Back in January, the astronomer who led the charge to have Pluto demoted to dwarf planet status announced that he’d just found evidence that a huge, icy planet could be lurking on the edge of the Solar System, just past Neptune.
Mike Brown, a planetary astronomer at Caltech University, estimated that the hypothetical ‘Planet Nine’ appears to be circling the Sun on a super-elongated orbit that takes an incredible 10,000 to 20,000 years to complete. And now, thanks to a newly detected Kuiper Belt Object (KBO) that’s acting really strange, Brown says the case for Planet Nine just got a whole lot stronger.
“Hey Planet Nine fans, a new eccentric KBO was discovered. And it is exactly where Planet Nine says it should be,” Brown tweeted over the weekend.
