Abstract: Based on the geodesic equation in a static spherically symmetric metric wediscuss the rotation curve and gravitational lensing. The rotation curvedetermines one function in the metric without assuming Einstein-s equations.Then lensing is considered in the weak field approximation of generalrelativity. From the null geodesics we derive the lensing equation andcorrections to it.
