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 ...

The object, known as 2017 OF201, was found by researchers at the Institute for Advanced Study and Princeton University who were searching for “Planet Nine,” a hypothetical planet larger than Earth ...

As it orbits the sun once every 25,000 years, the celestial body 2017 OF201 travels beyond the Kuiper Belt into a region thought to be largely devoid of objects ...

Scientists may have discovered a dwarf planet far beyond Neptune — an unearthing that may disprove a longstanding theory ...

Astronomers have uncovered a distant celestial body that may be a new dwarf planet, orbiting the Sun from more than twice the distance of Pluto. Found by researchers at the Institute for Advanced ...

The object, known as 2017 OF201, was found by researchers at the Institute for Advanced Study and Princeton University who were searching for “Planet Nine,” a hypothetical planet larger than ...

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.

Named 2017 OF201, its diameter is about 435 miles (700 km) The object takes roughly 25,000 years to orbit the sun It is among the solar system's furthest visible objects Scientists have identified an ...

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

Astronomers have cataloged a frozen minor planet called 2017 OF201, and while it might not be the elusive ninth planet that some have posited exists, its unusual orbit has scientists paying close ...

This icy world, temporarily named 2017 OF201, could be a distant cousin of Pluto — and scientists mean "distant" quite literally. At its farthest point, it's more than 1,600 times the distance ...

The Kuiper Belt is populated by numerous icy bodies. Given the name 2017 OF201, the object falls into a category called trans-Neptunian objects that orbit the sun at a distance beyond that of Neptune.
