This formula uses 3 Variables
Variables Used
Eccentricity of Elliptical Orbit - Eccentricity of Elliptical Orbit is a measure of how stretched or elongated the orbit's shape is.
Distance Between Two Foci - (Measured in Meter) - Distance Between Two Foci is defined as the distance between the two focus, F1 and F2.
Semi Major Axis of Elliptic Orbit - (Measured in Meter) - Semi Major Axis of Elliptic Orbit is half of the major axis, which is the longest diameter of the ellipse describing the orbit.
STEP 1: Convert Input(s) to Base Unit
Distance Between Two Foci: 20400 Kilometer --> 20400000 Meter (Check conversion ​here)
Semi Major Axis of Elliptic Orbit: 16940 Kilometer --> 16940000 Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ee = dfoci/(2*ae) --> 20400000/(2*16940000)
Evaluating ... ...
ee = 0.602125147579693
STEP 3: Convert Result to Output's Unit
0.602125147579693 --> No Conversion Required
FINAL ANSWER
0.602125147579693 0.602125 <-- Eccentricity of Elliptical Orbit

What is Orbit ?

An orbit is the path followed by an object as it revolves around another object in space due to gravitational attraction. Orbits are fundamental to celestial mechanics and describe the motion of planets, moons, satellites, and other celestial bodies around larger bodies such as stars, planets, or black holes.
