Ten Strong

The Solar System hasnt been the same since Pluto was downgraded from a planet to a dwarf planet, and all bets have been off since this monumental decision. Case in point, last year, scientists at the California Institute of Technology proposed that there might be a true Planet Ninein our solar system. The team asserted that it appears to be 10 times the mass of Earth and that it is hiding out in the remote recesses of our solar systemwell beyond the orbit of Pluto.

At the time of the discovery, Mike Brown, who was behind the work, noted that the existence of a 9th planet is extremely likely: Hey Planet Nine fans, a new eccentric KBO was discovered. And it is exactly where Planet Nine says it should be, Brown tweeted. Furthermore, he says, the new object takes the probability of this being a statistical fluke down to ~.001% or so.

Similar discoveries have been made in relation to new dwarf planets. Located about 13.7 billion km (8.5 billion miles) from the Sun, 2014 UZ224 measures about 530 km (330 miles) in diameter and takes around 1,100 Earth years to complete its orbit. And so, our littler corner of the cosmos has been in quite the state of flux.

Kathryn Volk and Renu Malhotra at the University of Arizona have noticed some strange movement out in the Kuiper beltmovement that they believe could suggest the existence of a tenth planet. To break this down a bit: Objects in the Kuiper belt are far enough away from the other major bodies in our solar system that the gravitational influence of the large planets doesnt impact them (at least, not to a measurable degree); however, their movements can still be predicted, thanks to sky surveys and a host of advanced technologies.

Notably, if these predictions dont match up, it may mean theres another objectanother large bodypast our vision whose gravity is impacting themovements of the Kuiper belt objects.

The search for Planet Ninehas lead scientists to believe that it is orbiting around700 AU from the Sun. However, Volk and Malhotra believe that this tenth planet could be much closer,as the orbit of Kuiper belt bodies shifted just beyond 50 AU. They also contend that the planet would be roughly comparable to Mars, in terms of size.

Other astronomers, however, are not so quick to hop on this train of thought. Alessandro Morbidelli at the Cte dAzur Observatory in Nice, France tellsNew Scientist I am dubious that a planet so close and so bright would have remained unnoticed.

Still, Volk is confident in these findings, which are set to be published in The Astronomical Journal. It would have to be quite a fluke for this to not be a real effect, she says. We think there is a real signal there and this implies an additional planet.

The discovery of more bodies in the Kuiper beltwill help to support or debunk these findings. Either way, our little solar family is going to continue to grow with these long-lost distant relations.
