Question
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 $186,000 \mathrm{mi} / \mathrm{s}$, calculate the distance in meters of an object that travels $9.6$ parsecs.
Step 1
We know that 1 parsec = 3.26 light years, so: 9.6 parsecs * 3.26 light years/parsec = 31.296 light years Now, we need to convert light years to the distance traveled by light in meters. We know that the speed of light is 186,000 mi/s, and there are 31,557,600 Show more…

A parsec is an astronomical unit of distance where 1 parsec $=$ 3.26 light years $(1 \text { light year equals the distance traveled by }$ light in one year). If the speed of light is $186,000 \mathrm{mi} / \mathrm{s}$ , calcu-late the distance in meters of an object that travels 9.6 parsecs.
One parsec is about 3.26 light-years and 1 light-year is about $5.88 \times 10^{12} \mathrm{mi}$. Find the number of miles in 1 parsec.
