The Outer Planets: Jupiter, Saturn, Uranus, and Neptune
Introduction:
The outer planets in our solar system are Jupiter, Saturn, Uranus, and Neptune. These four gas giants are the largest planets in our solar system and are located beyond the asteroid belt.
Key Concepts:
- Jupiter is the largest planet in our solar system and has the most massive and intense magnetic field.
- Saturn is known for its ring system made up of ice and rock particles.
- Uranus and Neptune are referred to as "ice giants" due to their composition of water, methane, and ammonia ices.
- All four planets have many moons, with Jupiter having the most, and Neptune having the fewest.
Equations and Formulas:
- None required for this lesson.
Examples:
- Jupiter’s Great Red Spot, a giant storm on the planet’s surface, is larger than the Earth.
- Saturn’s rings have gaps called Cassini divisions, named after the spacecraft that discovered them.
- Uranus and Neptune have unusual magnetic fields, tilted at an angle compared to the planets’ rotation axis.
