The sun moves in an orbit about the center of the Milky Way Galaxy at a speed of 290 km/s with a radius of 3 x 1020 km. Assuming all of the stars in the galaxy are concentrated near the center, and each star has a mass equivalent to the mass of the sun (2 x 1030 kg) How many stars are in the galaxy?
