How long does the light take to reach Pluto?

[Urge]

I have heard that it takes eight minutes from the sun to the earth, but how long does it take to Pluto, and what about Eris?

I have been looking for info on how far the different planets are from the sun in light-minutes, but have been unsucsessfull so far.

A light second is 186,000 miles.
Find the miles, do the math.

Hey, something Wolfram Alpha is good for:

You're not looking very hard then. Google this: "pluto light minutes from sun"

Wow. That's some serious eccentricity!

Remember also that all planetary orbits are not precisely equal, especially not Pluto's where part of its orbit bring itself closer to the sun than Neptune - its aphelion is 7,375,927,931km, perihelion 4,436,824,613km, its oft-quited semi-major axis lying at 5,906,376,272km.

Given that one light second is 299,792.458km, that makes Pluto between 14,799.65 light seconds (246.66 light minutes, or 4.11 light hours) and 24,603.44 light seconds (410 light minutes, or 6.8 light hours) away - based on its semi-major axis, 19,701.55 light seconds (328.36 light minutes, or 5.47 light hours).

Like I said, that's some serious eccentricity!
