Dark matter within the solar system

Click For Summary
SUMMARY

The discussion centers on the distribution of dark matter within the solar system, specifically regarding its presence within Neptune's orbit. Studies, including those referenced in arXiv paper gr-qc/0602095, have quantified the amount of dark matter in the solar system, suggesting it can be expressed in terms of Earth masses. However, participants note that dark matter is not uniformly distributed throughout the galaxy, indicating variability in its concentration.

PREREQUISITES
  • Understanding of dark matter and its role in astrophysics
  • Familiarity with gravitational theories and their implications
  • Knowledge of celestial mechanics, particularly regarding planetary orbits
  • Basic skills in interpreting scientific research papers
NEXT STEPS
  • Research the implications of dark matter distribution on planetary orbits
  • Explore the methodologies used in the study referenced (arXiv gr-qc/0602095)
  • Investigate alternative theories regarding dark matter homogeneity
  • Learn about the techniques used to calculate mass distributions in astrophysics
USEFUL FOR

Astronomers, astrophysicists, and students studying cosmology or gravitational physics will benefit from this discussion, particularly those interested in dark matter research and its effects on solar system dynamics.

If dark matter is evenly distributed throughout the galaxy then how much should be within the orbit of neptune?

Studies have already been done constraining the amount of dark matter within the solar system - e.g., http://arxiv.org/abs/gr-qc/0602095. You might find it interesting to calculate the total amount in terms of Earth masses.

Dark matter distribution, however, is not believed to be homogenous throughout the galaxy, to my knowledge. Provide a link if you know of a source claiming otherwise.
