Shall we be celebrating the inclusion of another planet in our solar system soon?

A famous astronomer said he was able to track the movements of the so-called "Planet 9" through the Kuiper Belt, a band of asteroids and comets encircling the solar system.

Mike Brown, the space scientist who first discovered the existence of this supposed ninth planet, posted on Twitter a graph summarising his observations of the Kuiper Belt, which he said will provide solid proof that Planet 9 indeed exists.

"Hey Planet Nine fans, a new eccentric KBO was discovered. And it is exactly where Planet Nine says it should be," Brown said on his Twitter account, with the accompanying graph.

The celebrated astronomer, as quoted by The Mirror, seemed very convinced by his findings pointing to Planet 9's actual existence, even saying that the chances of his observations being a "statistical fluke" was about 0.001 percent.

"Planet Nine, by the way, is oriented oppositely to these objects, so it's to the right and way up off the plot," he explained further.

Brown brought some exciting news to space enthusiasts last year, when he first announced his findings supporting the idea of another planet lurking around our solar system.

Not everyone, however, was convinced by the space scientist's discovery and the supposed evidence he is using to support it.

For instance, Ann-Marie Madigan, a postdoctoral researcher at the University of California, has completely shut the doors on the idea that there is another planet in the solar system.

Madigan said Brown's observations do not point to Planet 9, but only dwarf planets or massive asteroids typically moving around the Kuiper Belt.

"We should have a new Kuiper Belt that's far more massive than the current-day Kuiper Belt, at larger distances," she said in a talk before the SETI Institute, as also quoted by The Mirror.
