Shooting
stars are tiny meteors that glow white hot when they hurtle from out of space
into the earth’s atmosphere.
If
you look up at the sky long enough on a dark, clear night, you may see the
fiery streak of a “shooting star” flash across the sky.

The
“shooting stars” that streaks across the sky are bits of rock and metal called
meteors. Many billions of meteors zip around through space.
Many
of them come so close that they are captured by earth’s gravity, and are pulled
toward earth. As the speeding meteors hurtle into the earth’s atmosphere,
friction with the air causes them to glow white hot. Then we see them as
blazing trails of lights.
Meteors
rarely blaze for more than a few seconds. Most of those we see were
originally no bigger than a grain of rice. They usually burn up before
they reach the ground.
Meteors
that survive their fall and land on earth are called meteorites.-Dick Rogers
