because the planet has a way to reform it self every millions of years

No. Almost all large solid objects in the solar system have craters.
The moons surface is covered with craters, caused by asteroid collisions early in the history of the solar system. The large dark patches on the moon, are seas of lava that flowed out of the moon's interior, filled the impact craters, and cooled to solid rock.
Like all major bodies on the solar system, the moon has been hit by many asteroids and comets. Most of the large impacts were when the solar system was young. Unlike some of the other worlds such as Earth, however, the moon has no geologic activity, no atmosphere, and no water to bury or wear down those craters.
The early days of the solar system were much like a demolition derby of meteoroids slamming into other bodies. Earth was pummeled just as severely as the moon was, but earth has weather - which softens and erodes the craters over time. The moon, with no weather, keeps it's many craters intact.

Yes. All major bodies in the solar system have been hit by metorites. Mercury's surface is covered with impact craters.
Craters can be the result of volcanic activity or from external impact events (bodies from space striking the planet or moon).
There are many bodies in our solar system with craters exceeding 5 km. across - they are common. Venus is merely typical in that regard.
Asteroids, meteorites or comets are impactors that form impact craters on the Earth and other bodies throughout the solar system. Obviously, the Earth for instance, has to cross an impactor's orbit or vice versa. The size of the impactor hitting the Earth depends on the type of crater that can occur and also the other factors- · the velocity of the impactor · composition of the impactor · composition of the target rock · the strength and porosity of the impactor · angle of impact · gravity of the target planet For more on craters try- www.weirdwarp.com
Many impact craters are visible on many planets and satellites of planets. The moon is a perfect example, it is covered with craters, some of which we can see from Earth even without a telescope. We do have a few impact craters that have survived here on Earth, as well, even though the weather on Earth, over long periods of time, tends to smooth away craters.
Any fairly large rocky body with no atmosphere. In our solar system, the Moon and Mercury both fit this description.
Earth does have impact craters, but it has much few than the moon or Mercury and many of them are not readily visible. The main reason is that Earth has many active geologic processes that renew and change its surface, burying and destroying impact craters. If an impact crater on Earth is clearly visible then it probably formed quite recently in geologic history. Many of the impact craters on the moon and Mercury are billions of years old, dating to when the solar system was young and large asteroid impacts were far more common than they are now. Very little of Earth's crust from that time remains intact. By contrast craters on Earth that are tens of millions of years old are not readily visible.
Moons and planets have craters because they are constintly hit by space junk. Things like asteroids, pieces of rock, and, sometimes, comets. A comet impact is very rare and unlikley to happen. Our solar system has only experienced one comet impact that we know of, and it wasn't on earth.
Craters don't hit anything. A crater is a hole or dent left by an explosion or a collision. Although Pluto has never been photographed with enough detail to see any craters, there is no doubt that it has them as all major bodies in the solar system experience collisions and Pluto is in a region where it has a fair chance of colliding with comets.
In all likelihood, yes. Most large solar system bodies have been heavily bombarded by asteroids and there is no reason to believe Makemake is an exception. However, Makemake is so far away that we cannot make out enough detail to see any craters.
