This unique handbook for astronomers explains how meteoroid streams originate from the decay of meteoroids, comets and asteroids, and how they cause meteor showers on Earth. It contains the findings of recent space missions to comets and asteroids, the impact risks associated with meteors, and their possible role in the origin of life on Earth. The author identifies all known meteor showers, accompanied by fascinating details on the most important showers and their parent comets, and also predicts when exceptional meteor showers will occur over the next 50 years.
