47. Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8.0×1011 solar masses. A star orbiting on the galaxy's periphery is about 6.0×104 light years from its center. (a) What should the orbital period of that star be? (Answer in Millions of Earth Years) Use 1.99×1030 kg for the Mass of the Sun. Question 7 0/1 pts 47. Astronomical observations of our Milky Way galaxy indicate that it has a mass of about 8.0×1011 solar masses. A star orbiting on the galaxy's periphery is about 6.0×104 light years from its center. (b) If its period is 6.0×107 years instead, what is the mass of the galaxy? (Answer in Trillions of Solar Masses) Use 1.99×1030 kg for the Mass of the Sun.
