## Abstract The total kinetic energy of the Galaxy is estimated from the potential energy by applying the virial theorem. The limits of the potential energy depend strongly on the value of the local escape velocity. They are estimated to be between โ7. 10^16^ __M__~ศฎ~ km^2^s^โ2^ and โ1. 10^16^ __M_
