| Eponym | Ernest Hemingway |
Hemingway is a crater on Mercury. It has a patch of very dark material located near its center. The dark color is likely due to rocks that have a different mineralogical composition from that of the surrounding surface.[1]
The crater's name was adopted by the International Astronomical Union (IAU) in 2009. It is named for the American author Ernest Hemingway.[2] [why? ]
The small crater Makeba is southeast of Hemingway.
Dark interior crater
[edit ]The dark impact crater near the center of Hemingway is truly black, and due to its superposition over the other structures in the crater, it is a young feature. The dark material is probably abundant in the subsurface of the crater and is being exposed by mass wasting processes and the formation of hollows.[3]
