Impact Features. Craters are the most widespread landforms in the solar system. Craters are found on all of the terrestrial planets—Mercury, Venus, Earth and Mars. The surfaces of asteroids and the rocky, ice covered moons of the outer gas planets are cratered as well.
Impact craters range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth.
It is distributed outward from the crater’s rim onto the planet’s surface as debris. It can be loose materials or a blanket of debris surrounding the crater, thinning at the outermost regions. Rays – Bright streaks extending away from the crater sometimes for great distances, composed of ejecta material. What are the different kinds of craters?
Formed in a collision 80 million years ago, the Baptistina family of asteroids is thought to have caused a large spike in the impact rate. Note that the rate of impact cratering in the outer Solar System could be different from the inner Solar System.
Where can impact craters be found?
Impact craters are found on most of the solar system’s rocky planets and moons. The so-called “gas giants” of the solar system—Jupiter, Saturn, Uranus, and Neptune—don’t have craters. These planets are made up almost entirely of gases, so there is no hard surface for a meteor to impact.
What country has the most impact craters?

Testing and studying these craters may help NASA identify areas on the Moon that are rich in water and other resources to determine how to best use those materials while on the lunar surface.
Why are there more impact craters on the Moon than there are on … – Quora
Volcanoes, plate tectonics, glacier movement, vegetation, people, flooding, and winds all act as erosion forces upon craters on the Earth, smoothing them over, filling them in, and overgrowing them. Our oceans and atmosphere absorb much of their energy. Small objects are often vaporized while descending through our atmosphere. Quora User

On Mars, impact craters are a key focus in the hunt for the planet’s warmer, wetter past. Rocks ejected by impacts contain minerals that formed in the presence of liquid water; some craters also show signs of ancient lakes. Layered sediments in the rims of craters bolster the evidence that Mars not only had flowing water, but a complex water cycle.
