Cameron and colleagues recently studied 27 exoplanets and found that one - third had
highly tilted orbits, including at least four that orbited backward.
Researchers used software to simulate the planetary motions within a two - planet system: one being a Jupiter - sized planet (depicted in the artist's concept above) orbiting its parent star at about the same distance Earth orbits the sun, and the other a large planet in
a highly tilted orbit that was slightly larger.
Previous research suggested that Planet Nine would possess
a highly tilted orbit compared with the relatively thin, flat zone in which the eight official planets circle the sun.
It is the first known object with a relatively circular but
highly tilted orbit beyond Neptune and Pluto.
Not exact matches
Because its
orbit is
highly inclined [
tilted with respect to the equator].
It's a weird planet, tipped way over (Earth is
tilted 23 degrees, while Pluto is canted at 122), and the
orbit is
highly elliptical and
tilted, too.
