The solar system is 25,000 light years from the center of our milky way galaxy. one light year is the distance light travels in one year at a speed of 3.0×108m/s. astronomers have determined that the solar system is orbiting the center of the galaxy at a speed of 230 km/s.
assuming the orbit is circular, what is the period of the solar system's orbit?
