Mars
Yes, holes in planets can be made by asteroids. When asteroids collide with planets, they can create impact craters that can range in size from small to very large, shaping the planet's surface over time. These impact events can have a significant influence on the geology and landscape of a planet.
Mercury, Venus, Earth, and Mars all have impact craters.
I think it is Mercury.
There are a huge number of craters on the Earth, including very small impact sites. There are about 65 named and documented craters on the planet.
Mercury is the planet with the most visible craters in our solar system. Its surface is heavily pocked with impact craters due to its lack of atmosphere to protect it from incoming space debris.
There is no terrestrial planet without craters.
There will be few impact 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.

Mercury is the planet that is covered with craters cut through by cliffs. Its surface is rugged and scarred with impact craters caused by collisions with asteroids and comets. The planet's cliffs, such as the prominent of its kind called "Great cliffs," are thought to have formed as a result of the planet's shrinking due to cooling.
Nothing. There are no craters on Neptune. Neptune is a gas giant, meaning it has no solid surface. With no solid surface nothing can impact against the planet.
The surface of Mercury is covered with craters, plains, and ridges. It also has volcanic plains and impact craters formed by collisions with asteroids and comets. The planet's surface is rocky and heavily cratered due to its lack of atmosphere to protect it from impacts.
If a planet has few impact craters of any size, it could indicate that the planet's surface is relatively young or has been resurfaced by geological activity such as volcanism, erosion, or tectonic processes. Alternatively, the lack of impact craters could suggest that the planet's atmosphere is thick enough to burn up or deflect incoming asteroids and meteoroids before they reach the surface.
