The lunar crater Bailly is 300 km across one of the largest Wall plains on the moon. It is named after the French astronomer and Paris Mayor Jean -Sylvain Bailly (1736-1793), who discovered the drop phenomenon at the transit of Venus.

The circular wall level is close to the southwestern edge of the moon, so that it appears at a suitable light as a very slender ellipse ( about 1:10 ), lie in the smaller secondary craters. If they are still closer to the edge of the moon in extreme libration, it is sometimes difficult to discern in the crater tangle of the highlands, with a favorable libration distorted but only approximately in the ratio 1:4.

The large crater is only about 20 ° away from the pole, the selenografische width of the center of the crater is 66 ° 31 ' South, the length selenografische 69 ° 32' West.
