Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5.88 × 10^12 miles. Suppose a star is 9.8 × 10^3 light-years from Earth. In scientific notation, approximately how many miles is it? (1 point
- The distance in miles can be found by multiplying the distance in light-years by the distance light can travel in one year.
9.8 x 10^3 light-years * 5.88 x 10^12 miles = 5.76 x 10^16 miles
Therefore, the star is approximately 5.76 x 10^16 miles from Earth.
