Controls

The classic rubber-sheet picture of gravity: mass warps the grid, and a body orbits in the curved surface. Drag the star to move the mass and reshape the well; drag empty space to orbit the view.

Governing equation

Φ = - \frac{GM}{r} = - \frac{60 G}{r}, F = \frac{GM m}{r ^{2}}

Reading this result: At mass 60 the well is moderately curved; the body traces a near-stable ellipse because its sideways motion balances the inward pull (∝ M/r²).
