Embark on a cosmic journey as we explore the crab-tivating world of Cancer constellation through these stellar fun facts!

1. Karkinos: Crab-turned-Constellation

Before zodiac signs were a thing, even crabs couldn’t resist the urge to pinch, poke, and meddle in a good ol’ mythical brawl: Cancer constellation was actually inspired by Karkinos, a giant crab in Greek mythology, who valiantly joined the clash between the Hydra and Herakles at Lerna. Its efforts didn't end well, but Karkinos earned a heavenly reward from the goddess Hera, who immortalized the crustacean as the constellation Cancer, forever shining down on wandering gazes from the night sky.

When you thought the end couldn't get any dimmer, enter Al Tarf, stage right: Known as Beta Cancri, the Cancer constellation features its own obscure star called Al Tarf, or "the end" in Arabic, which modestly marks the finale of one of our celestial crab's legs with a barely perceptible magnitude of 3.6.

If the stars had their very own apiary, it would undoubtedly be found in the constellation of Cancer: This celestial crab is home to two Messier objects, including M44, the Beehive Cluster, which is a buzzing assembly of stars that resemble a swarm of bees, and M67, another open star cluster.

4. Buzzworthy Beehive Cluster

Bee-have yourself, this celestial fact is quite the buzz: The Cancer constellation's Beehive Cluster, aka Praesepe or M44, is home to a whopping 1,000 stars, with red giants, white dwarfs, and the (inter)stellar neighborhood's first-ever detected planets orbiting Sun-like stars. Galileo himself scoped out this cosmic beehive, which is still creating quite the galactic buzz to this day.

Ladies and gentlemen, prepare to enter the buzzing beehive of the galaxy: the Beehive Cluster in the Cancer constellation!

Nestled into the bosom of Cancer, this nebulous mass has intrigued star-gazers so far back as Ptolemy, and even served as one of Galileo's first telescope targets. While these stellar swarms may not produce honey, they do share impressive origins and characteristics, the likes of which span from red giants and white dwarfs to mighty main sequence stars.

10. The Not-So-Diamond Planet

Here's a gem of a space tale for you: Once upon a time, astronomers thought they discovered a diamond-studded planet, dazzling in the night sky like Marilyn Monroe's best friend. But as with many glitzy fantasies, reality had other sparkling surprises in store: Turns out, 55 Cancri e, which resides in the Cancer constellation, may not be a "diamond world" after all.

13. Cancer Moon Sign: Emotional Detectives

Did you hear about the Cancers who moonlight as emotional detectives? They can sense when something's fishy in the emotional seas of their loved ones and relatives, but sometimes have trouble untangling the mysteries of their own feelings. Beware, though - their soft shells can be easily cracked by sketchy characters if they aren't careful: The Cancer moon sign is strongly connected to emotions and is particularly devoted to relationships, valuing the bonds of family and friends as sources of security. This sensitivity allows them to understand the deeper forces at play in daily interactions but must learn to discern their emotions from others to avoid being exploited.
