Meteors
Basics
-meteor is the visible path of a
meteoroid that enters the Earth’s
(or another body's) atmosphere,
commonly called a shooting star
or falling star.
-during the entry of a meteoroid
into the uppen atmosphere, an
ionization trail is created,
where the molecules in the upper
atmosphere are ionized by the
passage of the meteor. Such
ionization trails can last up to 45
minutes at a time
