Eponym Gaius Sulpicius Gallus

Sulpicius Gallus is a small, bowl-shaped lunar impact crater that lies near the southwestern edge of the Mare Serenitatis. Nearby craters include Bobillier to the northeast and Menelaus to the southeast along with Daubrée.

The crater is named after the Roman Gaius Sulpicius Gallus.[1]

Description[edit]

About 10 kilometers to the south and east is the Montes Haemus range that forms the edge of the Serenitatis basin. This crater has a relatively high albedo, with a sharp-edged rim that displays little appearance of wear. There is a small rise at the midpoint. Recent deposits of highland material have been observed within the crater interior. East is a wrinkly ridge known as Dorsa Sorby.

Rimae Sulpicius Gallus

To the northwest is a rille system designated the Rimae Sulpicius Gallus. These extend to the northwest for a distance of about 90 kilometers, curving and branching out to follow the edge of the mare.

Being located at the 19th parallel north area, The Earth mainly appears at the lunar sky at around 71 degrees facing south and 10 degrees towards the west from the top. Also, the sun rises before or during the third quarter of Earthshine and the sun sets during its first quarter.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Sulpicius Gallus. Sulpicius Gallus A is located to the north-northwest, Sulpicius Gallus B is located nearly to the south, Sulpicius Gallus G and H are located further west-northwest and Sulpicius Gallus M is located in between.
