Cancer constellation from Johannes Hevelius' Prodromus astronomiae, Firmamentum Sobiescianum, sive Uranographia, 1687. Cancer is one of the constellations of the zodiac. It is one of the 48 constellations described by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations defined by the International Astronomical Union. Constellations directly bordering Cancer are Lynx, Gemini, Canis Minor, Hydra, Leo and Leo Minor. Cancer is the fourth astrological sign in the Zodiac, which is associated with the constellation Cancer. It spans the 90-120th degree of the zodiac, between 90 and 125.25 degree of celestial longitude, which the Sun transits this area on average between June 22 to July 22 each year. The Hevelius Firmamentum was the first star atlas to rival Bayer's Uranometria in accuracy, utility, innovation, and influence. Hevelius was perhaps the most active observational astronomer of the last half of the seventeenth century. His star atlas is notable for many reasons. It contains 56 large, double page engraved star maps. The star positions for the charts were derived from his own star catalog, based on his own observations, which was first published along with the atlas. It is unique among the Grand Atlases in choosing to depict the constellations as they would appear on a globe, that is, from the outside looking in, rather than from a geocentric point of view, as Bayer and most others adopted.
