Planet 9 may be "twisting" the solar system - Caltech research

BELGRADE - A planet, believed to be the ninth in our solar system, but which has remained mysteriously elusive to astronomers could be causing the "wobble" in our solar system that causes planets to move at a different angle to the sun, according to new research.

"Because Planet Nine is so massive and has an orbit tilted compared to the other planets, the solar system has no choice but to slowly twist out of alignment," lead author of the study from Caltech Elizabeth Bailey said in a statement.

All planets in our solar system (excluding the hypothetical Planet 9) move around the sun on the same plane, but this plane differs by six degrees to the sun which is tilted from Earth's perspective.

Planet 9, believed to be ten times the size of Earth, is theorised to orbit the sun at a distance 20 times farther than Neptune and at an even more extreme angle differing 30...
