BasicsBasics-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
