There may be a 9th planet after all

Scientists Find Hints Of A Giant, Hidden Planet In Our Solar System

The astronomer whose work helped kick Pluto out of the pantheon of planets says he has good reason to believe there's an undiscovered planet bigger than Earth lurking in the distant reaches of our solar system.

Here is Caltech's release...
http://www.caltech.edu/news/caltech-res ... anet-49523

Konstantin Batygin and Mike Brown used simulations and modeling to reach their conclusion that the protoplanetary disk from which our Solar System developed generated five large planetary cores, not four. The pertinent paper is titled "Evidence for a Distant Giant Planet in the Solar System".

I don't believe this planet has been spotted optically yet. If this planet is anywhere near perihelion many telescopes on Earth could locate it. Anyone up for a hunt?

I found the link to the publication Mike Brown and Konstantin Batygin released in the Astronomical Journal: http://iopscience.iop.org/article/10.38 ... 6/151/2/22

This website gives a more basic explanation of the information: http://aasnova.org/2016/01/20/a-ninth-p ... ar-system/

Apparently the planet is the likely culprit in the disruption of many Kuiper Belt Object Orbits pulling them further out. It hasn't been sighted optically yet, but they are hopeful it will be spotted within 5 years.

NASA's Planetary Science director Jim Greene offers a cautious perspective about jumping on the bandwagon too soon with this discovery, yet provides an optimistic outlook at how this is a great opportunity to show the public just how the scientific process works. With the media fiasco regarding LIGO's potential discovery still fresh in everyone's mind I think that the science community should lead with this approach.

NASA's Solar System Exploration section has reprinted the Caltech release. I think it's verbatim, but just in case...

I am not sure at this time whether the Highland Road Park Observatory's 20OGS and/or 16OGS will join in the search.

The evidence for a ninth planet so far gathered at that time will be presented to the public at the Highland Road Park Observatory on 12 February at 7:30pm. The presentation has no admission fee and is aimed at a general adult audience.
