Joy's crater ( lat. Gioja ), not to be confused with the crater Joy ( lat. Joy ) - a large impact crater in the north pole on the visible side of the moon . The name was given in honor of the fictional Italian sailor and inventor Flavio Joy (XIV century) and approved by the International Astronomical Union in 1935. The formation of the crater dates back to the nectar period [1] .

Crater Description
The nearest neighbors of the crater are the Baird crater in the north (Joey's crater overlaps the south-western part of its shaft); Crater De Sitter in the southeast, as well as crater Maine in the south-southeast [2] . The selenographic coordinates of the center of the crater are , diameter 42.5 km [3] , depth 1.63 km [4] .
The crater is close to a circular cup shape, moderately destroyed. The sharp high shaft is blocked by many small craters. The height of the ramp above the surrounding terrain reaches 1260 m in the western part and up to 2150 m at the junction with the Byrd crater [1] , the volume of the crater is approximately 1300 km³ [5] . The bottom of the crater bowl is even, dotted with many small craters, a pair of craters in the northwestern part of the bowl is especially noticeable. The place of the central peak is occupied by a low ridge beginning in the center of the bowl and stretching to the north-northeast section of the inner slope.
