Roche Limit Calculator

Enter the mass of the central object and the satellite density into the calculator to determine the Roche limit.

Roche Limit Formula

The following equation is used to calculate a Roche limit.

R = [ (100*M) / (9*pi*p) ] ^ 1/3

  • Where R is the Roch limit also know as the radius
  • M is the mass of the central object
  • p is the density of the satellite

FAQ

What is the Roche limit?

The Roche limit is the distance at which an orbiting object or satellite will form rings around a larger body. This is also known as the point at which an object will be captured.

How is the Roche limit calculated?

The limit depends only on the mass of the central object and the density of the satellite.
