Discussion Overview

The discussion centers on the nature of Pluto's elliptical orbit around the Sun, exploring the gravitational forces and orbital mechanics involved. Participants examine the characteristics of Pluto's orbit in comparison to other planets, including its resonance with Neptune.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant notes that while all planets orbit the Sun in elliptical paths, Pluto's orbit is more elliptical than those of other planets, suggesting a potential link to its classification as a dwarf planet.
  • Another participant mentions that Pluto's orbit is in a 3:2 mean motion resonance with Neptune, which may influence its orbital characteristics.
  • A participant challenges the initial premise by questioning the derivation of the claim that Pluto's orbit appears inconsistent with the spacetime curvature created by the Sun.
  • There is a statement asserting that Pluto is not classified as a planet, which introduces a point of contention regarding its status.

Areas of Agreement / Disagreement

Participants express differing views on Pluto's classification and the implications for its orbit. There is no consensus on the reasons behind the characteristics of Pluto's orbit, and the discussion remains unresolved.

Contextual Notes

Some assumptions about gravitational forces and orbital mechanics are not fully explored, and the discussion includes unresolved questions about the calculations related to the curvature of spacetime.

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?
