15% of asteroids near Earth actually have small moons orbiting them. Images taken by NASA's DART spacecraft have been examined and found that such asteroids are transferring material between each other. In a gentle collisions they are actively exchanging rocks and dust. The cause is sunlight which makes them spin faster and enabling material to fly off. Some of this material forms moons.astrobiology.com/2026/03/new-nā¦
