The dwarf planet's orbit is such an elongated ellipse that it takes around 25,000 years to make one orbit of our sun. At its closest, it sits approximately 6.66 billion kilometers away from the sun.

How this world got to the edge of the solar system is a mystery — perhaps the result of close encounters with a giant planet like Jupiter or Neptune that tossed it out into a wide orbit. Or ...

A dwarf planet thought to have some ice mixed in with its dirty surface may have a lot more cool than we ever expected. Ceres – the largest body in the asteroid belt between Mars and Jupiter ...

The scientists announced in a news release that they have found a trans-Neptune Object (TNO), code-named 2017OF201, located past the icy and desolate region of the Kuplier Belt.

A planet far, far away A possible dwarf planet, like Pluto, has been observed in our solar system, according to a preprint published in arXiv. The area of space where this planet was found was ...

But the heavenly body – possibly a dwarf planet à la Pluto – isn't a frequent visitor. Located beyond Neptune, its extreme orbit circumnavigates the sun once every 25,000 years, taking it ...

Scientists at the Institute for Advanced Study in Princeton, New Jersey, discover a new trans-Neptune Object, 2017OF201, potentially discrediting 2016 theory of Planet Nine.

The dwarf planet candidate’s closest point to the sun is about 7 billion kilometers, roughly 45 times that of Earth’s distance. One trip around the sun takes more than 24,000 years.
