there may be another planet in our solar system it could be responsible for tilting the sun image credits: fotomanu_93/flickr . 




earlier this year an announcement raised a tantalizing possibility: a ninth planet lurking in the outer reaches of our solar system. 




the announcement turned the astronomy and planetary science world upside down. 




caltech astronomer michael brown and theoretical astrophysicist konstantin batygin found evidence for a possible 10 earth mass planet that may be tilting long-orbiting dwarf planets on their sides and shepherding them into clusters far past the orbit of neptune in highly eccentric orbits. in the last several months, more and more papers have been published about the possible planet and how it might prove an explanation for other strange things happening in our solar system. 




at a press conference held this afternoon, at the aas division of planetary sciences annual meeting in pasadena ca, another announcement was made about planet nine<u+2019>s effects on the spin-axis tilt of our sun. this time, the paper titled solar obliquity induced by planet nine is lead by caltech graduate student elizabeth bailey, with brown and batygin as co-authors.
