1.43807 x 10^17 meters
15.2 ly = 15.2 x 9.461 x 10^15 meters/light year
According to Wikipedia: http://en.wikipedia.org/wiki/Light_year
1 light year = 9.461×10^15 m
So the answer is 15.2 years x the meters per light year,
15.2 years x 9.461 X 10^15 meters/year = 1.43 X 10^17 years/years/meter = 1.43 x 10^17 meters.

1 light year ~ 1.e+16 m
15 light year~ 1.5e+17 m
===========================
Or
Distance = velocity x time
S = 3 x10^8 x 365.25x 24 x60x60 x15.52
S = 146932185600000000 m

it's simple..use i light yr=1yr..do the mathematical equation then.. else, use the plank's constant to attain the no. of meters...
