Mercury is the first planet from the Sun and the smallest in the Solar System. ... Its largest crater, Caloris Planitia, has a diameter of 1,550 km ...
This list contains a selection of objects 50 and 99 km in radius (100 km to 199 km in average diameter). The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following ...
Caloris Planitia / k ə ˈ l ɔːr ɪ s p l ə ˈ n ɪ ʃ (i) ə / is a plain within a large impact basin on Mercury, informally named Caloris, about 1,550 km (960 mi) in diameter. [1] It is one of the largest impact basins in the Solar System.
Astronomy on Mercury is the sky as viewed from the planet Mercury. ... The Sun will have an angular diameter of 1.733 to 1.142°. From perihelion to aphelion, ...
Mercury's Caloris Basin is one of the largest impact features in the Solar System. Craters on Mercury range in diameter from small bowl-shaped craters to multi-ringed impact basins hundreds of kilometers across. They appear in all states of degradation, from relatively fresh rayed-craters, to highly degraded crater remnants.
Mercurian: 414 craters (7.9%) Lunar: 1,624 craters (31.1%) Martian: 1,092 craters (20.9%) Venusian: 900 craters (17.2%) Others: 1,198 craters (22.9%) Distribution of named craters in the Solar System as of 2017 [a] This is a list of named craters on Mercury, the innermost planet of the Solar System (for other features, see list of geological features on Mercury).

Currently that alignment occurs within a few days of May 8 (descending node) and November 10 (ascending node), with the angular diameter of Mercury being about 12″ for May transits, and 10″ for November transits. The average date for a transit increases over centuries as a result of Mercury's nodal precession and Earth's axial precession.
Rūmī is a crater on Mercury. It has a diameter of 75 kilometres (47 miles). It has a diameter of 75 kilometres (47 miles). Its name was adopted by the International Astronomical Union (IAU) in 1985.
