In September 2022, a small spacecraft called DART hit the surface of a tiny asteroid moonlet called Dimorphos.

Comets are small objects in our solar system made of ice and dust. As they get closer to the Sun in their orbits, the ices turn into gas and give off a glow that can be seen in telescopes. With luck, that glow brightens to the point where a comet can be seen with the unaided eye. Some, like Halley's Comet, return on a regular schedule. Others are m…
