Are there more craters on Mercury and the Moon than the Earth?
The surface of the Earth has been reworked over geological time and this has erased evidence for craters that have existed on the Earth. However all the inner planets and moons have been subject to the same rate of impactors and as Earth is larger, it is therefore likely that Earth has in fact received more impactors (and therefore had more total craters) than the Moon or Mercury. There are more craters now visible on the Moon and Mercury, but there were likely many more on the Earth over the same astronomical time. But craters on Earth have become less visible due to erosion and geologic activity - these processes are much more active on Earth than on the Moon or Mercury, which have less tectonic activity, no real atmosphere, and no liquid water.
Why is the moon and mercury so much more cratered than the earth?
The Moon and Mercury have more craters because they lack significant geological processes like tectonic activity and erosion that constantly reshape the Earth's surface, resulting in the preservation of impact craters. The absence of atmospheres on the Moon and Mercury also means there is no protection from incoming asteroids and meteoroids, leading to more impact events and crater formation.
Does the moon has more craters than the earth?
Yes it does. The Moon has no air to stop meteors.
Which planet is less than half the diameter of the earth and looks like your own moon?
Mercury. Its surface is covered with impact craters similar to those on Earth's moon. Its diameter is approximately 4879 km while Earth's is ~12,742 km
Is Mercury smaller than the Moon?
Jupiter has more than 60 moons. Ganymede is the largest and it's diameter is 5,262 km (3,268 mi). The second largest moon is Callisto with a diameter of 4,806 km. Mercury's diameter is about 4,880 km.

Why are impact craters on Earth harder to see than those on Mercury or the Moon?
Unlike Mercury of the moon, Earth is geologically active. Erosion, deposition, and plate tectonics have buried or destroyed most of Earth's craters.

What is unusual about the moon Io?
the moon is smaller and has lots more craters than earth does and night lasts longer on the moon
Why do moon craters remain visible longer than earth craters?
There is no significant amount of erosion on the Moon.
What does a planets like mercury have more craters than the earth?
In the earliest days of our solar system (which I like to call the "Demolition Derby epoch") earth probably had as many or more craters than Mercury did. But earth developed weather, which over the millennia, wore the craters away. Mercury never had weather, so it's craters remain untouched today.

Mercury. Its surface is covered with impact craters similar to those on Earth's moon. Its diameter is approximately 4879 km while Earth's is ~12,742 km
Why more craters are present on the Moon's surface than on Earth's?
because the moon does not have a equater like the earth to protact it self ;)
When did the majority of the craters on mercury form?
Most of the craters probably formed when the solar system was young and large impacts were far more common than they are now.
What moon of Jupiter is bigger than mercury?
Both Titan and Ganymede are larger than Mercury and Pluto.
What is the main reason that impact craters on the Moon last much longer than impact craters on earth?
Impact craters on the moon have no water/weather to erode the craters away, but on Earth the erosion erases the craters over time.
