Answer
3.266 light year
Explanation:
that in 1 light year there is [tex]9.461\times 10^{13}[/tex] km
hence [tex]9.461\It is given that [tex]1\ pc=3.09\times 10^{13}[/tex] km
We knowtimes 10^{12}[/tex] km is equal to 1 light year
1 km equal to [tex]\frac{1}{9.461\times 10^{12}}[/tex] light year
So 1 pc that is equal to [tex]3.09\times 10^{13}[/tex] km = [tex]\frac{1}{9.461\times 10^{12}}\times 3.09\times 10^{13}=3.266[/tex] light year
