A star like the sun has serveral bodies moving around it at different distance. Consider that all of them are moving in circular orbits. Let r be the distance of the body from the centre of the star and let its linear velocity be upsilon , angular velocity omega , kinetic energy K , gravitational potential energy U , total energy E and angular momentum L .
