The quest for the mysterious Planet 9 continues, and recent findings suggest that there may be the “strongest statistical evidence yet” for the planet’s existence around one of the Solar System’s farthest points.
California Institute of Technology (Caltech) astronomer Konstantin Bogytin made the assertion to Andrew Gryphon at The Independent. Many of the earlier investigations on the possibility of a ninth planet have been attributed to Bogytin.
In this most recent study, Bogytin and associates monitored the motion of Trans-Neptunian Objects, or TNOs: different-sized celestial entities outside of Neptune’s orbit, such as Pluto and Eris, dwarf planets.
The researchers specifically examined TNOs that were previously disregarded due to their erratic motions brought on by Neptune’s gravity. Their routes are more difficult to understand because of this instability, but the researchers were up for the task.
The known forces from other planets, passing stars, and the galactic tide—the push and pull of the galaxy itself—were combined with this data and entered into simulations.
Two sets of simulations were performed: one with the assumption that Planet 9 is located where astronomers believe it to be, and the other with the assumption that it is not.
“Accounting for observational biases, our results reveal that the orbital architecture of this group of objects aligns closely with the predictions of the P9-inclusive model,” the authors of the report wrote.
On the other hand, if there were no Planet 9, it would be extremely improbable that these renegade TNOs would migrate. The planet’s existence appears to be the most consistent explanation for the observations we are making from space, at least for the time being.
However, the scientists acknowledge that they have yet to obtain solid evidence indicating the existence of Planet 9. Thus far, there have been unsuccessful attempts to identify it by examining its potential impacts on the other components of the Solar System.
The Planet 9 problem has a higher chance of being resolved if more potent telescopes come online, such as the Vera C. Rubin Observatory in Chile, which the study team stated.
The researchers stress that many of the estimations and assumptions contained in this study may be carefully evaluated once we have access to higher-resolution images of deep space, and they are eager to see what more research brings.
Remember that, according to the team’s estimates, a planet with the same characteristics as Planet 9 would still be rather tiny, with a mass of only five times that of Earth and a distance from the Sun that would be around 500 times greater than that of Earth.
Since Pluto is just 40 times further away than Earth, it would be nearly impossible to see it; therefore, we must now rely on simulations of things that we can detect to indicate Pluto’s presence.
“As importantly as the comparison with existing observations, the results presented herein offer a set of readily-falsifiable predictions, with near-term prospects for resolution,” the researchers write.
