Amaral is acrater on theplanetMercury. With its smooth floor, surroundingejecta, and smallsecondary craters, it appears noticeably younger than the heavily cratered surface around it. Along with a smooth crater floor, Amaral also has a central peak. Bright material on this peak is of particular interest as it appears to have an unusual color. In color-enhanced images, the central peak of Amaral appears as a brightblue color in striking contrast to the otherwiseorange tones of surface material nearby. The different color of the central peak likely indicates rocks with differentchemical composition from those on the neighboring surface.[1]
Amaral is the second-largest crater of theKuiperian system on Mercury, at 105 km (65 mi) diameter, afterBartók at 118 km (73 mi). It is followed byTyagaraja crater.[2]
A confirmeddark spot is present in southeastern Amaral.[3]
