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 ...

In fact, there are several objects out there with even more elongated orbits than Neptune and our outer planets. This is why the existence of Planet Nine has always been such a hot topic among ...

A possible new dwarf planet has been discovered at the edge of our solar system, so far-flung that it takes around 25,000 years to complete one orbit around the sun. The object, known as 2017 ...

But 2017 OF201’s path contrasts with the clustered orbits used to support the existence of Planet Nine. “The orientation seems to be … 90 degrees, probably, of the cluster,” Cheng says.

In the meantime, Cheng said he hasn’t given up searching for Planet Nine. The new discovery, however, may throw a wrench into some long-standing theories of the planet’s existence.

Last month, a U.S.-based trio hunting the elusive "Planet Nine" said they instead stumbled on what appears to be a new dwarf planet in the solar system's outer reaches.

Simulations Of Early Solar Systems Find Up To 40 Percent Chance That Planet Nine Exists Wide-orbit planets are fairly common according to the study, and there's a good chance we have one of our own.

The planet also interests scientists because it is strangely cold. Most of the gas giants discovered outside our solar system so far have been what are known as "hot Jupiters," where temperatures ...
