How to find Cancer
The faintest zodiac constellation — but home to the lovely naked-eye Beehive Cluster.
Al Tarf — the crab's modest brightest star (Beta Cancri).
Cancer is the dimmest of the zodiac constellations, a faint upside-down 'Y' tucked between bright Gemini and Leo. Its stars are easy to miss from the suburbs, but it hides a real treasure.
That treasure is the Beehive Cluster (M44), one of the nearest and brightest open star clusters.
The Beehive Cluster
Under a dark sky the Beehive (M44, also called Praesepe) appears as a soft glowing patch to the naked eye — ancient observers used it as a weather gauge, noting it vanished before storms as humidity rose. Binoculars resolve it into a swarm of dozens of stars, which is how it earned its name.
How to find it
- Find bright Pollux (Gemini) and Regulus (Leo); Cancer lies in the gap between them
- Look for a faint hazy patch in that gap — the Beehive Cluster
- A dark, transparent sky helps enormously; Cancer fades fast in light pollution
Deep-sky highlights
- Beehive Cluster (M44 / Praesepe) — a bright naked-eye open cluster
