Question
List at least three major differences between Pluto and the terrestrial planets.
Solution
-
Size and Composition: The first major difference between Pluto and terrestrial planets (like Earth, Mars, Venus, and Mercury) is their size and composition. Pluto is much smaller and is made up mostly of rock and ice, while terrestrial planets are larger and primarily composed of rock and metal.
-
Atmosphere: The second difference is their atmospheres. Pluto has a thin, weak atmosphere that expands when it comes closer to the sun and collapses as it moves farther away. On the other hand, terrestrial planets have more substantial atmospheres with weather systems and climate variations.
-
Orbit and Rotation: The third difference is in their orbit and rotation. Pluto has a more elliptical and inclined orbit compared to the terrestrial planets. It also has a slower rotation period, taking about 6.4 Earth days to complete one rotation on its axis. In contrast, terrestrial planets have relatively circular orbits and faster rotation periods.
