Object Name: Copernicus & Erastosthenes craters
Object Type: Lunar Crater
Location: Madrid (Spain). Sketching course at Asociacion Astronomica Madrid Sur (AAMS)
Media: graphite pencil, white paper
Additional information: This sketching was my very first one, produced as a practice during a course managed by local recognized artist Moisés Rojas Cabezudo during an activity of Agrupacion Astronomica Madrid Sur (www.aamadridsur.org). The model was a picture of this lunar area
Copernicus is a lunar impact crater 95kms wide and 3.8kms deep, located in Oceanus Procellarum. It is estimated to be rather young because there is no lava flooding the base of the crater. There is a prominent ray system spreading up to 800kms around.
Eratosthenes is a relatively deep lunar impact crater localted in Mare Imbrium, ending the Apenninus Mons. There is a prominent central peak and terrace walls surrounding the inner walls of the crater.
