Crater Posidonius

Post by Christopher K. »

This area is about ninety-five kilometers wide and is located in the northeast quadrant of the near side of the Moon. Its location is sketched on section 14 of Rükl's irreplaceable Atlas of the Moon. I looked at this feature on 18 October at about 7:15pm (5.6 day-old Moon), using a 12.5mm eyepiece with one of the 6" Orion Skyquest Dobsonians. I not only saw Posidonius but Posidonius A and the partial inner wall to the southeast.

This feature is named after the Greek astronomer of BC times.
