Discussion Overview

The discussion explores the hypothetical scenario of harvesting materials from the solar system and the potential effects on Earth's orbit around the Sun. It considers theoretical implications related to mass changes, gravitational effects, and climate impacts, without reaching any conclusions.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants suggest that increasing the mass of the Earth could theoretically affect its orbit, particularly if the mass increase were significant.
  • Others argue that as long as the mass of the Earth remains relatively constant, there would be no adverse effects on its orbital dynamics.
  • One participant posits that adding mass unevenly could alter the tilt axis of the Earth, potentially impacting climate.
  • There is a discussion about the relationship between mass, gravity, and inertia, with some participants questioning how these factors would interact in the context of increased mass.
  • Another viewpoint mentions that a significant increase in Earth's mass could change the center of gravity of the solar system, but this would likely require a substantial amount of added mass.

Areas of Agreement / Disagreement

Participants express differing views on the implications of increasing Earth's mass, with some asserting it would have no effect on orbit, while others raise concerns about gravitational and climatic consequences. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Limitations include assumptions about future technology for material harvesting, the scale of mass addition, and the uniformity of mass distribution on Earth.

I'm wondering if the world ever reached a point where we harvested materials from the solar system and put them to use on Earth, would we ever have to worry about putting too much material on the Earth and somehow causing adverse affects to the orbit of the Earth around the sun?

I know this is a far-fetched question, but I'm just curious.



Feel free to move this thread to somewhere more appropriate if need be.

I guess if you started increasing the mass by too much, the Earth's current orbit velocity wouldn't be enough to keep it from moving closer to the Sun.

Seeing as you're talking about harvesting the material for use, if we could do that I guess you could also just replace material we don't need to keep the mass fairly constant. If you had the technology to bring it here, you'd probably have the technology to send it back as well. (;

This is of course entirely theoretical, I don't have a clue about future technology.

In short, as long as we kept the mass of the Earth fairly constant I'd assume it wouldn't have any adverse effect on the orbit.
 
The change in the mass of the Earth would have no effect on its orbit (unless it became a significant fraction of the mass of the sun - not too likely).
 
Would gravity not have more of an effect on a more massive object with the same velocity as a smaller object?

Yes, but the more massive object would also have more inertia
 
If the large mass wasn't added uniformly to the Earth, I envision it will change the tilt axis which would affect the climate.

Maybe it would change so much that we would roll around our orbit like Uranus!

Consider the difference between two objects orbiting the sun next to each other and the same two objects combined into one...
 
Well if you increased the mass of Earth, then the center of gravity of the solar system might change, altering the orbit, but it would probably have to be A LOT of mass.
