Why is the Moon grouped with the terrestrial planets? Where does Pluto fit in?
” Terrestrial planets are smaller than jovian planets and have less mass but higher density. They are made up of rocks and metals. They have solid surfaces. They are closer to the Sun and closer together. Terrestrial planets are warmer, have few if any moons, and no rings. Jovian planets are larger than terrestrial planets and have more mass but lower density. They are made up of light gases and hydrogen compounds. They do not have solid surfaces and they are farther from the Sun and farther apart from each other. Jovian planets are cooler than terrestrial planets, have rings, and have many moons. The Moon is grouped with the terrestrial planets because it shares the same general characteristics of this group of planets. Pluto doesn’t fit in with either group because it is small and solid but also far from the Sun, cold, and made of low density ices. Pluto’s orbit is eccentric and significantly inclined. Some classify Pluto with comets, while others have proposed a new category of Plut
