| − | A '''meteor''' is a kind of stone that falls from the [[sky]]. The ancient [[Greek]]s believed that the stones were [[Zeus]]'s thunderbolts. A famous quote by [[Thomas Jefferson]]: | + | A '''meteor''' is a ''[[meteoroid]]'' (a small rocky object in space) that has entered the Earth's atmosphere. Friction causes it become burning in the atmosphere, causing the meteor to glow brightly. For this reason, a meteor is often referred to as a "shooting star" or "falling star". Most meteors are small and burn up in less than a second, but some very large ones glow brightly for many seconds and are called "fireballs" or "bolides." (See also [[Asteroid]]). |

| − | A major source of meteors lies between [[Mars]] and [[Jupiter]], it is an enormous cluster of meteors, also known as an [[asteroid belt]]. Other meteor belts and clouds exist. It is the [[Earth]]'s passing through these belt and clouds that causes periodic [[meteor shower]]s such as the [[Perseiids]], [[Geminids]], and [[Taurids]]. | + | A major source of meteors lies between [[Mars]] and [[Jupiter]], an enormous cluster of meteoroids also known as the [[asteroid belt]].

| − | Strictly speaking, "meteors" are stones that are falling through the sky (aka "fireballs"). When they hit the ground, they become known as "meteorite." However, not many people bother to make this technical distinction. Even some [[textbook]]s get it wrong.
