Sun orbits at roughly 26,000 ly from the center of the galaxy and takes 225 million years to make one orbit. i: at what speed does sun revolve around the center of the galaxy? (give your answer in km/s; show all work.) ii: what is the circumference of sun's orbit if we consider its orbit to be circular? iii: what is the mass of the galaxy within sun's orbit?

The sun orbits the milky way galaxy once each 2.60 x 108 y, with a roughly circular orbit averaging 3.00 x 104 light years in radius. (a light year is the distance traveled by light in 1 y.) calculate the centripetal acceleration of the sun in its galactic orbit.

(a) the sun orbits the milky way galaxy once each 2.60 x 108y , with a roughly circular orbit averaging 3.00 x 104 light years in radius. (a light year is the distance traveled by light in 1 y.) calculate the centripetal acceleration of the sun in its galactic orbit. does your result support the contention that a nearly inertial frame of reference can be located at the sun? (b) calculate the average speed of the sun in its galactic orbit. does the answer surprise you?
