Space weathering

Space weathering is when a space object (like a planet, asteroid, or moon) is changed by the conditions in space. The sun is one of the biggest causes of space weathering. The sun's energy can damage the surfaces of objects, creating a layer that makes them darker and rougher. Space weathering can also be caused by radiation from other stars, asteroids, and comets, as well as tiny specks of dust that hit the objects at high speeds. Overall, space weathering is when the surface of an object in space is changed by things like the sun's energy and radiation.
