planet 9

As the only highly intelligent life form in the Solar System, humans have existed on Earth for 5 million years.

A mysterious planet may have approached the early Sun at a distance slightly farther than Uranus and rearranged everything in the star system.

Some astronomers have just hypothesized that the mysterious 9th planet in the Solar System may not be a planet, but actually a primitive black hole.

The Dark Energy Survey Project helps to shorten the search time and planet X can be accurately located at the end of this summer.
