Eccentricity is a scientific term used to describe how much an orbit deviates from a perfect circular shape. It is commonly applied in astronomy to understand the movement of planets, satellites, and other celestial bodies.
Key Characteristics
- Value ranges between 0 and 1
- Determines orbital shape and distance variation
Types of Orbits
- Circular orbit (low eccentricity)
- Elliptical orbit (moderate eccentricity)
- Highly elongated orbit (high eccentricity)
Examples
- Earth’s nearly circular orbit
- Comets with highly eccentric orbits
- Seasonal variations caused by orbital changes
