Caloris Planitia (also known as the Caloris Basin) is a plain within a large impact basin on Mercury, informally named Caloris, about 1,550 km (960 mi) in diameter. It is one of the largest impact basins in the Solar System. "Calor" is Latin for "heat" and the basin is so-named because the Sun is almost directly overhead every second time Mercury passes perihelion. The crater, discovered in 1974, is surrounded by the Caloris Montes, a ring of mountains approximately 2 km (1.2 mi) tall.

Deformational histories of the massive infill within Sputnik Planitia (Pluto) and Caloris Basin (Mercury) : Implications for BepiColombo data interpretation and the relationship between the parameters which induce tectonic subsidence. Throughout the Solar System, large infilled basins exhibit a variety of infilling processes, encompassing sedimentary mechanisms (i.e. aeolian or aqueous) and upwelling of material from beneath the basin floor (i.e. mantle pluming, cryovolcanism, mud volcanism, springs). This study compares two such basins, Sputnik Planitia (1000 km diameter) on Pluto and Caloris Basin (1500 km diameter) on Mercury, both believed to have been infilled through upwelling from th…

The Caloris group is a set of geologic units on Mercury. McCauley and others have proposed the name “Caloris Group” to include the mappable units created by the impact that formed the Caloris Basin and have formally named four formations within the group, which were first recognized and named informally by Trask and Guest based on imagery from the Mariner 10 spacecraft that flew by Mercury in 1974 and 1975. The extent of the formations within the group have been expanded and refined based on imagery and other data from the MESSENGER spacecraft which orbited Mercury from 2011 to 2015, and imaged parts of the planet that were in shadow at the time of the Mariner 10 encounters. Like the Imbriu…

Kerouac is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 2015, after American author and poet Jack Kerouac. Kerouac is located west of the Caloris Planitia, within Mearcair Planitia. To the west of Kerouac is the peak ring basin Raditladi.

Odin Planitia is a large basin on Mercury. It was named after the Norse god Odin, who was sometimes considered to be the equivalent of the Roman god Mercury, in 1976 by the IAU. It was first observed in detail by Mariner 10. The plain is approximately 473 kilometers in diameter. A large volcanic dome 7 km in diameter and 1.4 km high is situated near the center of Odin. Odin Planitia is located east of the Caloris basin. The southern portion is mapped on the Tolstoj quadrangle, and the northern portion is on the Shakespeare quadrangle. Odin Planitia is one of four named plains that surround the Caloris basin (with Mearcair Planitia, Stilbon Planitia, and Tir Planitia). All of these plains ar…
