Comets, Centaurs, and TNOs
Some of the smallest members of our solar system have been known since antiquity. Comets were very mysterious objects to the ancient world. They had an unusual “hairy” appearance.[1] Unlike planets, comets seemed to follow no predictable path. They appeared at an unpredictable time, brightened and moved in unpredictable ways, and faded into oblivion. Many cultures considered comets to be omens.
