Student A:When a meteoroid, comet, or asteroid enters Earth's atmosphere at a speed typically in excess of 20 km / s (72,000 km / h; 45,000 mph), aerodynamic heating of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a meteor or "shooting star".
