Palatia (minor planet designation: 415 Palatia) is a large main belt asteroid that was discovered by German astronomer Max Wolf on 7 February 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]
