The craters of Theophilus, Cyrillus, and Catharina are prominent lunar features located on the Moon's surface. Theophilus is the largest of the three, measuring about 100 kilometers in diameter and known for its well-preserved structure and central peak. Cyrillus and Catharina are slightly smaller, with diameters of approximately 97 kilometers and 93 kilometers, respectively. These craters are part of the Mare Nectaris region and showcase a variety of geological features. All three craters were formed by ancient impacts and are characterized by their rugged terrain and distinct walls. The surrounding areas contain numerous smaller craters, highlighting the Moon's history of bombardment. Observing these craters provides valuable insights into the Moon's geological past and the processes that shaped its surface.
