Question

How is the distance 3.26 light years derived for a parsec?

Answer 1

Ans _ 3.084 into 1016 meter

Answer 2

$1parsec = \frac{1.496 \times {10}^{11}m }{ (\frac{1}{3600}) \times \ (\frac{\pi}{180}) } = 3.08 \times {10}^{16} m$

$= \frac{3.08 \times {10}^{16} }{9.46 \times {10}^{15} } ly$

$= 3.26ly$

1 light year = speed of light * time 1 year

$3 \times {10}^{8} {ms}^{ - 1} \times (365 \times 24 \times 60 \times 60s)$

$= 9.46 \times {10}^{15} m \\ = 9.4 \times {10}^{12} km$
