SUMMARY
The discussion centers on the YORP (Yarkovsky-O'Keefe-Radzievskii-Paddack) effect calculation for asteroids. David inquires about a simplified method for estimating the YORP effect based on average asteroid characteristics. He discovers 'Rubincam's approximation' by Dr. Alan Harris, which provides a formula: dw/dt ~ +/- 18/(a^2*D^2), where 'a' is the semi-major axis in astronomical units (AU) and 'D' is the diameter in kilometers. This formula yields the change in cycles per day per million years.
