Question

$1$ parsec equals to:

• A. $3.26$ light years
• B. $3.1\times {10}^{13}km$
• C. $1.92\times {10}^{13}miles$
• D. all of the above

Answer 1

Answer: (D)

all of the above

$1$ parsec = $3.26$ light years

$=3.6\times 9.46\times {10}^{12}km$

$\approx 3.1\times {10}^{13}km$

$=\frac{3.1\times {10}^{13}}{1.6}miles$

$\approx 1.92\times {10}^{13}miles$
