A planet in our solar system is like the earth it is stable to live on but anything can happen while you are on it but and a dwarf planet it is not for everyday life so humans can not live on a dwarf planet like they could on one in the solar system
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)
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.
If water did not expand when freezing, then it would be denser than liquid water when it froze; therefore it would sink and fill lakes or the ocean from bottom to top. Once the oceans filled with ice, life there would not be possible.
