“Ninth planet in our solar system” Speaker – Kat Volk
There is intriguing evidence for a ninth planet in our solar system says Kat Volk, a post-doctoral researcher in the UA Department of Planetary on this project. If planet nine were to exist, it would have a huge impact on the study of the solar system. The planet is thought to be about 20 times further from Earth than Neptune, the farthest large planet we now know of. The Hypothetical planet would have an orbital period of 665 AU, then the most distant objects would be in simple mean motion resonances with it, Volk said.
