The usual term is crater. Most craters are nearly circular holes surrounded by rims of ejected material. The term "impact basin" is used for the multiple-ringed structures formed by large impacts.
A crater is a bowl-shaped depression on the surface of a planet or moon, usually caused by the impact of a meteorite or asteroid. Craters can vary in size and depth, and can be found on various celestial bodies in our solar system.

It is a type of large crater (surface depression or pit) left on the surface of a moon or planet, caused by a large object striking its surface. It may include concentric rings or flows of melted rock.(see also the related link for a video on craters produced in a lab)
The hole in the ground caused by a meteor hitting a planet is called an impact crater. These craters are formed when a meteoroid, asteroid, or comet collides with the surface of a planet or moon, creating a bowl-shaped depression. The size of the impact crater depends on the size and speed of the impacting object.

The word "meteor" refers to the streak of light in the sky caused when something falls into the Earth's atmosphere at very high speed, and is heated to incandescence by friction and compressive heating. The "something" can be a rock the size of a grain of rice, or anything larger. Before it hits the atmosphere, it is referred to as a "meteoroid"; if it survives to strike the Earth, the fragments if found are called "meteorites". An asteroid is a chunk of rock floating in space, orbiting the Sun. The term can be applied to anything large enough to be visible, but is typically applied to rocks at least a few meters in diameter. There's a lot of gray area between "meteoroid" and "asteroid".
When an asteroid, comet, or meteorite collides with the Moon a crater is formed.
Some asteroids have natural cavities or depressions on their surface, but they are not typically "holes" in the sense of having passageways through them. These features can be caused by impacts or the gravitational forces acting on the asteroid.
They are referred to as impact craters.

The Copernicus crater on the moon was formed by a large impact event, likely from an asteroid or comet colliding with the lunar surface. The impact created a circular depression that we see as the crater today.
