light year :- The distance traveled by the light in one year is called a one light year.
1 ly = 3×10^8 × 60 × 60 × 24 × 365.25 m
1 ly = 946728 × 10^10 m
1 ly = 9.46728 × 10^15 m.
here , ly ----> light year
1 ly = 3×10^8 × 60 × 60 × 24 × 365.25 m

Answer:
order of magnitude of light year = 16
Explanation:
one light year is the distance travelled by light in one year.
speed of light, c = 3×10^8 m/s
t = 1 year = 365.25×24×60×60 s
1 light year = c×t
= 3×10^8×365.25×24×60×60 m
= 9.467×10^15 m
= 0.9467×10^16 m
HOPE THIS WILL HELP YOU☺
