11.1  METEORS, METEOROIDS, AND METEORITES

If you have spent even an hour looking at the night sky, you have probably seen a “shooting star,” a streak of light that appears in a fraction of a second and as quickly fades (fig. 11.1). Astronomers call this brief but lovely phenomenon a meteor.

 Why is the meteor’s track straight, whereas the star images are curved?

Figure 11.1

A time-exposure photograph captures a “shooting star” (meteor) streaking through the atmosphere. Stars make short trails in the photo over the duration of the photo as Earth rotates. Source: NASA
