Further to the east-northeast is the large crater Gauss, and to the north-northwest lies Bernoulli.

The rim of this crater is roughly circular, but with some angularity along the eastern edge.

The southern end of the crater has been heavily eroded, and there are some tiny craterlets along the northern rim.

The interior floor of Berosus has been flooded by lava, and so is level and nearly featureless.

[1] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Berosus.
