Landau is a large lunar crater that is located in the northern hemisphere on the far side of the Moon. It was named after physicist Lev Landau. The crater Wegener is attached to the northeastern rim. Attached to the southeastern rim is Frost.
The outer rim of Landau is heavily eroded and modified by subsequent impacts. The most notable of these is Wood, which overlays the northwest rim. Much of the floor is hilly and irregular, with only the northeast quadrant being somewhat level. There are multiple small craters and craterlets in the floor. The most intact section of the rim is in the southwest, although this is now little more than a low ridge line.
Landau lies at the approximate margin of the Coulomb-Sarton Basin, a 530 km wide impact crater of Pre-Nectarian age.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Landau.

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.
According to traditional Chinese uranography, the modern constellation Crater is located within the southern quadrant of the sky, which is symbolized as the Vermilion Bird of the South (南方朱雀, Nán Fāng Zhū Què).
The name of the western constellation in modern Chinese is 巨爵座 (jù jué zuò), meaning "the huge wine holder constellation".
