Geological Chronicle

Euler lies in the southern half of Mare Imbrium. Mons Vinogradov is west-southwest, while a cluster of low ridges lies to the southwest and includes the small crater Natasha and tiny Jehan. Lambert, a comparably sized crater, lies about 200 kilometers to the east-northeast.

Euler dates to the Eratosthenian age. A low rampart surrounds its rim, which has some slight terracing and slumped features along an irregular inner wall.

At the center of the small interior floor, a low central peak formed from rebound after the impact. Euler also has a minor system of rays extending 200 kilometers. The crater is named for Swiss mathematician, physicist and astronomer Leonhard Euler.
