Jansky is a lunar impact crater that lies along the eastern limb of the Moon. It lies due east of the larger walled plain Neper, along the southern edge of the Mare Marginis. Due to its location, this crater is viewed from the side from Earth, limiting the amount of detail that can be observed. The visibility is also affected by libration, which can completely conceal this formation from view.
This is a worn crater with an eroded rim. The southern part of the rim in particular is disrupted and irregular in form, with a pair of small craters along the inner wall. The remainder of the rim is roughly circular. The interior floor is relatively featureless, except for a few tiny craterlets.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Jansky.

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".
