that by the time you were on Pluto that the sun would be just another start in the sky indistinguishable from any other. Pluto in its aphelion phase of orbit (farthest distance) 4,583,189,130 miles and it's perihelion phase of orbit (closest distance) 2,756,915,000 miles. That's a pretty long ways. I say the sun would be a dot, a really small dot!
