Question

How many light years are there from Earth to Pluto?

Answer 1

Currently about `0.0005` ly

Explanation:

The distance between the Earth and Pluto varies between about `28.6` A.U. and `50` A.U. It is currently at about `33.8` A.U.

`1` A.U. is the average distance between the Sun and the Earth, which is about `8.3` light minutes.

So Pluto is approximately `33.8 * 8.3 ~~ 280` light minutes away.

There are `1440` minutes in a day and about `365` days per year, so in light years, the current distance to Pluto is about:

`280 / (1440 * 365) ~~ 0.0005` ly
