Crater Fracastorius Video by astronomical telescope. Description and location

Fracastorius (124 km), is the remnant of a lava flooded crater, located at the southern edge of Mare Nectaris. Northwest of the crater formation is Beaumont and north-east is Rosse.

North wall of this crater is missing which gives a form of horseshoe. Mare Nectaris lava invaded the crater, so that looks like a great extension like a golf. The remaining edge is strongly affected and covered by small impact craters. The most prominent of these craters is Fractastorius D, which overlaps part of the western rim.
Maximum altitude of the rim is 2.4 km.
Fracastorius has no central peak, but only a thin crack crossing the middle of the floor from east-west.
The crater is named after the Italian scientist, astronomer and poet Girolamo Fracastoro, "Fracastorius" (1478-1553).
