And while you’ve likely heard of Pluto — the most famous member of the Kuiper Belt — you’re probably not as familiar with the second most famous object, the spinning dwarf planet Haumea. Scientists ...

For example, most dwarf planets are smaller than our moon and, except for Haumea, no dwarf planet is known to have rings. Days on dwarf planets vary, as do the number of moons. For example ...

Even with the new result, Ragozzine emphasized that both Pluto and Haumea moon systems have the planetary science community stumped. “There is no self-consistent formation hypothesis for either ...

Within our programme of physical characterization of trans-Neptunian objects (TNOs), we predicted an occultation of the star URAT1 533−182543 by the dwarf planet (136108) Haumea and arranged ...

Astronomers have made an unexpected discovery about Haumea, a mysterious dwarf planet on the edge of our solar system. It has a ring around it. Until now, such rings had only been found around the ...

"By taking advantage of good fortune, good alignment with Haumea and the background stars, we can do some of that work without it being up close and personal," he said.

Haumea spins so fast that its shape is more football-like than round. If you've never heard of the dwarf planet Haumea, tonight's a pretty good night to become familiar with the football-shaped ...

Most objects with a radius over 200 miles are spherical, but Haumea is an exception ... into this completely football egg shape. It has no choice. It has to be that shape.

The light curves show deep drops caused by Haumea passing in front of the background star. Because the drops are abrupt, Haumea must lack a global atmosphere, such as the one on Pluto. In addition ...

That was all enough to make Haumea an interesting TNO, but then a chance orbital encounter in 2017 made Haumea downright fascinating. Haumea passed in front of a bright star called URAT1 533-182543.
