It is a member of the Pasiphae group. It has an average orbital distance of 24.1 million km, with an inclination of 144.7 degrees. Its period is 767 days.[2] It next comes to apojove (farthest distance from Jupiter) on 18 March 2026 when it will be 0.21 astronomical unit|AU (31 million km; 20 million mi) from Jupiter.[1]
