Richards is a small lunar impact crater that is located in the northern interior of the walled plain Mendeleev, on the far side of the Moon. It lies about half-way between the craters Bergman to the west-southwest and Fischer to the east, both also within Mendeleev's interior.
This is a circular, cup-shaped crater with a small interior floor at the mid-point of the sloping inner walls. The interior sides have a higher albedo than the surroundings. There is a small craterlet situated along the north-northeastern edge of the rim. The crater chain named Catena Mendeleev passes just to the west of Richards, continuing in a line of small craterlets from the southwestern edge of Mendeleev.

Lunar craters
Lunar craters are craters on Earth's Moon. The Moon's surface has many craters, almost all of which were formed by impacts.
History
The word crater was adopted by Galileo from the Greek word for vessel - (Κρατήρ a Greek vessel used to mix wine and water). Galileo built his first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions, the latter of which he gave the name craters.
Scientific opinion as to the origin of craters swung back and forth over the ensuing centuries. The competing theories were (a) volcanic eruptions blasting holes in the Moon, (b) meteoric impact, (c) a theory known as the Welteislehre developed in Germany between the two World Wars which suggested glacial action creating the craters.
Evidence collected during the Apollo Project and from unmanned spacecraft of the same period proved conclusively that meteoric impact, or impact by asteroids for larger craters, was the origin of almost all lunar craters, and by implication, most craters on other bodies as well.

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.
Crater (Chinese astronomy)
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".
