Dulcinea (minor planet designation: 571 Dulcinea) is an asteroid orbiting in the inner main belt.[3] It was named after Dulcinea, a character from Miguel de Cervantes' novel Don Quixote. This is classified as a stony S-type asteroid and it is the second largest member of the Erigone collisional family.[3]
