The speed of light in a vacuum is exactly 299,792,458 m/s. This speed is sometimes used to provide a convenient yardstick for large astronomical distances. (a) A light-second is the distance light travels in one second. If the Moon is 3.84×108 m from the Earth (center to center), how many light-seconds away is it? (b) A light-minute is the distance light travels in one minute. If the Earth is 1.50×1011 m from the Sun, how many light-minutes away is it? (Your answer also represents the number of minutes it takes for light to reach the Earth from the Sun.) (c) A light-year is the distance light travels in one year. The Sun is 28,000 light-years from the center of the Milky Way galaxy. What is this distance in meters?

An astronomical unit (AU) is equal to the averagedistance from Earth to the Sun, about 92.9 × 106 mi. Aparsec (pc) is the distance at which a length of 1 AUwould subtend an angle of exactly 1 second of arc (Figure 1-8). Alight-year (ly) is the distance that light, travelingthrough a vacuum with a speed of 186000 mi/s, would cover in 1.0year. Express the Earth–Sun distance in (a)parsecs and (b) light-years.

A parsec is an astronomical unit of distance where 1 parsec = 3.26 light-years (1 light year equals the distance traveled by light in one year). If the speed of light is 186,000 mi/s, calculate the distance in meters of an object that travels 9.6 parsecs.
