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.
Dwarf planet Haumea is a member of a group of objects that orbit in a disc-like zone beyond the orbit of Neptune called the Kuiper Belt. This distant realm is populated with thousands of miniature icy worlds which formed early in the history of our solar system about 4.5 billion years ago.
Haumea (minor-planet designation: 136108 Haumea) is a dwarf planet located beyond Neptune's orbit. [25] It was discovered in 2004 by a team headed by Mike Brown of Caltech at the Palomar Observatory , and formally announced in 2005 by a team headed by José Luis Ortiz Moreno at the Sierra Nevada Observatory in Spain , who had discovered it that ...
Haumea or the Haumean family is the only identified trans-Neptunian collisional family. Detailed studies of the visible and near infrared spectrum show it is a homogenous surface covered by a mixture of amorphous and crystalline ice, and about 8% organics.
Haumea’s characteristic extreme elongation is probably caused by its rotation, which is so rapid it turned it into an ellipsoid. Its rotational speed as well as its collisional origin also make Haumea one of the densest dwarf planets discovered to date.
Haumea is a dwarf planet located beyond Neptune in the Kepuir Belt. Its rotation is the fastest in the solar system as it completes it in just 4 hours. It has a ring that orbits around it and is an elongated ellipsoid.
Haumea is a dwarf planet located in the Kuiper Belt beyond Neptune’s orbit. It was discovered in 2004 by a team led by Mike Brown at Caltech’s Palomar Observatory. Haumea measures 1,960 km in length and has two known moons, Namaka and Hi’iaka.
Haumea, unusual dwarf planet orbiting the Sun in the Kuiper belt beyond Pluto. It was discovered in 2003 by a team of American astronomers at Cerro Tololo Inter-American Observatory. Originally called 2003 EL61, Haumea is named for the Hawaiian goddess of birth and fertility.
Discovered in 2004, Haumea was classified as a dwarf planet that orbits beyond Neptune in the Kuiper Belt. It's unique for it's fluctuating brightness due in part to its high rotation rate of only 4 hours which has resulted in it becoming distorted into a triaxial ellipsoid!
Haumea appears to be unique among large solar system objects in having such a distinctly nonaxisymmetric, triaxial ellipsoid shape. Based on its rapid rotation (angular velocity ω = 4.457 × 10 −4 s −1), Haumea is inferred to have assumed a particular shape known as a Jacobi ellipsoid.
Haumea today is not spinning fast enough to allow this, but it must have been spinning much faster in the past, and slowed down, due to two effects: 1) loss of angular momentum by ejection of the family members; and 2) changes in its moment of inertia.
Why is Haumea Shaped Like an Egg? Most objects with a radius over 200 miles are spherical, but Haumea is an exception.
In this paper, we attempt to reconcile the existing data from Haumeas light curve and occultation ’ shadow, with the goal of deriving its true shape and internal structure. Besides its axes, important quantities to constrain are the ice fraction on Haumea today and the size, shape, and density of its core.
Why is Haumea Shaped Like an Egg? Haumea is one of the fastest rotating large objects in our solar system. A single day on the dwarf planet is only about 4 Earth hours long.
Haumea is the first body outside the population of Centaurs that has a ring. The discovery shows that the presence of rings could be more common than was previously thought, in our Solar System as well as in other planetary systems.
The 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.
Haumea (Hawaiian: [həuˈmɛjə]) is the goddess of fertility and childbirth in Hawaiian mythology. She is the mother of many important deities, such as Pele, Kāne Milohai, Kāmohoaliʻi, Nāmaka, Kapo, and Hiʻiaka.
If Haumea were to rotate much more rapidly, it would distort itself into a dumbbell shape and split in two. Another writeup suggests: Haumea has this egg- shape due to a collision that took place a long time ago, which made it spin really fast. Its shape is unique amongst the other dwarf planets.
I keep reading that Haumea spins the fastest of any planet (or dwarf planet) in the solar system. It's so fast it's been squashed into an elipsoid. But I can't find a figure on how fast it spins. (Its orbit round the Sun is commonly known, but not its rotation speed).
How does Gravity Work on Haumea? I have a question about the Trans-Neptunian object Haumea. This dwarf planet is very unique because it has such a short rotational period that it is stretched by centrifugal force into a football shape!
