Shooting stars – which are really just meteors – consist of bits of dust and rock falling into the Earth’s atmosphere and burning up. Meteors can move at incredible speeds and the faster and ...
A meteor or shooting star[8] is the visible passage of a meteoroid, comet, or asteroid entering 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.
27 kwi 2024 · A Shooting star happens when a meteoroid enters the Earth’s atmosphere at an extremely high speed producing friction or drag against the atmospheric air molecules. This friction creates heat, burning off chemicals within the meteor and causing the atmospheric gasses surrounding it to illuminate.
