Old craters tend to have smoother edges and floors due to erosion and infilling over time. They may also have been partially erased or modified by tectonic or volcanic activity, making them less distinct. Studying the surrounding geological features and conducting dating methods on the crater materials can also provide clues to their age.
Old craters typically have more erosion, with smoother edges and a shallower depth compared to new craters. New craters have sharp, well-defined edges with steep walls and a more prominent central peak. Additionally, the presence or absence of overlapping craters can also help distinguish between old and new craters.
Depends on which kind of craters you are thinking about. Craters aren't important as such. But impact craters tell us that not all things in space stays nicely in their expected positions. Some drift around and occasionally collide with planets, causing impact crates and other damage. Volcanic craters tells us that the planet has some seismic activity.

Unlike Earth, the moon does not have air, water, glaciers, or plate tectonics to erase craters. The only forces that significantly alter the moon's surfaces are impacts that form new craters.
Yes, the planet Venus has craters on its surface, although they are not as common as on other planets like the Moon or Mars. The dense atmosphere and volcanic activity on Venus have erased many of the smaller craters over time.
The maria (large, dark, flat plains formed by ancient volcanic activity) on the moon are younger than the craters (impact sites from asteroids or meteoroids). The maria are estimated to be around 3 billion years old, while many of the craters are thought to be upwards of 4 billion years old.

Each crater on Mercury was left behind by an asteroid or comet that collided with it. Many of the craters are nearly as old as the planet itself, as collisions were far more common when the solar system was young. Other craters may only be a few million years old.
The moon has no atmosphere, liquid water, or plate tectonics and little volcanic activity or bury, erode, and southwester destroy impact craters.
old, dusty and full of craters
If there are lots of craters, it means there is no significant atmosphere. The reason is that any craters will be eroded eventually, by the presence of an atmosphere.

Phobos and Deimos are the two moons of Mars. They are small and shaped irregularly. The surfaces are scarred by many large impact craters. This is why the moons are extremely old.

There are several lunar features that are visible to the naked eye, and more are visible with even a very small telescope.The craters are probably the most obvious; circular impact craters caused by the collision of some very large asteroids or comets have created circular mountain ranges that are hundreds of miles in diameter. There are craters in craters, craters ON craters, and chains of craters. Because the Moon lacks an atmosphere, there are no erosive forces to break down and hide the craters (as there is here on Earth) and so the only thing wearing away the old craters are ..... new craters!Lunar craters are usually named for astronomers and scientists.The other major features of the Moon are the maria, or seas. Originally believed to be oceans and seas of water by classical observers, we now believe that they were made by lava flows.
There are hundreds. Probably the most obvious is the Barringer Meteor Crater in Winslow, Arizona, USA, but there are craters all over. Many of them are so old and so enormous that we didn't realize they were ancient craters until we saw satellite photos of them.
