Didymos

Didymos is a small asteroid.^[1] It is orbited by an even smaller moon, Dimorphos. NASA scientists launched a space probe called "Double Asteroid Redirection Test" (DART), to study the system, and then collide with Dimorphos.

The two asteroids are not a threat to Earth, but because they do pass relatively close to Earth, they were chosen as the target for NASA’s Double Asteroid Redirection Test (DART) mission – the agency's first mission to test planetary defense technology. This technology could one day be used to deflect hazardous asteroids on a collision course with Earth.
