We conclude that something must be renewing or eroding the surface.

What do you conclude if a planet has few craters of any size?
Its surface is relatively young and therefore that there are internal mechanisms that are or have been recycling the surface.
How does a planet's atmosphere affect its number of impact craters?
An atmosphere will lessen both the amount and size of impact craters by burning meteoroids so they get smaller or even disappear entirely. If there is no atmosphere, the object will simply hit the planet or moon with no reduction in its size. Earth's atmosphere does this because the air molecules create friction when the meteoroid passes through it. The friction is hot enough to burn the meteoroid up entirely or at least down in size. An atmosphere means fewer and smaller meteoroids. (When a meteoroid does make it to the ground, it then is called a meteorite.)
What are two variables that could cause meteorites to form different sized craters?
There are a number of factors that determine the size and shape of a crater. The two most significant are the mass of the impactor, and the speed. Other influential factors would include the composition of the object (solid rock or more aggregate, like pebbles? Ice?) the shape of the object, and the composition of the impact site. If it is on dry land, it will be more likely to leave a visible crater, while a water or marshy impact site would be quickly erased. If a water impact, the depth of the water and the topography of the surrounding seas would be vastly important. A strike in a deep ocean basin might be relatively mild, while a water strike in the South China Sea or Gulf of Mexico, with the constricted water flow, might result in catastrophic tsunamis inundating the surrounding areas.
Why do some planets have craters?
The shape and size of a crater is dependent on the speed, size, and direction of the object that made the crater. Try tossing some big and little rocks or balls into some soft dirt or sand and see what happens!
Does the mass of a planet equal the size?
No, the mass of a planet does not equal the size of that particular planet.
What do you conclude if a planet has few impact craters of any size?
Atmospheric density would be a factor affecting the number of impacts on a planetary body.

When meteors or other objects stike the moon what do they create?
Impact craters. The size of the crater is related to the speed of the impact and the size of the object.
What are the wholes in the Moon's sufrace caused by?
By "wholes" I assume you mean craters. Most of the moons craters are caused by meteorite impact of varying size.
How do craters occur?
Craters occur when flying objects in space crash onto a planet. Then, depending on the size of the crater, a large depression-like hole will form.
The planet that is most compared to the moon?
Mercury. Both are approx the same size, and both are covered with craters.
What causes impact?
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
Does the moon have a lot of craters?
Yes. This is because the moon has no atmosphere, bodies such as meteors do not burn up like they do on Earth. Because of this, these bodies hit the moon in their full size and, due both to the size of the body and the speed at which they are moving, they leave craters upon impact.
What can you infer from studying the dpths and diameters of craters on the moon?
By studying the depth and diameters of the moon's craters, an impact specialist could determine the size of the object that hit the moon, give a good estimate of the velocity of the object, and approximate where it originated from in the sky.

Does the size of a planet has any impact on the eccentricity of a planets orbit?
No but the sizes of OTHER planets and planetesimals can and do.
What happened when an asteroid hits the Earth?
depending on the size it could destroy the planet or impact in the water and not do much. It all depends on the size of said asteroid!
