Eponym Tyagaraja

Tyagaraja is a crater on Mercury. Its name was adopted by the International Astronomical Union in 1976. Tyagaraja is named for the Indian composer Tyagaraja. [1] The crater was first imaged by Mariner 10 in 1974. [2]

Tyagaraja is the third-largest crater of the Kuiperian system on Mercury, at 97 km diameter, after Bartók crater and Amaral crater. [3]

Hollows are present within Tyagaraja. Within the extensive hollows of Tyagaraja is a dark spot of low reflectance material (LRM), closely associated with the central peak complex. [4] Another prominent dark spot is located to the southwest of Tyagaraja, on the north rim of an unnamed crater.

The larger Phidias is to the north, and the crater Stevenson is to the east.

The Eminescu quadrangle (H-9) is one of fifteen quadrangles on Mercury. It runs from 216 to 288° longitude and from -25 to 25° latitude. Named after the Eminescu crater, it was mapped in detail for the first time after MESSENGER entered orbit around Mercury in 2011. It had not been mapped prior to that point because it was one of the six quadrangles that was not illuminated when Mariner 10 made its flybys in 1974 and 1975. These six quadrangles continued to be known by their albedo feature names, with this one known as the Solitudo Criophori quadrangle.

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

Vivaldi is a crater on Mercury. It was named by the IAU after Italian composer Antonio Vivaldi in 1976. It has a prominent and nearly continuous inner ring whose diameter measures about half that of the outer ring. It is one of 110 peak ring basins on Mercury. Unlike some of the lunar multiringed structures, no vestiges of additional rings are apparent around this crater. It is classified as c3 age.

<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.

<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">Scarlatti (crater)</span> Crater on Mercury

Scarlatti is a pit-floored crater on Mercury, which was discovered in 1974 by the Mariner 10 spacecraft. It has a prominent peak ring, and it is one of 110 peak ring basins on Mercury. The crater floor is covered by the smooth plains material. The crater displays an arcuate collapse feature along the northeastern peak ring. The size of the pit, which was first noticed in MESSENGER images obtained in January 2008, is 38 × 12 km. Such a feature may have resulted from collapse of a magma chamber underlying the central peak ring complex of the crater. The collapse feature is an analog of Earth's volcanic calderas. Scarlatti is thought to have the same age as the Caloris basin.
