3552 Don Quixote is a small Amor, Mars crossing, potentially hazardous asteroid. It has a highly inclined comet-like orbit,[1] and measures about 19 km in diameter.[1] Its rotation period is 7.7 hours.[1] It was discovered by Paul Wild in 1983,[1] and is named after the comic knight who is the eponymous hero of Cervantes' Spanish novel Don Quixote (1605).
Don Quixote is suspected to be an extinct comet.[4] Don Quixote is frequently perturbed by Jupiter.[5]
