The South Pole-Aitken basin (not "Aitken crater") on the far side of the moon, at 1,600 miles across, is not only the largest known impact crater on the moon but one of the largest in the solar system. It is also believed to be the moon's oldest and deepest (over 8 miles deep).

Beethoven is a crater at latitude 20°S, longitude 124°W on Mercury. It is 643 km in diameter and was named after Ludwig van Beethoven.[1][note 1] It is the eleventh largest named impact crater in the Solar System and the third largest on Mercury.

Galileo discovered Jupiter's 4 largest moons, the Galilean moons. The largest moon's name is Ganymede.
Jupiter is the largest planet in our solar system, and it has 63 known moons.
Saturn has 53 known moons and 9 provisional moons, and its largest moon is called Titan. Titan is the second largest moon in the entire solar system.
The oldest crater found on the moon is thought to be the South Pole-Aitken basin, which is estimated to be around 4 billion years old. It is one of the largest and deepest impact craters in the solar system, spanning over 2,500 kilometers in diameter.
Saturn's moon with the crater Herschel is called Mimas. Mimas is one of Saturn's innermost moons and is known for its large Herschel crater, which gives it a distinctive "Death Star" appearance.
The material that stacks around the edge of an impact crater on the Moon is called "crater rim ejecta" or simply "ejecta." This material is composed of debris that is ejected outward during the impact event and can form a raised rim around the crater. The thickness and extent of this ejecta can vary depending on the size of the impact and the characteristics of the lunar surface.
