Cannibalistic Jupiter

Jupiter is the largest planet of our solar system. This planet that looks like a mighty sphere of air used to swallow its own moons in its earliest days. Scientists have discovered this fact through a computer model which shows that it has swallowed many such moons of itself.
Currently four Galilean moons are revolving around Jupiter and they are the only four that have survived. Scientists have predicted that earlier, there were 20 such moons revolving around jupiter, which nobody could have imagined and most of these moons got merged with it.
Robin Canup, a researcher from Southwest Research Institute in Boulder, Colorado has done has done a deeper study of this fact.
