* Moon: The lunar maria, the dark, smooth plains on the Moon, are primarily composed of basalt.
* Mars: The Martian surface contains significant amounts of basalt, both in the form of volcanic flows and impact craters.
* Venus: The surface of Venus is largely composed of basalt, although the thick atmosphere makes it difficult to study in detail.
* Mercury: While less prominent than on other bodies, basalt is thought to be present on Mercury as well.
* Asteroids: Some asteroids, particularly those within the asteroid belt, are believed to have basaltic compositions.
While basalt is a common rock type in our solar system, it is not the only one. Other rock types, like granite and sedimentary rocks, are also found on other planets and moons, albeit in smaller amounts.
