..and yes, I know.. pluto is no longer even a planet!
but - does time pass at the same rate as on earth? ...understanding too that yes, time is relative....

Time doesn't have anything to do with the length of the path an object takes on its revolution around the sun. Time is just a system of measurement which we living on Earth have found to be the easiest to keep by, but is still flawed. The flaw is the 'leap year' which occurs every fourth year. That extra day actually comes from all the 'time' that we count extra, on a daily basis. A real day is not 24 complete hours, but we consider it that. It is the time gap between our 24-hour day and a 'real day' that causes us to have an extra 24 hours left over every 1460 days (4 years).
As I said, 'time' is just something we invented to explain when something has happened or will happened. And by stating that, 'time' on Pluto would pass at the same rate as on Earth, but there would be many more days in a year (90,613.3055 days, according to Wikipedia).

For anyone not needing six digits of accuracy, yes, time passes at the same rate here on earth as on Pluto.
The caveat is because of difference of gravity - the Sun's. Pluto is considerably farther from the Sun's Gravity Well, and thus it would be slightly faster. This is a consequence of General Relativity, where mass warps space and time. Being deeper in a gravity well makes things appear slower, relative to an outside observer.
I'm not up to doing the math, but I'd guess the difference would be less that one part in a million, probably close to one part in a billion.

Agree with John T, but not so much with Vincent G (rare). Velocities are relative to each other, so an observer on Earth would think his stationary clock was running faster than the clock on speedy Pluto, if this was the only affect. The gravity well makes the difference.
Vincent: Like Pluto, Concorde was also flying further out from the main gravity well, which would speed up its clock compared to ground level. However, acceleration and deceleration during flight would slow its clock just as gravity does. Which effect won out? Was the final reading ahead or behind the ground clock?

No and yes the distance from the sun to the earth is different then the distance from the sun to Pluto, the orbit of earth is as you know 365 days per year, as for Pluto, it's More like 90,600 days a year, this is do to it's large orbital ring, and the fact that it takes light 179 times longer to reach Pluto then earth, so time is curved like space and light, so if you lived on Pluto and i lived on earth and i sent you a message it would be something like 8 hours before you got the message. I hope this helps , good luck.

No, the time does not pass at the same rate as on earth. This due to the difference of distance between sun and pluto.

William K (and John T) is the one with the right answer.
Of course, the time difference is going to be extremely small, but it would nonetheless be measurable.
Because of its relative proximity to the sun, the earth has to orbit at a speed of 30.287 km/sec; while Pluto average 4.666 km/sec.
According to Mr. Einstein, the faster you go, the slower time goes from the perspective of an observer. And that effect was actually demonstrated experimentally by having an atomic clock fly abroad the Concorde (at Mach 2.2, which is a mere 0.6027 km/sec) for a few hours, and it had drifted by a few nanoseconds when compared with an atomic clock that stayed on the ground.

Yes time passes at the same rate on Earth and Pluto. Pluto's days and years are different though.

no
Space-time near masive objects is warped the more masive they are so for an observer on earth, time will run slower than for an observer on pluto (granted that the difference won't be huge)

Yes, but the differences due to relativity are miniscule.

no all planets spin at a different rate just like they go around the sun at a different rate. i don't know what it is but deff no
