1. What is Eccentricity of Elliptical Orbit?

Eccentricity of Elliptical Orbit is a measure of how stretched or elongated the orbit's shape is. It quantifies the deviation of the orbit from a perfect circle.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( e_e \) — Eccentricity of Elliptical Orbit
• \( d_{\text{foci}} \) — Distance Between Two Foci (meters)
• \( a_e \) — Semi Major Axis of Elliptic Orbit (meters)

Explanation: The formula calculates the eccentricity by dividing the distance between the two foci by twice the semi-major axis of the elliptical orbit.

3. Importance of Eccentricity Calculation

Details: Calculating orbital eccentricity is crucial for understanding the shape and characteristics of elliptical orbits in celestial mechanics and orbital dynamics.

4. Using the Calculator

Tips: Enter the distance between two foci and the semi-major axis in meters. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of possible values for eccentricity?
A: Eccentricity values range from 0 (perfect circle) to 1 (parabolic orbit).

Q2: How does eccentricity affect orbital characteristics?
A: Higher eccentricity means more elongated orbits with varying orbital speeds and distances from the central body.

Q3: Can eccentricity be greater than 1?
A: For elliptical orbits, eccentricity is always between 0 and 1. Values greater than 1 indicate hyperbolic orbits.

Q4: What are some real-world applications of eccentricity calculation?
A: Used in astronomy, satellite orbit design, and space mission planning to determine orbital parameters.

Q5: How accurate is this calculation method?
A: The formula provides exact mathematical results for ideal elliptical orbits based on the input parameters.
