Tycho Crater is a prominent lunar impact crater located on the Moon's surface. It is about 85 kilometers (53 miles) in diameter and is known for its well-preserved structure and bright rays that extend outward from the crater. These rays are formed by debris ejected during the impact that created the crater, making it one of the most recognizable features on the Moon. The crater is named after the Danish astronomer Tycho Brahe, who made significant contributions to astronomy in the late 16th century. Tycho Crater is estimated to be around 108 million years old and is a popular target for both amateur and professional astronomers due to its striking appearance and geological significance.
