Why does Mar's two moons look like asteroids?

Mars' two moons, Phobos and Deimos, resemble asteroids because they are thought to be captured objects from the asteroid belt rather than being formed from the same material as Mars. Their irregular shapes and small sizes are typical of many asteroids, and their composition is similar to that of carbonaceous asteroids. This suggests that they may have originated from the same primordial material that formed the early solar system, leading to their asteroid-like characteristics.
