Cosmic dust demystified

The solar system is a dusty environment, with trillions of cosmic dust particles left behind by comets and asteroids that orbit the sun. All this dust forms a relatively dense cloud through which the Earth travels, sweeping up the interplanetary dust particles very effectively.
