Brouwer (crater)

Brouwer is a large lunar crater that is located in the southern hemisphere on the far side of the Moon. Intruding into the western rim of Brouwer is the younger and somewhat smaller crater Langmuir. Further to the east-southeast is the larger walled plain Blackett.

This is an old crater formation with a rim that has been heavily worn due to subsequent impacts. Parts of the rim to the east and north can still be traced in the irregular terrain, but the southern rim is almost completely disintegrated. The interior floor is rough in the southeastern half, and somewhat more level and less rough to the northwest. Lying just to the southeast of the crater midpoint is the satellite crater Brouwer H. If the floor once possessed a central peak, it may have been overlaid by this last-mentioned formation.

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 Brouwer.

1746 Brouwer

1746 Brouwer, provisional designation 1963 RF, is a dark, reddish Hildian asteroid from the outermost region of the asteroid belt, about 64 kilometers in diameter. It was discovered on September 14, 1963 by the Indiana Asteroid Program at the U.S. Goethe Link Observatory near Brooklyn, Indiana.

The asteroid is a member of the Hilda family, a large group that orbits in resonance with the gas giant Jupiter and are thought to originate from the Kuiper belt. The body orbits the Sun at a distance of 3.1–4.8 AU once every 7 years and 10 months (2,867 days). Its orbit shows an eccentricity of 0.21 and is tilted by 8 degrees to the plane of the ecliptic. It has a rotation period of 19.8 hours. The reddish D-type asteroid has a low albedo of 0.05, based on observations made by the space-based IRAS, Akari and WISE/NEOWISE missions.

It was named in honor of Dutch–American astronomer Dirk Brouwer (1902–1966). Originally at Leiden University and specialized in celestial mechanics, he became director of the Yale University Observatory and was the president of IAU's commission 20, Positions & Motions of Minor Planets, Comets & Satellites, from 1948 to 1955.
