Eccentric Anomaly in Elliptic Orbit given True Anomaly and Eccentricity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Eccentric Anomaly = 2*atan(sqrt((1-Eccentricity of Elliptical Orbit)/(1+Eccentricity of Elliptical Orbit))*tan(True Anomaly in Elliptical Orbit/2))
E = 2*atan(sqrt((1-e_e)/(1+e_e))*tan(θ_e/2))
This formula uses 3 Functions, 3 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
atan - Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle., atan(Number)
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Eccentric Anomaly - (Measured in Radian) - The Eccentric Anomaly is an angular parameter that defines the position of a body that is moving along an Kepler orbit.
Eccentricity of Elliptical Orbit - Eccentricity of Elliptical Orbit is a measure of how stretched or elongated the orbit's shape is.
True Anomaly in Elliptical Orbit - (Measured in Radian) - True Anomaly in Elliptical Orbit measures the angle between the object's current position and the perigee (the point of closest approach to the central body) when viewed from the focus of the orbit.

STEP 1: Convert Input(s) to Base Unit

Eccentricity of Elliptical Orbit: 0.6 --> No Conversion Required
True Anomaly in Elliptical Orbit: 135.11 Degree --> 2.3581143523691 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E = 2*atan(sqrt((1-e_e)/(1+e_e))*tan(θ_e/2)) --> 2*atan(sqrt((1-0.6)/(1+0.6))*tan(2.3581143523691/2))

Evaluating ... ...

E = 1.76059061221031

STEP 3: Convert Result to Output's Unit

1.76059061221031 Radian -->100.874411530023 Degree (Check conversion here)

FINAL ANSWER

100.874411530023 ≈ 100.8744 Degree <-- Eccentric Anomaly

(Calculation completed in 00.020 seconds)
