Amru Al-Qays is a crater on Mercury. The crater was first imaged by Mariner 10 in 1974. Its name was adopted by the IAU in 1976, after the pre-Islamic Arab poet Imru' al-Qais in honor of his impact on astronomy and the world. [1]
Amru Al-Qays is west of Nureyev crater, and both are located southeast of the Caloris basin in northern Tir Planitia.
Airy-0 is a crater inside the larger Airy Crater on Mars, whose location defined the position of the prime meridian of that planet. It is about 0.5 km (0.3 mile) across and lies within the dark region Sinus Meridiani, one of the early albedo features to be identified on Mars. In 2018, the IAU Working Group on Cartographic Coordinates and Rotational Elements recommended setting the longitude of the Viking 1 lander as the reference line. This definition maintains the position of the center of Airy-0 at 0° longitude, within the tolerance of current cartographic uncertainties.
Stickney is the largest crater on Phobos, which is a satellite of Mars. It is 9 km (5.6 mi) in diameter, taking up a substantial proportion of the moon's surface.
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.
As-Samaw’al bin ‘Ādiyā’ was an Arabian poet and warrior, esteemed by the Arabs for his loyalty, which was commemorated by an Arabic idiom: "awfá min as-Samaw’al".
The Memnonia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Memnonia quadrangle is also referred to as MC-16.
Lermontov is an impact crater on the planet Mercury. The crater is named after Mikhail Yuryevich Lermontov, a 19th-century Russian poet. The name was approved by the International Astronomical Union in 1976.
Tir Planitia is a large plain on the planet Mercury. The name Tir (تیر) is the Persian word for "Mercury",, and the name was approved in 1976. It was first observed in detail by Mariner 10. It lies between the large crater Mozart and the ancient Tolstoj basin.
Tolstoj is a large, ancient impact crater on Mercury. It was named after Leo Tolstoy by the IAU in 1976. The albedo feature Solitudo Maiae appears to be associated with this crater.
Hun Kal is a small crater on Mercury that serves as the reference point for the planet's system of longitude. The longitude of Hun Kal's center is defined as being 20° W, thus establishing the planet's prime meridian. The name "Hun Kal" means '20' in the language of the Maya.
Bashō is a crater on Mercury named after Matsuo Bashō, a 17th-century Japanese writer. Bashō crater is only 74.62 kilometers (46.37 mi) in diameter, but is a prominent feature on Mercury's surface, due to its bright rays. Photographs from NASA's Mariner 10 and MESSENGER spacecraft show a curious halo of dark material around the crater.
Verdi is an impact crater on the planet Mercury. It was named after Italian Romantic composer Giuseppe Verdi (1813–1901) in 1979, as recognized by the International Astronomical Union. The crater's extensive ejecta blanket and secondary crater field are superposed on plains materials and older craters.
Gibran is a crater on Mercury and is in the east of the Shakespeare quadrangle. It was named after Lebanese-American poet Khalil Gibran in 2009. Gibran is located east of the rayed crater of Degas and nearby Damer.
Dominici is a crater on Mercury. Dominici's bright rays indicate that it is relatively young, and the young rays appear light blue in enhanced-color images. Dominici also has bright material on its floor and is surrounded by crater ejecta and material that appears orange in enhanced color. These color differences, as in nearby Titian crater, suggest that the impact crater excavated material from beneath Mercury's surface that differs in composition from the surrounding surface. Dominici lies within a much larger impact structure, the Homer basin.
Al-Hamadhani is a crater on Mercury. It has a diameter of 186 kilometers. Its name was adopted by the International Astronomical Union in 1979. Al-Hamadhani is named for the Iranian writer Badi' al-Zaman al-Hamadani, who died in 1007 C.E.
Keats is a crater on Mercury. The crater's name was adopted by the International Astronomical Union (IAU) in 1976 and named after an English poet. This poet is known as John Keats, who lived from 1795 to 1821.
Mansur is a crater on Mercury. Its name was adopted by the International Astronomical Union in 1979. Mansur is named for the Indian artist Ustad Mansur, who lived in the 17th century CE.
Inter-crater plains on Mercury are a land-form consisting of plains between craters on Mercury.
Hipparchus is an impact crater in the Phaethontis quadrangle of Mars, located at 44.8° S latitude and 151.4° W longitude. It is 93 kilometers in diameter. It was named after the ancient Greek astronomer Hipparchus in 1973.
Nureyev is a crater on Mercury. It has a diameter of 16 kilometers, and has a bright and extensive ray system. Its name was adopted by the International Astronomical Union (IAU) on April 24, 2012. Nureyev is named for the Soviet and British ballet dancer Rudolf Nureyev.
