Question

How many AU are between the Sun and Pluto?

Answer 1

39.5 AU.

Explanation:

One AU is the distance between the Earth and the Sun. Pluto is 39 times further from the Sun than Earth is. One AU measures at `1.496 times 10^8`km. When we divide the distance from the sun to Pluto, we get 39.5.

The average distance of Pluto from the sun is `5.91 times 10^9` km
`(5.91 times 10^9) / (1.496 times 10^8) = 39.5`

The average distance of Pluto from the sun is 39.5 AU.

Pluto's orbit is quite eccentric. It's distance from the Sun is 29.7 AU at perihelion and 49.7 AU at aphelion. The average distance is 39.5 AU.
