawaiian goddesses. These small moons were discovered in 2005, from observations of Haumea made at the large telescopes of the W. M. Keck Observatory in Hawaii. Haumea’s moons are unusual in a number of ways.
What is Haumea trailed by?
The plutoid Haumea is trailed by a swarm of small, icy bodies that once were part of it. Haumea also has a distinctive spin and shape. It rotates once every four hours—six times faster than Earth does. That’s the fastest spin rate of any major object in the solar system.
