Understanding the processes occurring on Ceres is important because the dwarf planet is one of the most well-studied bodies in the Solar System. It is also one of the few bodies that has been visited by a spacecraft, NASA’s Dawn mission, which orbited Ceres from 2015 to 2018.
One of the things that Dawn observed on Ceres was the presence of numerous impact craters. These craters are formed when objects from space, such as asteroids or comets, collide with the dwarf planet’s surface.
Dawn also observed that many of these impact craters are relatively shallow. This suggests that the material that falls onto Ceres does not rebound as much as it does on other objects in the Solar System.
The new study, published in the journal Icarus, provides an explanation for this difference. The researchers used a computer model to simulate impacts on Ceres. The model showed that the material that falls onto Ceres does not rebound as much as it does on other objects in the Solar System because Ceres’s gravity pulls it back to the surface.
This finding has implications for our understanding of the evolution of the surfaces of planetary bodies. It also provides insights into the processes that may have occurred on Earth early in its history, when the planet was more heavily bombarded by asteroids and comets.
