Compound of 'eye' and 'pit' (from Old English 'pytt'). A descriptive anatomical term combining body part with a hollow space.
Your eye socket is literally called an 'orbit' because it orbits around a ball—the eye—just like planets orbit stars, showing how scientists borrowed celestial language for anatomy.
