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.

Famous quotes containing the word dust:
“Sometimes Death, puffing at the doore,
Blows all the dust about the floore:
But while he thinks to spoil the room, he sweeps.
Blest be the Architect, whose art
Could build so strong in a weak heart.”
—George Herbert (1593–1633)
“Custom calls me to’t.
What custom wills, in all things should we do’t,
The dust on antique time would lie unswept,
And mountainous error be too highly heaped
For truth to o’erpeer.”
—William Shakespeare (1564–1616)
“‘Tis no sinister nor awkward claim
Picked from the wormholes of long-vanished days,
Nor from the dust of old oblivion raked.”
—William Shakespeare (1564–1616)
