SUMMARY

This discussion focuses on determining orbital elements of asteroids using observational data. The user, equipped with an 8"-dobsonian mounted telescope, seeks guidance on calculating an asteroid's orbit from its observed motion. Key resources mentioned include the NASA Near Earth Object website and D. McNally's book "Positional Astronomy," which provides foundational knowledge for this mathematical exercise. The conversation emphasizes the importance of accurate positional data to derive heliocentric and geocentric coordinates.

PREREQUISITES
  • Understanding of orbital mechanics and celestial navigation
  • Familiarity with heliocentric and geocentric coordinate systems
  • Basic observational techniques using telescopes
  • Mathematical skills for calculating orbital elements
NEXT STEPS
  • Research methods for calculating orbital elements from positional observations
  • Explore the NASA Near Earth Object website for asteroid tracking resources
  • Study D. McNally's "Positional Astronomy" for foundational concepts
  • Learn about software tools for simulating asteroid orbits and tracking
USEFUL FOR

Astronomy enthusiasts, amateur astronomers, and students interested in asteroid observation and orbital mechanics will benefit from this discussion.

Hi everyone,
My latest acquisition is an 8"-dobsonian mounted telescope, and I thought I'd try a bit of asteroid observing. What I would like to do is record the asteroid's position over the course of several observations and as a mathematical exercise, calculate its orbit. I know how to use to a set of orbital elements to calculate an object's position, both heliocentric and geocentric in terms of RA and dec., however I'm having trouble finding resources on how to determine the orbital elements in the first place using observations showing the asteroid's motion. Can anyone point me in the right direction?

See this article on asteroid 1 Ceres:-

http://www.selsyn.co.uk/pkent/p/3c31p2.html

There is a series of references at the foot of that page, of which D. McNally's book Positional Astronomy is one I read ages back, and I would recommend as a good guide.
