the Little Horse

An ancient constellation possibly created by the Greek astronomer Hipparchus (160-120 B.C.). Equuleus can represent either the horse Celeris, the brother of Pegasus, or the horse created by the sea god Poseidon when his trident struck the earth during a contest with the goddess Athena. The constellation is small and dim making it difficult to see. It is located between Pegasus and Delphinus.
