C) extensive satellite systems

Explanation: Jupiter, Saturn, Neptune and Uranus are called Jovian planet. They are mostly characterised by what they are made up of, which is mainly gases (Hydrogen and Helium). They have so solid surface and are much larger in size compared to the terrestrial planet (Earth, Mars, Venus, Mercury). Jovian planet are very far away from the sun and they have extensive satellite system i.e they have a combined 166 number of moons in their orbit. Because of their sizes, they easily capture wandering objects into their orbits permanently or semi-permanent.
