What is the distance in kilometres, if a star is at a distance of 10 parsec?

1 parsec = 3.26 light years

Thus, the galaxy is at a distance of

10 parsec = 10 × 3.26 light years

                = 32.6 light years

 

Now, 

1 light year = 9.46×10¹² km

Thus, the galaxy is at a distance of

32.6 light years = 32.6 × 9.46×10¹² km

                      = 308.4 × 10¹² km
