Scientists claim that a mysterious planet that destroyed life on Earth millions of years ago could do it again, with some believing it could happen as early as this month.

Planet Nine is a new planet discovered at the edge of the solar system in January which has triggered comet showers that bomb the Earth’s surface killing all life, says Daniel Whitmire, a retired professor of astrophysics now working as a math instructor.

The astrophysicist says the planet has a 20,000-year orbit around the sun and, at its closest to us, it knocks asteroids and comets toward Earth.

Moreover, fossil evidence has suggested that most life on Earth is mysteriously wiped out every 26 million to 27 million years, when Planet Nine passed through a distant Kuiper belt of comets, knocking comets into our solar system.

Whitmire claims that Planet Nine is responsible for the “extinction events”.

Conspiracy theorists in the ’80s and ’90s had claimed that a red dwarf planet called Nibiru or Nemesis, which orbits too close to Earth every 36,000 years, was behind the events.

And now some are convinced there will be a collision or a near miss before the end of April, as The Sun reports.

Nemesis or Nibiru was widely dismissed as crackpot pseudo-science — until Planet Nine was identified in January by the California Institute of Technology.
