This year, a pair of astronomers announced they had found evidence that another, massive planet may exist in the outer solar system. This would be a planet roughly 10 times the mass of Earth. That makes it something like Neptune in size. Big.

It orbits our Sun on a tipped, elliptical path. It never gets closer to the Sun than 30 billion kilometers. That is out there.

When I first read about it, I thought “Maybe this is Planet X.”

Back in the early 1900s, astronomer Percival Lowell starting search for a planet beyond Neptune. For years, he studied the sky from his observatory in Arizona  looking for that planet. He never found it, but his calculations helped other astronomers find Pluto in 1930.

Planet X (also known as Niribu)  is a planet that some people have believed is in our solar system, even though scientists have said it’s not. You might say that believers in Planet X are also “out there” like this new planet. Believers claimed it was not only out there, but possibly inhabited. They claim it is on a huge 3,600-year orbit.

That orbit brought it into our inner solar system enough times to deliver literally Biblical catastrophes to little Earth.

In 2003, a cult following Niribu got some attention in the media until their critical May 15, 2003 date for the appearance of Planet X passed without an appearance.

The Mayan special date of December 21, 2012 (which I covered with some unserious seriousness on this blog) also passed by quietly and Nibiru was slated to crash into Earth that day which was the winter solstice. (Though I still say that the Mayan calendar was misinterpreted and was never meant to indicate the “end of the world.”)

One of the astronomers who discovered this new planet was Mike Brown who was also one of the party-poopers who helped get Pluto demoted to less than planet status. (PlutoKiller‘s team discovered Eris, a large object roughly the same size as Pluto and that discovery eventually led to the International Astronomical Union’s demotion.

Of course, this new planet is not going to be demoted, because it is very big. It would become the new ninth planet. It is a tricky call on this one because to say the planet was “discovered” when no one has seen it (even in a big telescope) is a bit of a reach.  Like other things in science, including most things that Albert Einstein was famous for, we have some evidence that something exists or is possible, but we don’t actually have it. Think about all that searching for the Higgs boson particle which was “confirmed” in 2013.

People haven’t given up on Planet X or Niribu. There are still “predictions” of disaster connected to it. And NASA has checked in to say that although their WISE survey found thousands of new stars, but no Planet X – but maybe a “Planet 9.” (Not to be confused with the wonderfully, terrible film Plan 9 From Outer Space)
