Good point. However, I also make distinction between gravitational mass and inertial mass. The sun would still have plenty of inertial mass, and it is this inertial mass that attracts (accelerates) the planets. You might ask, isn't the function of gravitational mass to attract? This answer is no. Gravitational mass reflects a body's indifference to having its gravitational acceleration impeded by another body. Harry
