Constellation Crater

CONSTELLATION CRATER

THE CELESTIAL CUP & APOLLO'S CHALICE

STELLAR CARTOGRAPHY:

The Heavenly Chalice

Crater is a faint southern constellation representing a cup or chalice. Nestled between Leo and Hydra, it was cataloged by Ptolemy in the 2nd century and is classically associated with the mythical cup of the god Apollo.

BRIGHTEST STAR

DELTA CRATERIS

An orange giant star shining brightly as the luminary of the cup asterism.

CONSTELLATION AREA

282 SQ. DEG.

Ranked as the 53rd largest modern constellation by total sky coverage area.

Legacy of the Cup 📜

🍷

THE VESSEL | APOLLO

This constellation represents the goblet belonging to the god Apollo. In the myth of the Raven’s lie, it is the cup that remained empty while the bird feasted on ripening figs.

LABRADORITE STAR

Crater is home to R Crateris, a semi-regular variable star with a deep red hue. Astronomers often compare its color to the rich, dark wine that the cup was meant to hold.

THE SHAPE

Crater is remarkably easy to identify because its stars actually form the silhouette of a chalice or bowl, resting steadily on the coils of Hydra.

"Did you know? In ancient Mesopotamia, these stars were associated with the goddess Bau, the healer and protector of the city-state of Lagash!"

1. The Celestial Chalice

Crater is a faint yet distinctive southern constellation representing a cup or chalice, nestled along the back of Hydra.

2. Mythology & The Dishonest Crow

In classical lore, Crater is associated with the cup sent with a mendacious crow to fetch spring water for Apollo, ultimately cast into the heavens.

3. Alkes: The Orange Giant

The brightest star is Alkes (Alpha Crateris), an orange giant whose traditional Arabic name directly translates to "the cup".

4. Delta Crateris: The True Luminary

Though designated Alpha, Alkes is outshone by Delta Crateris, a luminous yellow-orange giant anchoring the western rim of the chalice.

5. Deep-Sky Galaxies within the Cup

Crater contains fascinating extragalactic targets, such as NGC 3511 and the interacting galaxy pair NGC 3885, visible through moderate telescopes.

6. Gravitational Lensing & Quasars

The constellation hosts RX J1131-1231, a remarkable gravitationally lensed quasar that allows astronomers to study supermassive black holes in the distant early universe.

7. Stargazing the Spring Chalice

Best observed high in the southern sky during spring evenings, Crater sits conveniently between Leo and Hydra for amateur astronomers.
