Categorization of Planets in the Solar System

Hard Reading Comprehension Factual Information

The Solar System consists of the Sun and all celestial bodies that are bound to it by gravity. The eight planets orbit the Sun in elliptical paths and are categorized into two main groups: terrestrial planets and gas giants. The terrestrial planets, consisting of Mercury, Venus, Earth, and Mars, are characterized by their solid surfaces and relatively higher densities. In contrast, the gas giants—Jupiter, Saturn, Uranus, and Neptune—are noted for their thick atmospheres and lack of a defined solid surface. Each planet possesses unique features; for example, Jupiter is the largest planet, while Mars is known for its reddish appearance due to iron oxide. Additionally, the Solar System contains dwarf planets such as Pluto, along with numerous moons, asteroids, and comets, which contribute to its dynamic environment.
