The orbit of 2017 OF201 is a tale of gravitational dynamics. Its perihelion at 44.9 AU puts it close to Pluto’s territory, but its aphelion pushes it out into the zone where the Sun’s force ...

2017 OF201’s elongated orbit makes it an outlier from the clustered objects, but Yang’s calculations suggest that the orbit of 2017 OF201 should remain stable over roughly the next billion years.

2017 OF201 is about one-third the size of Pluto, which was reclassified as a dwarf planet in August 2006, and "is likely large enough to qualify as a dwarf planet, and its orbit is extremely wide ...

Temporarily named 2017 OF201, it takes more than 24,000 years to travel around the sun just once along a highly elliptical orbit, coming as close as 4.2 billion miles and moving as far out as 151 ...

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 ...

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 ...

So-called "trans-Neptunian objects" (TNOs) like 2017 OF201 can vary dramatically in size—from as large as 1,477 miles in diameter (i.e. Pluto) down to just 22 miles like the peanut-shaped Arrokoth.

If there were one, that Planet Nine would "nudge the closest part of 2017 OF201's trajectory inward until Neptune flung it out of the solar system." Because 2017 OF201 is there, that could be an ...

That makes 2017 OF201 almost 30 times farther out than Neptune at its most distant point. This kind of orbit earns the object a spot in the category of extreme trans-Neptunian objects (ETNOs).

But 2017 OF201 is superlative even among the distant TNOs; its orbit takes it as far as 838 astronomical units from the Sun—making it nearly 30 times farther than Neptune, which again, is itself ...
