It moves around the Sun at an average distance of 45.8 AUs in a mildly eccentric orbit (e ~ 0.16) and a relatively high inclination of 29.0 degrees, that takes nearly 310 years to complete. (solstation.com)
Somewhat smaller than Eris and Pluto, it orbits the Sun at an average distance of 46 AUs at a relatively high inclination. (solstation.com)
That high inclination means it goes very high to the north and very far to the south as it goes over the Earth. (scientificamerican.com)
