Question

The distance of planet Jupiter from the Sun is 5 AU. Express this distance in light
year and parsec.

Answer 1

Answer: Light year 1 light year ≈ 63 241 au x light year = 5 au x light year = 1 light year * 5 au / 63 241 au = 7.9 x 10-5 light year
Parsec 1 parsec ≈ 206 265 au x parsec = 5 au x parsec = 1 parsec * 5 au /206 265 au = 2.4 x 10-5 parsec
