Explanation Given data: We are located about 27 , 000 light-years from the galactic center. We orbit the center about once every 230 million years. Formula used: R o t a t i o n a l S p e e d = 2 π r T i m e T a k e n D i s t a n c e = S p e e d × T i m e t a k e n We are located about 27 , 000 light-years from the galactic center, so radius ( r ) is equal to 2.7 × 10 4 light-years. We orbit the center about once every 230 million years, so time taken is equal to 2.3 × 10 8 years. The distance that the light can travel is equal to the product of speed of light and time of travel. The speed of light is a constant equal to 299,792,458 m/s. A light-year is the distance the light can travel in 1 year. 1 l i g h t − y e a r = 299792458 m s × 1 km 1000 m × 60 s 1 min × 60 min 1 hr × 24 hr 1 day ×
