Mercury is a small planet that is quite hot (approximately 800°F [427°C] during a Mercurian day) when the Sun shines on its surface. It has a very thin atmosphere of oxygen, potassium, and sodium vapors. The surface pressure of atmosphere is too low to have wind. Without wind, running water, and flowing ice, the range of surface processes is limited to physical weathering effects of heating and cooling and meteoritic impact.
Mariner 10 is the only spacecraft to have photographed the surface of Mercury. Completing a total of three close encounters with the planet, in March and September 1974, and March 1975, the space probe was able to record details over about 45% of Mercury's crater strewn surface. The remaining half of Mercury's surface has never been photographed.
Mercury's surface is very similar to that of the Moon. There are, however, some important differences This expanse of the surface of Mercury is about 217 mi (350 km) across. These inter-crater plains, located near the south pole, are traversed by numerous ridges and scarps. The crustal fracturing on Mercury is as large in scale as that on Earth. U.S. National Aeronautics and Space Administration (NASA). in features. Mercury has, for example, relatively fewer craters larger than 15.5-31 mi (25-50 km) in diameter. There are no extensive highland regions on Mercury, and the surface is subdivided simply into "cratered terrain" and "intercrater plains" based upon differences in crater density and size. Resurfaced regions on Mercury are rare (<15% of the surface), and are referred to as "smooth plains." Unlike the Moon, Mercury exhibits many scalloped cliffs, or lobate scarps that can run for several hundred kilometers and be as much as 0.6 mi (1 km) high. Only one lunar-like mare, the Caloris Basin, has been discovered on Mercury, however, many large multi-ring crater basins (124-373 mi [200-600 km] in diameter) are filled with flood basalts like the lunar mare. Sporting a relatively flat but wrinkled floor, and being surrounded by a ring of 1.24 mi-(2 km) high mountains, the Caloris Basin, with a diameter of about 807.5 mi (1,300 km), is the largest Mercurian feature.

What planet has surface features that last for billions of years because a little erosion?
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.

What are 3 noticeable features that are found on the surface of mercury?
Three noticeable features found on the surface of Mercury are vast impact craters caused by collisions with asteroids and comets, long scarps or cliffs that suggest the planet has shrunk over time, and smooth plains formed by volcanic activity.
What are Mercury's landforms?
Mercury's surface features include craters, plains, scarps (cliff-like landforms), and ridges. It also has a large basin called the Caloris Basin, which is one of the largest impact features in the solar system.
