Study Notes
Solar System Overview
- The Solar System includes the Sun and all objects orbiting it: planets, moons, asteroids, and comets.
- The Sun, a massive hot gas sphere, provides heat and light to all planets.
- Eight planets exist, categorized as inner rocky planets and outer gas giants.
Inner Rocky Planets
- Mercury: Smallest and closest to the Sun, experiencing extreme temperature variations
- Venus: Called Earth's twin, highly dense CO2 atmosphere, hottest planet
- Earth: Only known planet supporting life, 71% water-covered surface
- Mars: Red Planet, features Olympus Mons, the largest volcano in the Solar System.
Outer Gas Giants
- Jupiter: Largest planet, famous for the Great Red Spot — a long-lasting storm
- Saturn: Famous for its ring system, composed of ice and rock particles
- Uranus: Unique for rotating on its side
- Neptune: Farthest planet, holds the strongest winds within the Solar System.
Other Solar System Objects
- Asteroids: Primarily found in the asteroid belt between Mars and Jupiter
- Comets: Composed of ice and dust, with glowing tails when near the Sun
- Kuiper Belt and Oort Cloud: Regions containing icy bodies and dwarf planets like Pluto
Formation and Exploration
- The Solar System formed roughly 4.6 billion years ago from a gas and dust cloud.
- Scientists explore space using telescopes and spacecraft to understand planets, moons, and distant stars.
- Gravity keeps the planets in their orbits around the Sun.
