Eponym Jean Sibelius

Sibelius is a crater on Mercury. [1] It has a diameter of 94 kilometres (58 miles). Its name was adopted by the International Astronomical Union (IAU) in 1985. Sibelius is named for the Finnish composer Jean Sibelius. [2]

Sibelius has a complex central peak that is offset from the center to the southwest. Within the central peak complex is a dark spot of low reflectance material (LRM), closely associated with hollows. [3]

To the south of Sibelius is the crater Vincente, and to the east are Delacroix and Shelley.

<span class="mw-page-title-main">Eminescu (crater)</span> Crater on Mercury

Eminescu is a peak ring crater on Mercury 125 kilometers (78 mi) in diameter. Since there are very few later craters superposed on it, Eminescu appears to be a young crater formed around one billion years ago. It has a transitional morphology between larger more complex impact basins like Raditladi and smaller simpler central peak craters.

<span class="mw-page-title-main">Xiao Zhao (crater)</span> Crater on Mercury

Xiao Zhao crater 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.

Sander is a crater on Mercury within Caloris Basin. It has dark walls and bright patches on its floor. Unlike the rays of Bashō crater, the bright areas are not believed to be immature, but they are inherently bright. It is named after the German photographer August Sander (1876–1964).

<span class="mw-page-title-main">Amaral (crater)</span> Crater on Mercury

Amaral is a crater on the planet Mercury. With its smooth floor, surrounding ejecta, and small secondary 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 bright blue color in striking contrast to the otherwise orange tones of surface material nearby. The different color of the central peak likely indicates rocks with different chemical composition from those on the neighboring surface.

<span class="mw-page-title-main">Raditladi (crater)</span> Crater on Mercury

Raditladi is a large impact crater on Mercury with a diameter of 263 km. Inside its peak ring there is a system of concentric extensional troughs (graben), which are rare surface features on Mercury. The floor of Raditladi is partially covered by relatively light smooth plains, which are thought to be a product of the effusive volcanism. The troughs may also have resulted from volcanic processes under the floor of Raditladi. The basin is relatively young, probably younger than one billion years, with only a few small impact craters on its floor and with well-preserved basin walls and peak-ring structure. It is one of 110 peak ring basins on Mercury.

<span class="mw-page-title-main">Nāwahī (crater)</span> Crater on Mercury

Nāwahī is a crater on Mercury. Nāwahī crater is located within the large Caloris basin, near the western rim. The unusual dark material creating a halo around Nāwahī makes this crater of special interest, as the dark material likely represents rocks with a different chemical and mineralogical composition than those of the neighboring surface. The crater is named after Hawaiian patriot and painter Joseph Nāwahī.
