For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

A potential new dwarf planet has been discovered in the outer reaches of the solar system, and its existence poses the ...

Studies of 15 M-type stars have revealed new insights into the potential presence of exoplanets. A new study led by ...

Size, Orbit, and Strange Movements. Scientists estimate that 2017 OF201 is slightly smaller than Ceres, the smallest known dwarf planet in our solar system, which is about 950 kilometers wide.

A team of astronomers believe they may have discovered a new dwarf planet—just like Pluto—on the edge of our solar system. The object—which orbits out beyond Neptune—has been named "2017 OF201" by the ...

Astronomers have announced the discovery of a new dwarf planet in our solar system, named 2017 OF201. Located far beyond Neptune, it orbits the sun every 25,000 years. Skip to main content ...

Earth has a newly-discovered neighbor in the solar system. But the heavenly body – possibly a dwarf planet à la Pluto – isn't a frequent visitor. Located beyond Neptune, its extreme orbit ...

Using a computational model of the binary’s evolution, the authors find that before the formation of the white dwarf, the closest distance between the two stars during their orbit was 1.3 au.

How many Earth-like exoplanets orbit M dwarf stars (Red dwarf stars), which are smaller and cooler than our Sun? This is what ...

According to a recently published arXiv pre-print, 2017 OF201 could soon join the ranks of Pluto and other dwarf planets in the solar system. The behavior of its extremely large orbit has piqued the ...

OF201, the object belongs to the same all-star family as Pluto: dwarf planets. Its diameter, roughly 435 miles (700 km), is half Pluto’s, ...
