With a diameter of 300 km, the lunar crater Bailly is one of the largest whale plains on the moon . It is named after the French astronomer and Paris mayor Jean-Sylvain Bailly (1736–1793), who discovered the drop phenomenon when Venus passed through .
The circular whale plane is close to the southwestern edge of the moon, so that when the light falls appropriately it appears as a very slender ellipse (about 1:10) with smaller secondary craters . If it moves even closer to the edge of the moon with extreme libration , it can sometimes hardly be made out in the maze of craters in the highlands, but with favorable libration it is only distorted in a ratio of about 1: 4.
The large crater is only about 20 ° from the South Pole, the selenographic latitude of the crater center is 66 ° 31 'south, the selenographic longitude 69 ° 32' west.
