Formed by Hevelius, in 1687, from a portion of Ursa Major. As early as 1533 maps of Boötes, the Herdsman, showed him holding leashes for two or three dogs; but the position of the dogs didn't correspond to any particular stars, and varied from one atlas to another. So Hevelius is the first to have placed them in their present position.

     Stars which have common names often have multiple names, so the common names shown (if any) cannot be considered authoritative. Right ascension and declination are given in 2000.0 coordinates.
