Cnc - Cancer the Crab

A faint constellation between Gemini and Leo.

Procyon, the brightest star of Canis Minor, serves as the vertex of the Winter Hexagon lying between Gemini and Sirius.

Look for the two bright stars, Castor and Pollux, which form one vertex of the Winter Hexagon. Castor is closer to Capella, in Auriga on the north; and Pollus is closer to Procyon, in Canis Minor on the south. Cancer and Leo lie to the east.

The Geminids meteor shower occurs around October 19.

Hydra the Water Snake is the largest and longest of the constellations, stretching from Cancer to Libra. Several constellations and asterisms ride on its back; from head to tail they are Sextans the Sextant, Crater the Cup, Corvus the Crow, and Noctua the Owl.

East of the Gemini twins lies Leo the Lion.

Find the bowl of the Big Dipper. A line running through the two stars of the bowl of the Big Dipper on the side nearest the handle points almost directly to two other notable stars. Follow them below the bowl of the Dipper to Regulus.

Leo’s mane looks like a backward question mark, or sickle. Regulus, the "dot" at the bottom of the mark, lies nearly on the ecliptic.

His flank is a triangle of stars farther east.

Lying between Ursa Major and Gemini, the Lynx is a row of very dim stars silhouetting its crouched outline. From antiquity the lynx was renowned for its keen night vision. Hevelius created this constellation in 1690, noting that one needs the eyes of a lynx to see it.
