Far Side Southern Crater

A Heavily Eroded Impact Crater on the Far Side

Spanning 93.75 kilometers across the southern far side, Berlage retains a worn rim marked by a high density of smaller craters.

Geological Chronicle

Berlage is an old lunar impact crater located in the southern hemisphere on the far side of the Moon. Mapped within quadrangle LAC-133 (Minkowski), the feature spans 93.75 kilometers across. Several far-side craters lie nearby: the smaller crater Bellinsgauzen attaches to its northern rim, Cabannes sits less than one crater diameter to the northwest, and Lemaître lies to the east-northeast.

On the lunar geologic timescale, Berlage dates to the Pre-Nectarian period. The crater is heavily eroded, its original features worn down with time. It is unusual for the high density of small impact craters that lie across the interior and along the rim, especially across the northern half. Where Berlage joins Bellinsgauzen, a cluster of three small craters sits across the eastern edge of the northern rim.

The crater is named after Dutch geophysicist and meteorologist Hendrik Petrus Berlage (1896-1968), an expert on the Southern Oscillation climate phenomenon. The International Astronomical Union formally adopted the name in 1970.

Chronology & Exploration

  1. Pre-Nectarian Crater Formation

    Berlage forms during the Pre-Nectarian period on the lunar geologic timescale.

  2. Post-Formation Impact Degradation

    Ongoing impacts erode the crater, leaving a high density of small craters across its interior and rim.

  3. 1970 IAU Adoption

    The International Astronomical Union formally adopts the designation Berlage.
