The celestial body's unusual orbit “implies that something extraordinary occurred" in the early days of the solar system—and ...

Astronomers first spotted Haumea far beyond the orbit of Pluto in 2003, and it was originally classified as a Kuiper Belt Objects (KBO). The dwarf planet's two moons, Hi'iaka and Namaka, were ...

Under this definition, then, Haumea isn't a dwarf planet. Of course the ring, the rapid rotation, and the odd shape of Haumea could all point to a possible impact.

Earlier this year, Haumea passed between Earth and a distant star, allowing planetary scientists to get a better idea of the dwarf planet's shape and size. The new findings were announced today ...

An artist's illustration showing dwarf planet Haumea with its newly discovered ring. IAA-CSIC/UHU The family of ringed bodies in the solar system has a new member: Haumea. The dwarf planet with an ...

Astronomers serendipitously found Haumea’s ring, described today in Nature, when they watched the dwarf planet briefly pass in front of a background star, blocking out the star’s light.Such a ...

Haumea is the fifth dwarf planet in the solar system along with Pluto, Ceres, Eris and Makemake. Its existence was confirmed in 2005, when it was called 2003 EL61 ...

This week, researchers revealed that the egg-shaped dwarf planet Haumea — one of four known diminutive planets that circle the sun from beyond the orbit of Neptune — is surrounded by a ring of ...

The dwarf planet Haumea has a similar history, as it is joined in its orbit by two satellites that are thought to have been created by impacts with it in the past. During these impacts, parts of ...

The planet, dubbed Haumea, orbits the Sun far beyond Neptune—the eighth and furthest recognised "full" planet in our star system since Pluto was downgraded to dwarf status in 2006.

When Haumea passed in front of a star called URAT1 533-182543 on January 21 of this year, scientists were able to view the dwarf planet with 12 telescopes from ten different labs.

The fifth dwarf planet of the Solar System, Haumea, and at least one of its two satellites, are covered in crystalline water-ice due to the tidal forces between them and the heat of radiogenic ...
