Dust
- Debris disk consists of planetesimals along with fine dust and small amounts of gas generated through their collisions and evaporation. The original gas and small dust particles have been dispersed or accumulated into planets.
- Zodiacal cloud or interplanetary dust is the material in the Solar System created by collisions of asteroids and evaporation of comet seen to observers on Earth as a band of scattered light along the ecliptic before sunrise or after sunset.
- Exozodiacal dust is dust around another star than the Sun in a location analogous to that of the Zodiacal Light in our own Solar System.
