The eight planets of the solar system can be compared by grouping them into two main categories: the four inner, rocky terrestrial planets (Mercury, Venus, Earth, and Mars) and the four outer, gaseous Jovian planets (Jupiter, Saturn, Uranus, and Neptune). The inner planets are smaller, denser, and closer to the sun, with solid surfaces and few moons, while the outer planets are much larger, less dense, and farther from the sun, featuring thick atmospheres and numerous moons and rings. Inner planets (Terrestrial) Composition: Solid, rocky surfaces made of iron, nickel, and silicates. Size and mass: Smaller and less massive. Atmosphere: Thinner, often composed of carbon dioxide, nitrogen, and oxygen. Temperature: Generally warmer. Moons and rings: Have very few or no moons. Examples: Mercury, Venus, Earth, Mars. Outer planets (Jovian) Composition: Gaseous and icy, made mostly of hydrogen and helium, with no solid surface. Size and mass: Larger and more massive. Atmosphere: Thick atmospheres. Temperature: Colder. Moons and rings: Have many moons and prominent ring systems. Examples: Jupiter, Saturn, Uranus, Neptune.
