1 light year = 5.9 * 10^12 miles

3 light years:

3 * 5.89 * 10^12 miles =

1.767 * 10^12 miles =

1.767 * 10^13 miles

How long does it take to get there?

(1.767 * 10^13) / (17000) =

(1.767 * 10^13) / (1.7 * 10^4) =

1.03941176471 * 10^9 =

1039411764.71 ≈ 1,040,000,000

It will take about 1,040,000,000 hours to get to a star that is 3 light years away.
