Something strange out there is still going on
Dr. Mike Brown, from Cal Tech, is probably the astronomer of our generation. He has established himself as a discoverer of new planets in our outer Solar System, mostly planets beyond Neptune. I listened to a lecture he gave recently. His predictions were astonishing.
He claims there are possibly 4 Earth Sized planets beyond Neptune and probably in extreme orbits. So far he has found five planets beyond Neptune in the same class as Pluto. That after years of no one finding new planets. These discovered planets are all small.
The reason is the astronomers have been looking in the wrong places. If you looked at the solar system sideways, it looks like a dish. They are all orbiting on the same angle to the Sun. Then came Pluto. It angles 20 degrees off. Plus it goes in a very odd orbit in as far as Neptune and way out into the belt. One planet is actually 45 degrees off the dish of the solar system. It has a comet like orbit. The orbit is 12,000 earth years long. It goes way out into space. Then it returns to the orbit of Neptune.
The belt of asteroids beyond Neptune is huge. It is full of different sized bodies. Statistically, there could be up to 10 planets the size of the Earth. Or none. We are still exploring. The orbits are all strange. The planets discovered so far have frozen nitrogen atmospheres. Some have frozen water on them. Several have orbiting moons.
The implication from the strange eliptical orbits is that something big came through here at one time or another. It could have been as small as the Earth. Or it might have been as large as Jupiter or even bigger. Some suggest a brown dwarf star went through. Where that body is now concerns all of us. If it was Earth-sized, where did it go? If it is bigger where is it now.
I suggest a computer analysis of the existing orbits. That should be a like a sign telling where the big body actually went to. Considering a big rock dragged them into the orbits they currently have. It should point in the right direction. It might point to a brown dwarf in a far orbit.
