Question

Demonstrate that 1 pc equals 3.09 × 1013 km and that it also equals 3.26 light-years. Show your calculations.

Answer 1

Answer

3.266 light year

Explanation:

that in 1 light year there is $9.461\times 10^{13}$ km

hence $9.461\It is given that [tex]1\ pc=3.09\times 10^{13}$ km

We knowtimes 10^{12}[/tex] km is equal to 1 light year

1 km equal to $\frac{1}{9.461\times 10^{12}}$ light year

So 1 pc that is equal to $3.09\times 10^{13}$ km = $\frac{1}{9.461\times 10^{12}}\times 3.09\times 10^{13}=3.266$ light year
