Solid evidence for a 9th planet, say Caltech astronomers | EarthSky.org

This is actually a little bit creepy since various people have said it was out there for years and that it could have an influence on Earth’s various cycles.

If it exists, the 9th planet has 10 times the mass of Earth – orbits 20 times farther from the sun than Neptune – and takes 20,000 years to orbit the sun once.

  1. 20,000 years to orbit the sun! Can you imagine? If this planet actually exists, I wonder what sort of effect it has on the rest of our solar system.

    • That is what is kind of spooky. Seems like our climate might have a cycle in that time range. Looking at its orbit, there are times when it’s much closer to Earth. I’ve read about the possibility of another massive planet out there that causes problems and this might be it.

      • That would make sense. I’ve heard that planets can have elliptical (is that the correct word for oval?) orbits… and I’ve also heard that the Earth has some very long cycles of hot/cold, not to mention that the magnetic poles can switch …. sounds scary, but if Pangea was originally one land mass, that broke up and the energy/momentum of that breakup is what made the mountains, then something scary must have caused it.

      • Exactly. Plate tectonics alone wouldn’t do it. Yes, all orbits are elliptical. In fact, a circle is a special case of an ellipse. An ellipse has two focii which are coincident in a circle. Kepler discovered that planetary orbits were ellipses with the Sun at one focus which was the key to accurate predictions regarding where the planets would be at a given time. Kepler, like numerous other early astronomers, was an astrologer who wanted more accurate data.
