General properties of closed curves on a sphere












0












$begingroup$


This is a question from a physicist trying to understand space curves.



In 2D, a closed curve equidistant from a point is a circle, and has constant curvature and zero torsion.



What can be said for a closed curve equidistant from a point in 3D, i.e. lying on the surface of a sphere? What are its properties?
