Core Points - A potential dwarf planet named 2017 OF201 has been discovered beyond Neptune, challenging the existence of hypothetical celestial bodies like "Planet Nine" [1][2] - The discovery was made by researchers at Princeton University using data from the Victor M. Blanco Telescope in Chile, with 2017 OF201 having a diameter of approximately 700 kilometers, making it comparable to Pluto [1] - The orbit of 2017 OF201 is significantly distant, currently about 90.5 astronomical units (AU) from Earth, and it has a perihelion of 44.5 AU and an aphelion of 1600 AU [1][2] Group 1 - The orbit of 2017 OF201 does not conform to the patterns observed in other extreme trans-Neptunian objects (TNOs), which some researchers believe could indicate the presence of "Planet Nine" [2][3] - Simulations suggest that if "Planet Nine" exists, 2017 OF201 would be ejected from the solar system over millions of years, indicating that its existence does not support the hypothesis of "Planet Nine" [3] - The upcoming Vera C. Rubin Observatory in Chile is expected to enhance the search for similar celestial bodies, potentially providing more insights into the existence of "Planet Nine" [4]
