Renoir is a
peak ring basin, one of 110 on Mercury,[2] including
Raditladi and
Rachmaninoff. Though these basins are relatively young geologic features, Renoir is one of the oldest of its type. Because of its greater age, Renoir displays more of the effects of
tectonics and later impact events than the other peak ring impact basins.[3] It is thought to have formed at the end of the period with the highest meteor impact rates in Mercury's history. It is located in the
Kuiper quadrangle.[4] Renoir also has an area of high
reflectance, classified as a plain, resulting from previous volcanic activity on the planet.[5][6] Like Rachmaninoff, it is a basin with a high-reflectance plain located entirely within the central peak ring.[7]
Structure
Renoir has a concentric ring structure, meaning that it is also called a "concentric ring basin".[8] Its interior rim is distinct, however, similar basins usually have a more distinct outer rim than inner rim. Basins like Renoir are known for having deep valleys in and around them. Mercury's lower radius and mass compared to other bodies like
Mars mean that its basins - including Renoir and
Rodin - have a greater diameter; consequently, the multi-ring basins on bodies like the
Moon, including basins like
Hertzsprung and
Mare Orientale, are even larger than those on Mercury.[8]
