Craters last for millions of years on the surface of the moon because the moon does not have an atmosphere. Saying this the moon does not have anything able to fill in the craters such as soil or rain.
Mars' surface features last for billions of years because of its thin atmosphere and minimal erosion processes, such as wind and water. This has helped preserve ancient features like impact craters and volcanoes on the planet's surface.
Craters, mostly. The new Messenger photos of Mercury from just last week show craters on craters, and chains of craters. It looks a lot like the Moon, actually. You can see some photos of Mercury at the link below.
Mercury is the planet that has surface features that can last for billions of years due to its lack of erosion. The lack of an atmosphere and geological activity on Mercury means that impacts from space are the primary process that shapes its surface features.
Ice ages last for some tens of millions of years with intervals of about 150 million years between them. The term is used more loosely to identify the last time that ice sheets covered much of Europe and North America.
Rocks can last for millions to billions of years, so their lifespan is considered to be essentially infinite in human terms.

Craters last for millions of years on the Moon because there is no atmosphere to erode them. On Earth, weathering processes like wind and water can slowly wear away craters, but on the Moon, the lack of atmosphere means that craters remain relatively unchanged for long periods of time. Additionally, the Moon's surface experiences very slow geological processes, further preserving these features.
Craters on the moon last for millions of years because there is no atmosphere to weather or erode them. Without wind or water erosion, the impact features on the moon remain relatively unchanged for long periods of time. Additionally, the lack of tectonic activity means the surface of the moon is not constantly being reshaped.

Lunar craters can last for billions of years, as they are formed by impacts from meteors and asteroids which are infrequent occurrences. The lack of weathering and erosion on the Moon preserves these craters for extended periods of time.

They last much longer than that. Some of the moon's craters are billions of years old. They last so long because there is nothing to erase them. Earth has wind, water glaciers, volcanoes, and tectonic plates to bury, erode, and erase craters. The moon has none of these processes. Some refer to the moon as geologically dead.

It varies, but they appear to last millions to tens of millions of years. The Hawaii hot spot is at least 80 million years old.
