Roerich is a crater on Mercury, near the south pole. Its name was adopted by the International Astronomical Union in 2013, after the Russian painter Nicholas Roerich. [1]

Parts of Roerich crater are in permanent shadow. [2]

To the immediate south of Roerich is Lovecraft crater. Beyond it is Chao Meng-Fu crater, at the south pole.

<span class="mw-page-title-main">Mercury (planet)</span> First planet from the Sun

Mercury is the first planet from the Sun and the smallest in the Solar System. In English, it is named after the Roman god Mercurius (Mercury), god of commerce and communication, and the messenger of the gods. Mercury is classified as a terrestrial planet, with roughly the same surface gravity as Mars. The surface of Mercury is heavily cratered, as a result of countless impact events that have accumulated over billions of years. Its largest crater, Caloris Planitia, has a diameter of 1,550 km (960 mi) and one-third the diameter of the planet. Similarly to the Earth's Moon, Mercury's surface displays an expansive rupes system generated from thrust faults and bright ray systems formed by impact event remnants.

<span class="mw-page-title-main">Lander (spacecraft)</span> Type of spacecraft

A lander is a spacecraft that descends towards, then comes to rest on the surface of an astronomical body other than Earth. In contrast to an impact probe, which makes a hard landing that damages or destroys the probe upon reaching the surface, a lander makes a soft landing after which the probe remains functional.

<i>MESSENGER</i> Seventh mission of the Discovery program; orbital reconnaissance of the planet Mercury (2004–2015)

MESSENGER was a NASA robotic space probe that orbited the planet Mercury between 2011 and 2015, studying Mercury's chemical composition, geology, and magnetic field. The name is a backronym for "Mercury Surface, Space Environment, Geochemistry, and Ranging", and a reference to the messenger god Mercury from Roman mythology.

<span class="mw-page-title-main">Shackleton (crater)</span> Lunar impact crater

Shackleton is an impact crater that lies at the lunar south pole. The peaks along the crater's rim are exposed to almost continual sunlight, while the interior is perpetually in shadow. The low-temperature interior of this crater functions as a cold trap that may capture and freeze volatiles shed during comet impacts on the Moon. Measurements by the Lunar Prospector spacecraft showed higher than normal amounts of hydrogen within the crater, which may indicate the presence of water ice. The crater is named after Antarctic explorer Ernest Shackleton.

<span class="mw-page-title-main">Cabeus (crater)</span> Lunar impact crater

Cabeus is a lunar impact crater that is located about 100 km (62 mi) from the south pole of the Moon. At this location the crater is seen obliquely from Earth, and it is almost perpetually in deep shadow due to lack of sunlight. Hence, not much detail can be seen of this crater, even from orbit. Through a telescope, this crater appears near the southern limb of the Moon, to the west of the crater Malapert and to the south-southwest of Newton.

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

Chao Meng-Fu is a 167 km (104 mi) diameter crater on Mercury named after the Chinese painter and calligrapher Zhao Mengfu (1254–1322). Due to its location near Mercury's south pole and the planet's small axial tilt, an estimated 40% of the crater lies in permanent shadow. This combined with bright radar echoes from the location of the crater leads scientists to suspect that it may shelter large quantities of ice protected against sublimation into the near-vacuum by the constant −171 °C (−276 °F) temperatures.

<span class="mw-page-title-main">Geology of Mercury</span> Geologic structure and composition of planet Mercury

The geology of Mercury is the scientific study of the surface, crust, and interior of the planet Mercury. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology. In planetary science, the term geology is used in its broadest sense to mean the study of the solid parts of planets and moons. The term incorporates aspects of geophysics, geochemistry, mineralogy, geodesy, and cartography.

Ictinus is a crater on Mercury. Its depth from crater floor to rim is 4.8 km. Its name was adopted by the International Astronomical Union in 1976. Ictinus is named for the Ancient Greek architect Ictinus, who lived in the 5th century BCE.

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

Tolkien is one of the northernmost craters on Mercury, located in the Borealis quadrangle at 88.82 N, 211.08 W. It is 50 km in diameter. It was named after the South African born British writer J. R. R. Tolkien. The name was approved by IAU's Working Group for Planetary System Nomenclature on August 6, 2012. Since Tolkien is very close to the north pole, and Mercury has almost no axial tilt, Tolkien receives very little sunlight. S band radar data from the Arecibo Observatory collected between 1999 and 2005 indicates a radar-bright area covers the entire floor of Tolkien, which is probably indicative of a water ice deposit.

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

Magritte is a crater on Mercury, near the south pole. This crater was likely created by an impact event, as evident by its circular depression. Its name was adopted by the International Astronomical Union in 2012, after the Belgian painter, René Magritte. Magritte is one of several craters on Mercury named after famous artists. Per the Working Group for Planetary System Nomenclature, all Mercury craters are named after an artist who was famous for more than fifty years who has been deceased for more than three years at the time the crater is named.
