Two More Outer Planets in our Solar System?

[bison]

Analysis of the motions of planets Uranus, and Neptune, dwarf planet Pluto, and of several Kuiper Belt Objects suggest that they may be pulled upon by one, or even two planets, farther out from the Sun. These suspected planets would be so far from the Sun that their detection would be difficult, even with the best telescopes.

A couple of large Kuiper Belt Objects have very eccentric orbits that come nearest the Sun where they cross the plane established by the other planets. This is thought to favor the theory that undiscovered planets are pulling on them, rather than other perturbing influences, such as a star that once passed close to our system, or even the gravity of our galaxy, as a whole.

and these two "theory" planets orbits which disturb the Kuiper belt and send objects towards the inner solar system at regular intervals as they coincide with these two planets orbits around the sun.

Interesting to speculate on the composition of these supposed planets of 2 to 15 times the mass of the Earth, and 500 to 1000 astronomical units from the Sun. To give a sense of the scale: Earth is one astronomical unit from the Sun, and Neptune, the outermost major planet, is at 30 AU.

These would presumably be frozen versions of Uranus and Neptune, as they would receive virtually no heat at such distances from the Sun. Hence, predominantly water, methane, and ammonia ices.

I'd image that with the ability of using telescopes to create an interferometer, that we should be able to image these planets somewhat, if we can only narrow down where to look. Hopefully they are not out of the elliptic, as that would make finding them a lot harder.

From what I have read in ancient texts, there are twelve planets, all which will be visible around the year 3020 AD. I'm not sure if Pluto is counted as a true planet.

My mistake, the above post does not belong in the science section.
