The Sun travels in a circular orbit at a velocity of 220 km/second at a distance of 8.5 kiloparsecs from the center of the Galaxy (note that these numbers are slightly different from those in your book). Calculate the number of years it takes the Sun to complete an orbit (i. e., the circumference of a circle with an 8.5 kiloparsec radius) around the center of the Galaxy. (There are 3.1 x 1013 kilometers/parsec and 3.2 x 107 seconds/year.)
