Technically, a meteor (from the Greek meteoron, meaning "phenomenon in the sky") is merely the streak of light we see trailing a meteoroid. A meteoroid is any interplanetary object bigger than a speck of dust and smaller than an asteroid that has entered Earth's atmosphere and is burning up due to friction forces. Once it hits Earth, a meteoroid suffers an identity crisis and becomes a meteorite. Chase that, Superman: Perseid meteoroids enter the atmosphere (become meteors) at approximately 130,000 miles per hour. Called the Perseid Meteor shower.... Each day, up to 4 billion meteors fall into Earth's atmosphere. Some make it to the surface of Earth and are classified meteorites, some just burn completely away. Meteors are known to scientists as Near Earth Objects. One way of changing the direction of a Near Earth Object is to explode a nuclear device in its vicinity. The resulting radiation pulse would vaporize the object's surface; as the vapor streamed away, it would deliver a thrust that could throw the body off course. This push is known as an X-ray slap. Alright! Simple quiz: What is a meteroid? What is a meteor? Are they the same? NO! A meteoroid is a piece of rock orbiting the Earth that has broken off of an asteroid or comet. A meteor is a piece of rock that used to be a meteoroid and now has entered the Earth's atmosphere to BURN up or land on the Earth. Rocks from space that land on earth are meteorites. Got it? Tomorrow we look at meteorite damage!
