Surrounding Haumea: Pluto's Pecular Neighbor

Stay away from our hot stars, away from our distant horizons forever in the dusk, with a belt of icy frozen objects. Beyond the orbit of the deep blue banded ice giant Neptune, Neptune is the most distant known major planet in our sun - countless strange objects of ice and rock dance in the dark. This remote area - called from

Among these four, Haumea stands out from the crowd and becomes the most fascinating and dazzling little world with its extremely slender shape and fast rotation speed. In October 2017, an international team of scientists led by astronomers at the Andulusia [Spain] Institute of Astrophysics published a study in the journal. from

"We predict that on January 21, 2017, Haumea will pass in front of a star, and twelve telescopes from ten different European observatories will converge on the dwarf planet Haumea. We are surprised to find it is significantly larger, Less reflection than previously thought. Jose Luis Ortiz on October 11, 2017 from

Haumea is a fascinating object. This is because it rotates around our sun in an elliptical orbit and takes years to complete. At the time of this writing, it is located at 50 from

 The average distance between the Earth and the Sun is about 93,000,000 miles. In our own solar system, Haumea also takes about 3.9 hours to rotate on its axis, far more than any other body, more than a hundred kilometers in length. This rotation speed flattens it - which means that its ellipsoid shape has been compared to football. According to recent data, Haumea measured 2,320 kilometers on its largest axis - almost the same as Pluto - but it does not have a global atmosphere like Pluto. The quality of Haumea is also about one-third that of Pluto, only 1/1400 of our planet.

Twilight beyond Neptune

Two groups of astronomers claimed to have discovered Haumea. In December 2004, Dr. Michael Brown and his team at the California Institute of Technology [Caltech Institute of Technology] in Pasadena, California, discovered the image of Haumea on June 6, 2004. On July 20, 2005, they released an online summary that they plan to publish a report at a meeting in September 2005 to announce the discovery.

 It is a dwarf planet located outside the orbit of Neptune. Haumea is classified as a dwarf planet because it is considered large enough to be rounded into a hydrostatic shape by its own gravity, but not enough to clear a simple-sized object near it.

Haumea's slender shape, along with its high density, high reflectivity [produced by the bright surface of crystal water ice] and rapid rotation, are considered to be the result of a huge catastrophic collision that occurred long ago. This devastating collision is resolved when Haumea becomes the largest member of the apparent series of collision objects. This family includes several other big families. from

 From our star. Haumea's orbit is slightly larger than the orbital eccentricity of any other member of its collision group, which is believed to be the result of Haumea's 7:12 weak orbit resonance with Neptune - which has been gradually modified from its original orbit for a billion years.

Haumea is also the third brightest resident in the distance from

 After Pluto and Makemake, it can be easily seen with a large amateur telescope. It also shows large fluctuations in its brightness over a period of 3 to 9 hours, which can only be explained by the rotation period during this time. This is faster than any other known balancing object in our solar system, and it is indeed faster than any other known object larger than 100 kilometers in diameter. Although most balanced rotating bodies are flattened into oblate spheroids, Haumea stands out in the crowd because it rotates so fast that it is converted into a triaxial ellipsoid. If Haamea rotates faster, it will become a dumbbell shape and split into two different parts. This rapid rotational speed is thought to be due to the effects of the formation of two small satellites and other members of the collision family.

After Pluto was discovered in 1930, many astronomers began to suspect that it was not living alone in the darkness of our solar system, deep freezing. For example, in 1930, American astronomer Armin O. Leuschner [1868-1953] proposed that Pluto "may be one of many long-period planetary objects that have not yet been discovered."
