Orbit[change | change source]
Sinope orbits Jupiter on a high eccentricity and high inclination retrograde orbit. The orbital elements are as of January 2000. They are changing a lot due to Solar and planetary perturbations. It is often believed to belong to the Pasiphaë group. However, given its mean inclination and different colour, Sinope could be also an independent object, captured independently, unrelated to the collision and break-up at the origin of the group. The diagram illustrates Sinope's orbital elements in relation to other moons of the group.
