Does the Reduced Mass Trace an Ellipse in a Rotating Two-Body System?

Click For Summary
SUMMARY

In a rotating two-body system, the reduced mass effectively traces an ellipse around the center of mass. This conclusion is based on the principles of orbital mechanics, where the reduced mass simplifies the analysis of the gravitational interaction between two bodies. The concept is crucial for understanding the dynamics of celestial bodies, particularly in systems like the Earth-Sun model.

In a system of two rotating masses about a point (i.e, the sun), would the reduced mass (used for calculations) trace out another ellipse?
