## Radius of Sphere of Influence Solution

STEP 0: Pre-Calculation Summary
Formula Used
R2 = (R1/0.001)*(M1/M2)^(2/5)
This formula uses 3 Variables
Variables Used
Planet 1 radius - Planet 1 radius is the radius of the first considered planetary body. (Measured in Kilometer)
Planet 1 Mass - Planet 1 Mass is the mass of the first planetary body. (Measured in Kilogram)
Planet 2 Mass - Planet 2 Mass is the mass of the second planetary body. (Measured in Kilogram)
STEP 1: Convert Input(s) to Base Unit
Planet 1 radius: 14000000 Kilometer --> 14000000000 Meter (Check conversion here)
Planet 1 Mass: 5E+24 Kilogram --> 5E+24 Kilogram No Conversion Required
Planet 2 Mass: 1E+30 Kilogram --> 1E+30 Kilogram No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
R2 = (R1/0.001)*(M1/M2)^(2/5) --> (14000000000/0.001)*(5E+24/1E+30)^(2/5)
Evaluating ... ...
R2 = 106100159655.728
STEP 3: Convert Result to Output's Unit
106100159655.728 Meter -->106100159.655728 Kilometer (Check conversion here)
106100159.655728 Kilometer <-- Planet 2 radius

## What is Sphere of Influence(Black Hole)

The sphere of influence is a region around a supermassive black hole in which the gravitational potential of the black hole dominates the gravitational potential of the host galaxy

## How to Calculate Radius of Sphere of Influence?

Radius of Sphere of Influence calculator uses Planet 2 radius = (Planet 1 radius/0.001)*(Planet 1 Mass/Planet 2 Mass)^(2/5) to calculate the Planet 2 radius, Radius of Sphere of Influence in astrodynamics and astronomy is the oblate-spheroid-shaped region around a celestial body where the primary gravitational influence on an orbiting object is that body. Planet 2 radius is denoted by R2 symbol.

How to calculate Radius of Sphere of Influence using this online calculator? To use this online calculator for Radius of Sphere of Influence, enter Planet 1 radius (R1), Planet 1 Mass (M1) & Planet 2 Mass (M2) and hit the calculate button. Here is how the Radius of Sphere of Influence calculation can be explained with given input values -> 1.061E+8 = (14000000000/0.001)*(5E+24/1E+30)^(2/5).

### FAQ

What is Radius of Sphere of Influence?
Radius of Sphere of Influence in astrodynamics and astronomy is the oblate-spheroid-shaped region around a celestial body where the primary gravitational influence on an orbiting object is that body and is represented as R2 = (R1/0.001)*(M1/M2)^(2/5) or Planet 2 radius = (Planet 1 radius/0.001)*(Planet 1 Mass/Planet 2 Mass)^(2/5). Planet 1 radius is the radius of the first considered planetary body, Planet 1 Mass is the mass of the first planetary body & Planet 2 Mass is the mass of the second planetary body.
How to calculate Radius of Sphere of Influence?
