Question

If Pluto is 5.5 light hours from the sun, how far is Pluto from the sun in AU?

Answer 1

Distance to Pluto in AU = 39.42 AU

Explanation:

5.5 Light hours = 0.000627424 Light years

1 Light Year = 9.4 x `10^12` km

0.000627424 Light Years = 0.000627424 * 9.4 x `10^12`

0.000627424 Light Years = 5.89 x `10^9` km

1 AU = 1.496 x `10^8` km

5.89 x `10^9` / 1.496 x `10^8`

Distance to Pluto in AU = 39.42 AU
