内容简介

The earth is bombarded both day and night by meteoroids and meteorites. These wayward bodies--small fragments derived from aging comets and the collisions between asteroids--are observed in the Earth's upper atmosphere as meteors and brilliant fireballs. Written with the amateur astronomer in mind, this book includes step-by-step guidance on visual observation and analyzing data, practical projects that demonstrate how the observer can gather scientifically useful data, and instructions on how to identify and photograph meteor trails.
