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

Nov 30, 2015

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
