Description
Brouwer is a crater of the Nectarian period (~ 3.92 to 3.85 bn years) and lies just off the north-eastern sector of the South Pole Aitken Basin -- a 2500 kilometre-wide basin of the pre-Nectarian period (~ 4.6 to 3.92 bn years). The rim of Brouwer is barely perceptible in the above image as most of it is well worn down through age and through minor impacts, however, its old appearance and impercibility, undoubtedly, also pays tribute to influence from ejecta deposits from the Orientale Basin -- a basin of the Imbrium period (3.85 - 3.15 bn years) -- lying just north-east of the crater. Rim-collapsed material has filled most of the eastern floor of Brouwer, while its western sector has been interrupted by a major impact producing Langmuir crater. For a complex crater having an approximate diameter of 158 km, Brouwer's central region lacks a peak, however, would the crater (~ 25 km) at the centre of the floor be responsble for obliteration of this missing peak?- JohnMoore2 JohnMoore2
