Orbit of the planet Pluto

  1. Dec 22, 2009 #1
    I understand that planets orbit follows a curve in spacetime created by the sun. Most of the planets follow the curve with seemingly a consistent radius. However Pluto follows an ellipse around the sun an appears to be inconsistent with the curve in spacetime created by the sun. Apologies if this is far too a simplistic question, but what gravitational forces are in play that cause Pluto’s ellipse orbit?

    Thanks in advance,

    All planets orbit the Sun on elliptical orbits, Pluto's is just more elliptical than the others.

    Perhaps that is because it is a dwarf planet.

    It's orbit is also in a 3:2 mean motion resonance with Neptune's.

    Can you show us the calculations where you derive this?
