Rocky Planets (Terrestrial Planets)
* Mercury: The smallest planet and closest to the sun. It's a rocky, cratered world with a thin atmosphere.
* Venus: Often called Earth's "twin" due to its size, but its surface is incredibly hot and covered in thick clouds of sulfuric acid.
* Earth: Our home, with a diverse surface of oceans, continents, and an atmosphere that supports life.
* Mars: The "Red Planet," known for its rusty color and thin atmosphere. Evidence suggests it may have once had liquid water on its surface.
Gas Giants
* Jupiter: The largest planet in our solar system, composed primarily of hydrogen and helium. It has a swirling, colorful atmosphere and a faint ring system.
* Saturn: Famous for its stunning ring system, Saturn is also a gas giant composed mostly of hydrogen and helium.
* Uranus: An ice giant with a tilted axis, making it appear to rotate on its side. It has a faint ring system and is mostly composed of hydrogen, helium, and methane.
* Neptune: The farthest planet from the sun, Neptune is another ice giant with a blue appearance due to methane in its atmosphere. It has powerful winds and a faint ring system.
Key Differences
* Composition: Rocky planets are mainly composed of rock and metal. Gas giants are mostly composed of gases like hydrogen and helium.
* Density: Rocky planets are denser than gas giants.
* Structure: Rocky planets have solid surfaces, while gas giants don't have a clear surface. Their atmospheres gradually thicken as you go deeper.
