Asteroids predicted/corrected surface ages

The models were further validated by applying them to S-, Sq-, and Q-type asteroids, evaluating their ability to capture two key trends: the SW progression across chondritic S-type asteroids and the relationship between asteroid size and surface age. Both models successfully identify relatively fresh surfaces in Q-type asteroids and mature surfaces in S-type asteroids, as well as younger surface ages for asteroids with diameters less than 5 km.

However, the GP model exhibits higher variability in predictions for the asteroid dataset. While both models effectively capture relative surface age trends, limitations in data availability between 10^3^ and 10^7^ years hinder precise predictions of asteroid surface ages. These models have significant potential for future applications, such as determining the surface age for individual asteroids and identifying asteroid families, offering valuable tools for advancing our understanding of asteroid evolution and SW processes.
