The planets in Earth's solar system are composed of various forms of matter, primarily categorized into two groups: terrestrial (rocky) planets and gas giants.
1. **Terrestrial Planets** (Mercury, Venus, Earth, Mars):
- **Rocky Materials**: These planets are primarily composed of silicate rocks and metals.
- **Core Components**: They typically have a metallic core (iron and nickel) surrounded by a silicate mantle and crust.
- **Atmospheric Gases**: The atmospheres of these planets vary and may include gases such as carbon dioxide, nitrogen, oxygen, and others, depending on the planet.
2. **Gas Giants** (Jupiter, Saturn):
- **Hydrogen and Helium**: These planets are predominantly composed of hydrogen and helium gas.
- **Hydrogen Compounds**: They contain significant amounts of water, ammonia, and methane in their atmosphere.
- **Metallic Hydrogen**: In the very high-pressure interiors of these gas giants, hydrogen may exist in a metallic state.
3. **Ice Giants** (Uranus, Neptune):
- **Ices and Gases**: These planets are composed of heavier volatile substances, often referred to as “ices,” including water, ammonia, and methane, alongside hydrogen and helium.
- **Rocky Core**: Like gas giants, they also have a rocky core but are less massive and have a higher proportion of these ices in their composition.
Overall, the planets in the solar system contain a mix of rocky material, metals, ices, and gases depending on their classification and distance from the Sun.
