Space contains tons of dust. When dust particles approach Earth, they can be captured by gravity and enter the atmosphere at very high speeds.
Particles with diameters larger than about 2 millimeters undergo very rapid heating through collisions in our atmosphere. As they heat up, they can produce a short-lived trail of light known as “shooting star.” Most dust particles entering the atmosphere are estimated to be much smaller than this and don’t provide a visible trail.
