Centaur Scientific  

/ sĕn′tôr′ /

1. Any of a group of icy bodies similar to both asteroids and comets, orbiting the Sun in elliptical paths mostly in the region between Saturn and Neptune. Centaurs range in diameter from around 100 to 400 km (62 to 248 mi) and are believed to be Kuiper belt objects that have escaped into the vicinity of the gas-giant planets. Centaurs are considered to have unstable orbits, and gravitational encounters with the large outer planets could send them into the inner solar system or alternatively could eject them from the solar system into interstellar space. Chiron, the first such body to be classified as a Centaur, was discovered in 1977.

Etymology

Origin of centaur

First recorded in 1325–75; Middle English, Old English, from Latin centaurus, from Greek kéntauros

Explanation

Have you ever seen a centaur at the zoo? I doubt it! It's a mythological creature that's half-man, half- horse. Like elves, trolls, werewolves, zombies, and vampires, the centaur is a mythical creature, specifically a creature equal parts horse and man. This is a little like a mermaid, who is half-fish and half-woman. In case you were wondering, the top half is the man part. Even in the made-up world of mythology, the other way around just wouldn't work.
