What is the most obvious difference between terrestrial and jovian planets?
After size, perhaps the most noticeable difference between the jovian and terrestrial planets involves moons and rings. The terrestrial planets are nearly isolated worlds, with only Earth (1 moon) and Mars (2 moons) orbited by any moons at all. In contrast, many moons and rings orbit each of the jovian planets.
What are the two main differences between the terrestrial and jovian planets?
