Dust ponds are a phenomenon where pockets of dust are seen in celestial bodies without a significant atmosphere, like asteroids, comets and some minor planets. These are smooth deposits of dust accumu

…experiments show that dusty surfaces tend to become smooth as a result of dust mobilization. This phenomenon is thought to explain the process of dust ponds in the asteroids 433 Eros and comet 67P/Churyumov–Gerasimenko. Strange glowing lights on the Moon are recorded from Earth for centuries. This phenomenon…
