Henyey (crater)
Henyey is a lunar impact crater that lies on the far side of the Moon from the Earth. It is attached at the southern end to the northern rim of the crater Dirichlet. Less than a crater diameter to the northeast is the large crater Mach, and to the northwest lies Mitra.
This is a worn and eroded crater that has been partly disintegrated by subsequent impacts. The elongated crater Henyey U is attached to the western outer rim. The western interior floor of Henyey is disrupted by some small craters.
Henyey lies on the eastern margin of the Dirichlet-Jackson Basin.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Henyey.

1365 Henyey
1365 Henyey, provisional designation 1928 RK, is a stony asteroid from the inner regions of the asteroid belt, about 11 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg Observatory, southern Germany, on 9 September 1928.
The asteroid is a member of the Flora family, a large group of S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,232 days). Its orbit shows an eccentricity of 0.12 and is tilted by 5 degrees to the plane of the ecliptic. It has a rotation period of 18.99 hours and an albedo of 0.28 and 0.24, based on data of the WISE/NEOWISE mission and on assumptions made by the Collaborative Asteroid Lightcurve Link, respectively.
It was named after American astronomer Louis Henyey (1910–1970), known for his contributions in the field of stellar structure and stellar evolution. The lunar crater Henyey is also named in his honour.

Crater (Aden)
Crater (/ˈkreɪtər/; Arabic: كريتر, [ˈkɾeːtəɾ]), also Kraytar, is a district of the Aden Governorate, Yemen. Its official name is Seera (Arabic: صيرة Ṣīrah). It is situated in a crater of an ancient volcano which forms the Shamsan Mountains. In 1991, the population was 70,319. As of 2003, the district had a population of 76,723 people.
In the closing days of British rule in 1967, Crater District became the focus of the Aden Emergency, sometimes called the last imperial war. After a mutiny of hundreds of soldiers in the South Arabian Federation Army on 20 June, all British forces withdrew from the Crater. The Crater was occupied by Arab fighters while British forces blocked off its two main entrances. In July, a British infantry battalion, led by Lt. Col. Colin Mitchell of the Argyll & Sutherland Highlanders, entered the Crater and managed to occupy the entire district overnight with no casualties. Nevertheless, deadly guerrilla attacks soon resumed, with the British leaving Aden by the end of November 1967, earlier than had been planned by British Prime Minister Harold Wilson and without an agreement on the succeeding governance.

The name of the western constellation in modern Chinese is 巨爵座 (jù jué zuò), meaning "the huge wine holder constellation".
