Recommendations for books on celestial mechanics include "Fundamentals of Astrodynamics and Applications" by Vallado, which is comprehensive but mathematically challenging. Another suggested title is "Fundamentals of Astrodynamics" by Bate, Mueller, and White, known for its affordability and continuous reprints. "Introduction to Space Dynamics" by William Tyrrell Thomson is also recommended for its insights into jet stabilization and gravity turns. The discussion highlights a distinction between celestial mechanics, focused on planetary movements, and astrodynamics, which deals with spacecraft navigation and control. Overall, various resources are available, including older texts and general physics books that cover celestial mechanics topics.
