What Causes Pluto's Elliptical Orbit Around the Sun?

AI Thread Summary
Pluto's orbit around the Sun is indeed elliptical, which is characteristic of all planets, but its orbit is more eccentric compared to others. This eccentricity is partly due to its classification as a dwarf planet and its 3:2 mean motion resonance with Neptune. The gravitational interactions with Neptune influence Pluto's orbital path, contributing to its unique elliptical shape. Some participants in the discussion request calculations to better understand the gravitational forces at play. Overall, the conversation highlights the complexities of gravitational dynamics affecting Pluto's orbit.

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.

pluto is no a planet.

Can you show us the calculations where you derive this?

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
