Ansgarius is a
lunar impact crater that is located near the eastern limb of the Moon. When viewed from the Earth, the crater has a highly oval shape due to foreshortening, but the rim is actually nearly circular. To the northwest of Ansgarius is the crater La Pérouse, and south is Behaim
.
The rim of Ansgarius is not significantly worn, and has a
Saint Ansgar
, a 9th-century Benedictine missionary monk who brought Catholicism to northern Germany and Scandinavia, known as the "Apostle of the North".
The crater's name was approved by the IAU in 1935.[1]
