Most likely is a satellite path that crossed directly between Jupiter and the camera lens. As the satellite is much closer, it looks to be about the same size as Jupiter. However, it is interesting that it does appear to pass behind Jupiter. Of course if it is assumed that the object is closer, then its apparent light speed violation is only apparent, because of course it can occlude Jupiter very rapidly. The flaw in this hypothesis is the object is not round, but elongated.
Not likely to be a flying insect because it moves in a perfectly straight line.
Speculation - a ship using the Alcubierre Drive (which can theoretically exist but no one on Earth has any idea how to create such a drive - although NASA is supporting research on it) might display these characteristics. There is a lot of speculation regarding just how such a drive would appear from the "outside" e.g. what would an external viewer see. One idea is that any object inside the warp field would appear "stretched" to the length of the warped space. So a reasonably sized ship could appear to be as long as the diameter of Jupiter if the warp field was that long. If this is true, then such a vehicle could move that fast without violating the light speed limit, because inside the warp the ship would not even be moving at all.
