Astronomers have discovered a dwarf planet in the Solar system ring

Astronomers discovered the first-known "egg" that later became an official dwarf planet, called "Haumea" to have unexpected thin ring-like bands made up of particles and debris, circling around it.

The discovery, led by astronomer Jose Luis Ortiz from the Instituto de Astrofísica de Andalucía in Spain, took more than a little coordination to pull off.

They say the dwarf planet has an unusual elongated ellipsoid shape, with axes of approximately 2,322 kilometres (1,442 miles) by 1,704 kilometres (1,059 miles) by 1,138 kilometres (707 miles), and no global atmosphere that can be detected.

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

The occultation also provided the team with our best analysis yet of Haumea's size and shape, which the researchers describe as "very exotic". Jose Ortiz of the Institute of Astrophysics of Andalusia in Spain said that it is regrettable that even with the most enormous telescopes on Earth, or the Hubble Space Telescope, we can not see the details of Haumea, than a dot of light. They got 10 Earth-based observatories ready, and on that night all pointed their telescopes towards the same patch of sky to learn as much as they could. "The authors' results suggest that Haumea might not be in hydrostatic equilibrium, and this touches on the still-sensitive topic of how planets and dwarf planets should be defined", writes Amanda Sickafoose, an astronomer at MIT, in an accompanying article also published in Nature today. It has two known moons: "Hiʻiaka and Namaka". But it's too soon to say for sure whether Haumea really doesn't match up to this criteria.

This discovery marks the first time anyone has ever found rings around an object in the Kuiper belt- a region of icy bodies out beyond the Neptune orbit.

Width of the ring of the dwarf planet Haumea is located 70 km radius - 2287 km. And we don't yet know how common features like it are either.

In addition to the rings found around Chariklo, there's also evidence of a similar phenomenon around another Centaur called Chiron, although it's less clear than the Chariklo ring.
