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
