Our solar system is located about 27,000 light- years from the galactic center. How far does our solar system travel in one orbit?
A)1018 km
B)5)4 × 1017 km
C)1)7 × 1018 km
D)8)5 × 1017 km

The diameter of the Milky Way galaxy is estimated to be around 100,000 light-years, so the distance traveled by our solar system in one orbit would be approximately half of that, which is 50,000 light-years. Therefore, the distance in kilometers would be 50,000 x (9.46 x 10^12) km/light-year = 4.73 x 10^17 km, which is closest to option C: 1.7 x 10^18 km.
