Impact craters
The large circular features on a moon's surface are typically impact craters formed by the impact of meteoroids or asteroids. These craters are created when an object collides with the moon's surface at high velocity, excavating material and forming a circular depression.
The moons surface has mountainous highlands and large circular plains. The circular plains are called Maria. The mountain has heights up to 25000 feet.
The feature covering much of the moon's surface is the lunar mare, which are large dark plains formed by ancient volcanic activity. These mare areas are less cratered compared to the highlands and are thought to be composed of basalt rock.

No. Io is one of the four major moons of Jupiter. The moons of Mars are Phobos and Deimos.
A Crater Craters are the most common surface features on many solid planets and moons—Mercury and our Moon are covered with craters. Craters are roughly circular, excavated holes made by impact events. The circular shape is due to material flying out in all directions as a result of the explosion upon impact, not a result of the impactor having a circular shape (almost no impactors are spherical)
Titan and Triton are both large moons with thick atmospheres. They have surface features such as lakes and cryovolcanoes that suggest geologic activity. Both moons also have abundant sources of methane.
The three main features of Jupiter are it's large red spot, the banding formed by weather patterns and it four large moons. There are loads of other features, but these are probably the main ones when observing from earth.
Jupiter has four large moons known as the Galilean moons. These moons are Io, Europa, Ganymede, and Callisto. They are considered important because of their size, unique features, and potential for scientific study.
The moon's surface is mainly covered by cratered highlands and large basins called maria, which are dark, flat plains formed by ancient volcanic activity. Other features include rilles, which are long, narrow depressions, and impact craters of various sizes caused by meteorite strikes.
