Solar system's periphery could potentially encounter a newly discovered dwarf planet
In a recent finding shared by researchers at Princeton University on May 21, a new dwarf planet, 2017 OF201, has been discovered in the far reaches of the solar system. This discovery, however, challenges the idea of a hidden giant planet, known as Planet Nine or Planet X, in the solar system's outer edges.
2017 OF201, a suspected dwarf planet, is not the expected Planet Nine. Instead, it was discovered during the ongoing search for the elusive giant planet, which has been ongoing for about a decade. The mass of 2017 OF201 is about 2% of Pluto's, making it too big to be an asteroid but too small to be a full-fledged planet.
The orbit of 2017 OF201 is a huge, stretched-out oval with the sun near one end. Each trip it takes around the sun lasts more than 24,000 years. If 2017 OF201 is indeed pulled into a round shape by its gravity, it would qualify as a dwarf planet.
Cheng, an astrophysicist at Princeton's Institute for Advanced Study, is leading the team looking for more data to confirm 2017 OF201's dwarf planet status. Meanwhile, Cheng is also running more models to investigate how 2017 OF201's orbit might be influenced by other possible orbits for a Planet Nine.
The team's investigation using computer models suggests that 2017 OF201's orbit differs by about 90 degrees from the clustered orbits used to support the existence of Planet Nine. If 2017 OF201 doesn't fit with one of the proposed orbits for Planet Nine, it might be that Planet Nine takes a different path around the sun.
The discovery of 2017 OF201 challenges the notion of a hidden giant planet, but it doesn't completely rule out the possibility of Planet Nine. Different orbits for the potential giant planet are still being considered. The search for Planet Nine continues, with researchers investigating various possibilities to uncover the truth about this potential celestial body.
