The possible orbital period of Pluto was calculated prior to its discovery. Between 1906 and 1930, Percival Lowell, William Pickering, and Clyde Tombaugh conducted an extensive search for 'the ninth planet' that disrupted Neptune's orbit. After confirmation of photographs, they calculated Pluto's revolution period and found historical images of Pluto that had previously been overlooked.

No answer Pluto orbits the Sun Pluto does not orbit the Earth


Why does Pluto's moon charon orbit around the earth instead of Pluto?

It doesn't. Charon is much too far away to be influenced by Earth's gravity. Charon is gravitationally bound to Pluto, but technically does not orbit it. Because Charon is fairly massive compared to Pluto the two object orbit around their common center of mass, which lies outside of Pluto.

Does Pluto orbit the sun every 2.5 Earth years?

The real answer is that PLuto is not a planet and doenst real orbit around something so its not going to orbit the sun in about 25000000000 years. YOU have to know this.


How many earth days does it take for Pluto to orbit the sun?

What is the size comparison of Earth and Pluto?

If Pluto's orbit were on the same plane as Earth's orbit, if Earth were directly between the sun and Pluto, if Earth were at its aphelion (the point in its orbit where it's farthest from the sun), and if Pluto were at its perihelion (the point in its orbit closest to the sun), on the scale where the diameter of Earth is 5 mm, the distance from Earth to Pluto is about 1.681 km (a little over a mile).
