Astronomers claim that they have found new evidence of a ninth planet hidden in our solar system.

They had been looking for enough evidence that this Planet Nine also known as Planet X — existed for years. However, a new line of evidence supporting the existence” of the planet, thought to be circling the Sun in an orbit behind Neptune, has now been discovered.

For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar system is best explained by another, undiscovered planet. That helps explain the orbits of objects that lie at the very far reaches of our solar system, more than 250 times away from the Sun than we are.

Now Konstantin Bogytin, an astronomer who helped popularise the theory, said that he and his team have found yet more evidence that suggests that the planet exists. He said “We have the strongest statistical evidence that Planet 9 is out there’.

The new evidence shows that those objects that have their movement made unstable because they interact with the orbit of Neptune. That instability meant they were harder to understand, so typically astronomers looking at a possible Planet Nine have avoided using them in their analysis.

The team of astronomers carried out a host of simulations to understand how those objects’ orbits were affected by various things, including the massive planets around them such as Neptune, the “Galactic tide” that comes from the Milky Way, and passing by stars.

Dr Bogytin said, ‘The best explanation was from the model that included Planet Nine, however, They noted that there were other explanations for the behaviour of those objects – including the suggestion that other planets once influenced their orbit, but have since been removed – but claim that the theory of Planet Nine remains the best explanation.
