(44594) 1999 OX3 is an eccentric

Jean-Marc Petit at Mauna Kea Observatories, Hawaii, United States.[5]

Orbit and classification

1999 OX3 orbits the Sun at a distance of 17.6–46.6 AU once every 181 years and 9 months (66,375 days). Its orbit has an eccentricity of 0.45 and an inclination of 3° with respect to the ecliptic.[1] The body's observation arc begins with its official discovery observation at Mauna Kea in 1999.[5]

semi-major axis of 30 AU and 1999 OX3 has a semi-major axis of 32 AU. The Minor Planet Center (MPC) does not classify this object as a centaur because the MPC defines centaurs as having a semi-major axis of less than 30.066 AU. 1999 OX3 crosses the orbits of both Neptune and Uranus and has an inclination of only 2.62°. The Deep Ecliptic Survey (DES) defines centaurs using a dynamical classification scheme, based on the behavior of orbital integrations over 10 million years. The DES defines centaurs as nonresonant objects whose osculating perihelia are less than the osculating semimajor axis of Neptune at any time during the integration. Using the dynamical definition of a centaur, 1999 OX3 is a centaur.[4]
