Discussion Overview

The discussion centers around the calculation of celestial coordinates, exploring methods, resources, and the evolution of related texts. Participants express interest in both theoretical and practical aspects of celestial mechanics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that knowledge of spherical trigonometry is necessary for calculating celestial coordinates and inquires about different methods that could be employed.
  • Another participant provides links to introductory and advanced textbooks on the subject, indicating a range of resources available for further study.
  • A participant mentions that Smart's Spherical Astronomy is a highly regarded textbook but notes it is not application-oriented, suggesting a need for more practical guides.
  • There is a reference to Jan Meeus as a significant figure in the development of practical astronomical calculations, with specific titles of his works mentioned.
  • A later reply questions what has changed in Spherical Astronomy since the 1700s, to which another participant responds that the introduction of vectors represents a significant development.

Areas of Agreement / Disagreement

Participants express varying opinions on the resources available for learning about celestial coordinates and the evolution of the field, indicating a lack of consensus on the best approaches or texts.

Contextual Notes

Some participants reference specific texts and authors without providing detailed comparisons or evaluations of their content, leaving the discussion open to interpretation based on individual preferences and experiences.

I tried to find information on how to calculate celestial coordinates. Unfortunately, most of the information I was able to find described this topic from a conceptual standpoint.

I am assuming that this requires knowledge of spherical trigonometry, correct? Are there different methods one could employ to accomplish this task?

If you have done research in celestial mechanics, or could give advice on this topic, I would appreciate it.

Wow. Smart's Spherical Astronomy is still top drawer - textbook wise? I have a copy of that from the 70's, I think. It is a very good book. But not application oriented.

Howto guides started IMO with Jan (or Jean) Meeus. Google for 'jan meeus'

Astronomical Formulae for Calculators (1988), 4th ed Enlarged and revised, Willmann-Bell Inc, ISBN 0-943396-22-0

Astronomical Algorithms (1998), 2nd ed, ISBN 0-943396-61-1

He also has a series of books 'Mathematical Astronomy Morsels'

A lot of canned opensource programs arose from Meeus work:
http://astrolabe.sourceforge.net/ Astrolabe uses python (PC or Linux). This will calculate coordinates for objects.

What's changed in Spherical Astronomy since the 1700s ?

Thanks for the links I didn't have any to hand.
