'Metis', 'Callisto', and 'Sinope' are three of the satellites of which planet?
Sinope (moon) They are continuously changing due to solar and planetary perturbations. It is often believed to belong to the Pasiphae 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 satellites of the group. Sinope is also known to be in a secular resonance with Jupiter, similar to Pasiphae. However, Sinope can drop out of this resonance and has periods of both resonant and non-resonant behaviour in time scales of 10
9 Metis All three of these occultations fit the ellipsoid 222×182×130 km suggested by Baer. On March 7, 2014, Metis occulted the star HIP 78193 (magnitude 7.9) over parts of Europe and the Middle East. 9 Metis Metis (minor planet designation: 9 Metis) is one of the larger main-belt asteroids. It is composed of silicates and metallic nickel-iron, and may be the core remnant of a large asteroid that was destroyed by an ancient collision. Metis is estimated to contain just under half a percent of the total mass of the asteroid belt. Metis was discovered by Andrew Graham on 25 April
