Length of Radius Vectors at Perigee Solution

STEP 0: Pre-Calculation Summary

Formula Used

Perigee Radius = Major Orbital Axis*(1-Eccentricity)
r_perigee = a_orbit*(1-e)
This formula uses 3 Variables

Variables Used

Perigee Radius - (Measured in Meter) - Perigee Radius refers to the distance between the center of the Earth and the point in a satellite's orbit that is closest to the Earth's surface.
Major Orbital Axis - (Measured in Meter) - Major Orbital Axis is the sum of perihelion and the aphelion of the orbit gives the value of the major axis as the sum defines the largest diameter.
Eccentricity - Eccentricity refers to a characteristic of the orbit followed by a satellite around its primary body, typically the Earth.

STEP 1: Convert Input(s) to Base Unit

Major Orbital Axis: 7900 Kilometer --> 7900000 Meter (Check conversion here)
Eccentricity: 0.12 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_perigee = a_orbit*(1-e) --> 7900000*(1-0.12)

Evaluating ... ...

r_perigee = 6952000

STEP 3: Convert Result to Output's Unit

6952000 Meter -->6952 Kilometer (Check conversion here)

FINAL ANSWER

6952 Kilometer <-- Perigee Radius

(Calculation completed in 00.004 seconds)
