Discussion Overview

The discussion revolves around the various forces acting on an object in near-Earth orbit, including gravitational, electromagnetic, and atmospheric influences. Participants explore the relevance and significance of different forces, as well as the definitions and contexts of "near-Earth" objects.

Discussion Character

  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant lists several forces acting on an object in near-Earth orbit, including gravitational forces from Earth, the Sun, and other celestial bodies, as well as electromagnetic forces and solar wind.
  • Another participant suggests that asking questions would be more beneficial than posting lists, implying that the initial list may lack utility.
  • A different participant defends the validity of the list and expresses frustration at the suggestion that it is dubious.
  • A subsequent reply critiques the inclusion of certain celestial bodies, arguing that the relevance of forces from distant stars and black holes is overstated.
  • One participant points out redundancy in the list regarding electromagnetic forces and light, gamma, and X-rays, and discusses the varying significance of atmospheric effects based on the orbital altitude.
  • There is a call for clarification on what is meant by "near-Earth object," noting the differences between low Earth orbit (LEO) and geostationary orbit (GEO) in terms of atmospheric influence.

Areas of Agreement / Disagreement

Participants express differing views on the utility of the initial list and the relevance of certain forces, indicating that multiple competing perspectives remain without a clear consensus.

Contextual Notes

Participants highlight the need for clarity regarding definitions and the significance of various forces, suggesting that assumptions about the context of "near-Earth" may affect the discussion.

Here is a list of some of the forces on an object in the solar system in near-Earth orbit:

Gravitation - Earth, Sun, Moon, Planets and the Milky Way's Supermassive Black Hole

Electromagnetic - Earth, Sun, Moon, Planets and the Milky Way's Supermassive Black Hole

Solar Wind Plasma from the Sun - Variable due to Solar Flares and its 11-year cycle

Earth' s Atmosphere

Light, Gamma and X-rays - Sun, Stars, Supernovas and Galaxies



Please feel free to add or chop up my list.

I think it would be more useful for you to ask questions than to post lists of dubious utility.
 
Alright the Stars, Supernovas, Galaxies and Black Hole is going a little too far. I have a valid right to post my list. And it is not "dubious".
 
I think it would be more useful to ask questions. I have no idea what your point is.

"Light, Gamma and X-rays - Sun, Stars, Supernovas and Galaxies" is redundant with "Electromagnetic - Earth, Sun, Moon, Planets and the Milky Way's Supermassive Black Hole", and a supermassive black hole is about gravity, not EM, unless one is referring to the EM from matter surrounding the BH.

What does one mean by 'near-earth object'. LEO and GEO are near-earth distances, but the atmosphere is a more significant factor for LEO than GEO, and there's essentially no atmosphere at GEO, but rather the solar wind is more significant. Effects from other stars/galaxies are negligible, and more or less isotropic.

Other than a list of natural phenomena, it's not clear to us one's objective.
