Cannibalistic Jupiter gobbled up its early moons

A computer simulation has indicated that the gas giant Jupiter was once a cannibal, in the sense that it ate many of its moons early in its history.
The four giant Galilean moons orbiting Jupiter are the last survivors of at least five generations of moons that once circled the planet.
All the other moons - and there could have been 20 or more - were devoured by the planet in the early days of the solar system.

The view through his telescope startled him. He did not see only one object, but rather, one large world, with four smaller objects nearby.
These four objects are the moons we now call Io, Europa, Ganymede and Callisto.

S/2003 J 17 is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 22,134 Mm in 672.752 days, at an inclination of 162 to the ecliptic (161 to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2379.
