Answer:
X: has moons and rings, the second most massive object in our solar system. (Saturn)
Y: not considered a gas giant, Unable to clear small-sized objects from its orbital path. (Pluto)
Step-by-step explanation:
There are 8 planets in the solar system. Four are terrestrial planets and four Jovian planets. Jovian planets are gas giants, have rings and many moons. Terrestrial planets are small and have less number of moons. The second most massive object is the gas giant planet Saturn. It has rings and many moons.
Dwarf planets are not considered as a gas giant. There are other similar sized objects in their orbital path. One of the dwarf planet is Pluto. It lies beyond the orbit of Neptune in Kuiper Belt.
