Xiao Zhaocrater is small in comparison with many other craters on Mercury. However, Xiao Zhao's long bright rays make it a readily visible feature. The fresh, bright rays, which were created by material ejected outward during the impact event that formed the crater, indicate that Xiao Zhao is a relatively young crater on Mercury's surface.[1]
Hollows are present within Xiao Zhao and on the ejecta blanket near the rim. A confirmed dark spot is present in Xiao Zhao.[2] This dark spot is associated with the hollows.
Xiao Zhao was named by the IAU in 2008 after the 12th-century Chinese painter Xiao Zhao.[3]
