415 Palatia is a large main belt asteroid that was discovered by German astronomer Max Wolf on February 7, 1896 in Heidelberg.
10µ radiometric data collected from Kitt Peak in 1975 gave an overly large diameter estimate of 93 km. It has a very low radiometric albedo of 0.026 and the spectrum suggests a metal-rich enstatite composition.[2]
