The candidate dwarf planet takes roughly 25,000 years to complete an orbit, which means it spends only about 1 per cent of its time close enough to Earth for us to detect it. “These things are ...

Astronomers have discovered a new pink dwarf planet that has the most distant orbit in our solar system. The discovery suggests there could be thousands of similar planets beyond the known edge of ...

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 ...

Science Search for 'Planet Nine' Yields Unexpected Discovery Less than 1% of this dwarf planet candidate's orbit is close enough to detect, which means astronomers are lucky to have caught it at all.

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.

Brown’s discovery of Eris, an icy world in the Kuiper Belt beyond Pluto, led to the reclassification of Pluto as a dwarf planet. He has been dubbed the “Pluto Killer.” ...

A potential new dwarf planet has been discovered in the outer reaches of the solar system, and its existence poses the greatest challenge yet to the hypothesis that a ninth planet lurks far from ...

While adding a dwarf planet to the roster of those already known is a coup, Dr. Gladman said, the survey's main goal is to establish precise orbits for a much larger set of objects, most of them ...

While 2012 VP113 and Sedna come closer, they don't trek as far out. The dwarf planet — only 300 kilometres in diameter — is believed to have an orbital period of 40,000 years.
