Dust, Interstellar
Particles of carbon, iron, and silicates coated with ice, making up about 1% of the mass of the interstellar medium. Each grain is about a micron in diameter. They are often associated with nebula and young stars. The average distance between dust grains is about 150 meters. A nuisance to starfaring vessels, because the impact at relativistic velocity tends to seriously erode the protective shielding, interstellar dust is highly prized by cloudharvesters and other hider phyles
