Joshua say: The average distance Pluto is from the sun is 5,900,000,000 kilometers away. Pluto orbits the Sun once every 248 years. Basically, it takes several generations to make one complete orbit. Since there's no actual "starting point," you can say Pluto just completed an orbit at any time. 248 years ago from now, Pluto was in a similar place as it is now. You could say the same thing tomorrow, the next day, or 20 years from now. The point is, Pluto is very far away. If you look up hubble pictures of Pluto, you'll see (because of the small size of the dwarf planet) that hubbles pictures of galaxies are actually far better and more detailed. Of course, a galaxy spreads over thousands of light years while the diameter of Pluto is measured in miles or kilometers.

CarolOklaNola say: Pluto was at perihelion between 1979 and 199, but Pluto was discovered in 1930 and Pluto has a almost 248 Earth year orbit., .Pluto is still a LONG way from completing one orbit.
You don't state what time or year Pluto's orbit STARTED,so NO ONE can answer your question because of insufficient data and information ..
You claim to be an engineer. An engineer should know that they need to give specific information in their questions IF they want a factually correct answer.. You could have done your OWN research and looked this up yourself and answered your own question.

mike1942-f say: Just a few minutes ago. The orbit that started a couple of hundred years ago (248) ended a few minutes ago. What can your question possibly mean - that there is a starting point inscribed n the solar system?

Gary B say: it is ALWASY competeling an orbit.
WHERE did the oprbit start?

Ricki say: 1981, March 3rd. 8:21 PST am if you want to be precise.
