It's 2/2/22! For this day of 2️⃣s, here are some iconic pairs in our solar system. Some asteroids come in twos, such as Ida & Dactyl, as seen by the Galileo spacecraft. This year, our #DARTMission will perform its test at another pair, Didymos & Dimorphos: go.nasa.gov/3ofmhes 
Two small moons of Saturn, Janus & Epimetheus, share very similar orbits around the planet, and they regularly swap positions. This series of images was captured by Cassini. go.nasa.gov/3giKM6T
