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 3.2*10^12 light-years from Earth. In scientific notation, approximately how many miles is it?

a) 1.88 * 10^12
b) 5.88 * 10^14
c) 3.2 * 10^15
d) 1.88 * 10^15

My answer is D, am I right?
