Scientists know, not think, Neptune has zero craters.
Neptune is a gas giant. Gas giants do not have a solid rocky surface. Therefore nothing can impact against the planet to form craters.
Scientists can see Neptune with telescopes. Also, they have many photos of it from when the Voyager 2 passed by.
The moon is known for having many craters. Some of the craters have been given names by various astronomers and scientists, based on explorations of the moon done by NASA
The reason that this was that it was once the only thing that scientists could use to explain why the moon had so many craters on it (which we now know to be the product of meteorite and asteroid collisions).
Yes, Triton, a moon of Neptune, does have impact craters on its surface. These craters are evidence of past collisions with other objects in space. Many of Triton's craters are relatively well-preserved due to the lack of significant geological activity on its surface.
72 craters are on mars. And a few more, I think.
There are 375 craters in the moon.....
Because the Moon has so many impact craters, scientists believe that this was caused by meteoroids, asteroids, and comets colliding into its surface at an average speed of 20 kilometers per second. The Moon's surface has millions of both simple and complex impact craters.
Currently, Neptune has 13 known moons, or satellites. Technology is making it easier for scientists to discover more about deep space so more may be uncovered in the future.
Neptune has three main rings but all in all it has four total rings. I cannot make up the names right now but I do know that they are named after the scientists who discovered them.
Meteorites. They hit the moon frequently, causing many craters.
There are lots of craters on Mercury. For a more precise answer, we would first want to specify the size, by asking for example how many craters of at least one meter in diameter are there on Mercury.
An asteroid has many craters because each asteroid was a big rock that broke into many peices
