Ynet reports that the surfaces of the many rocky planets and moons in the solar system are covered with craters. The vast majority of these craters were created by highly powerful impacts of asteroids and commits, and studying them can provide insight into the processes that shaped the solar system throughout its long history. 

Alongside these visible craters, there are also hidden craters in the form of deep and wide depressions that were formed in entirely different ways, some of which remain unexplained. Understanding the processes that led to the formation of these unique depressions may help us learn about the geological history of our neighboring planets and moons in the solar system. 

From a practical standpoint, these depressions are also of interest - thanks to the protection they provide against radiation, meteorites and other hazards, they may serve as potential settlement sites for future missions to the Moon, Mars and to other planetary bodies.
