Planet Nine Might Not Be Responsible For Bizarre Orbits Of Distant Objects

In recent years, astronomer Mike Brown and others have suggested the gravity of an as-yet-undetected world - Planet Nine - is needed to explain the orbits of several of these distant bodies. "We can solve a lot of these problems by just taking into account that question".

Over the last few years, there's been growing evidence for a huge, ninth planet lurking on the very edges of the Solar System.

It's their collective gravity acting in concert that solves numerous puzzles posed thus far, Ann-Marie Madigan, a C.U. Boulder assistant professor and also author of the study, said.

"The picture we draw of the outer solar system in textbooks may have to change". On the mysterious and hypothetical celestial body that could be on the borders of the solar system, beyond the orbit of Neptune, everything has been said so far and the opposite of everything.

"He came into my office one day and says, 'I'm seeing some really cool stuff here, '" Madigan said. Fleisig, an undergraduate in astrophysics and his team of researchers suggest that perhaps a large singular body isn't what is causing the symptoms of Planet 9, but instead a large grouping of asteroids that are pulling on neighboring bodies.

According to CU Boulder, the team looked at one of these objects in particular - a dwarf planet called Sedna, which orbits the sun at a distance of almost eight billion miles and is distant enough so as not to be affected by Neptune's gravity, the Inquisitr previously reported - and tried to understand why its orbit looks the way it does.

Speaking at a meeting of the American Astronomical Society, Jacob Fleisig of the University of Colorado at Boulder presented a tantalizing new bit of research.

The natural process is that massive minor planets are naturally detached by the interaction of different gravities from the objects.


Madigan and team weren't exactly looking to explain the unusual orbits of these bodies, but when Jacob Fleisig, the lead author of the study, ran a series of simulations to study the dynamics of these bodies, they were totally surprised.

"You see a pileup of smaller objects to one side of the Sun. The smaller ones move faster than the larger ones; when the bodies crash, the orbits change in shape and orientation due to these small-scale interactions ".

These findings are supported by a 2012 study, which revealed that bigger "detached objects" tend to wander farther away from the sun, notes CU Boulder.

Planet Nine has not been confirmed, however, and all attempts to find it have been fruitless.

Remarkably, these relatively insignificant objects may also be culpable in the extinction of the dinosaurs.

Researchers at the University of Colorado Boulder started by developing computer simulations of the orbits of "detached objects" - distant dwarf planets like Sedna, as well as icy comets, moons and other bodies, that seem to be separated from the rest of the Solar System.

It's not impossible one of these caused the collision which wiped out the dinosaurs, the researchers said.
