The "s" in the geodesic equation refers to the "surface area" for that portion of the orbit around a star or black hole.(adsbygoogle = window.adsbygoogle || []).push({});

For a small enough "delta t" the surface areas are the same.

Around a small star the orbital surface area (without the other interfering gravitational sources) would look something like an sphere or an ellipsoid.

How would you describe what the surface area and the geodesic equation around the Sun?
