More craters formed 4 to 5 billion years ago because during that time, the solar system was still forming and there was a higher rate of impacts by asteroids and comets. This period is known as the "Late Heavy Bombardment" where the inner planets, including Earth, were bombarded with debris left over from the formation of the solar system.

Why did craters form 4 to 5 billion years ago?
Craters formed 4 to 5 billion years ago due to intense bombardment of the early solar system by asteroids and comets. During this period, the surface of planets and moons, including Earth, experienced frequent impacts that created large craters. These impacts gradually decreased as the solar system stabilized.
Why can THEY still see craters on the moon?
Anyone can see craters on the moon. All you have to do is look at it when it's in the sky. There are billions of craters on the lunar surface with more being added almost daily. There will always be craters on the moon because there is no atmosphere to erode them. The lunar craters only form of erosion is from solar bombardment and being hit by another object.
When did Mercury get craters?
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.
Approximately how much older are prokaryotes than eukaryotes?
Prokaryotes are estimated to have been around for about 3.8 billion years, while eukaryotes are thought to have evolved around 1.6 billion years ago. Therefore, prokaryotes are approximately 2.2 billion years older than eukaryotes.
Would a planet with active or less active volcanoes have more craters?
A planet with fewer active volcanoes would have more craters, as the ash and lava from volcanoes will cover existing craters.

Craters formed 4 to 5 billion years ago due to intense bombardment of the early solar system by asteroids and comets. During this period, the surface of planets and moons, including Earth, experienced frequent impacts that created large craters. These impacts gradually decreased as the solar system stabilized.
What are the saucer like depressions on the moon's surface called?
They are called "craters" and were produced by meteor impacts (the vast majority more than 2 billion years ago).
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.
When did the meteors crash into the moon?
The "high impact" period of our solar systems development seems to have been heavily concentrated in the first 500 million years. By the time the solar system was 500 million years old, (4 billion years ago), the "high impact" period was slowing down. There was a "last hurrah" from 4 billion year ago to 3.8 billion years ago, then it virtually stopped. Almost all the notable craters on the moon's surface were created by impact more than 3.8 billion years ago, according to current astronomical thought.
Who has more craters the earth or the moon?
there are more craters on the moon then on earth
Is the earth more than 6 billion years old?
No. The current best estimate is about 4.6 billion years.

What has existed for at least 3 million years?
The universe has existed for more than 14 billion years, the sun for more than 4 billion years - both well over 3 million years.
How long ago did earth and your solar system form?
About 4.5 to 4.7 billion years ago. It's difficult to determine it more precisely; we weren't there.
What did the moon look like one billion years ago?
One billion years ago, the moon would have appeared much closer to Earth due to tidal braking (slowing down of the moon's rotation). It would have a stronger gravitational influence on the Earth causing higher tides. The moon's surface would have been more geologically active, with more frequent volcanic activity and impacts.
How old are the moons craters?
The number of craters on the moon are too many to count. Approximately 300,000 craters with diameters of 1 km or more are visible from ground based telescopes. High-definition photographs from lunar probes reveal millions of craters. Extreme closeups show countless microscopic craters.
Do the craters cause more gravity on the moon?
No. The craters on the moon do not affect its gravity.
