A shape is not always a constellation
Learn the formal names behind familiar patterns in the sky.
Use the official set
The International Astronomical Union recognizes 88 constellations. Everyday names for star patterns do not always identify one of those official constellations.
Our astronomy prompts use official constellation names. A familiar smaller pattern can belong inside a constellation without being a separate member of the official set.
Connect names to a map
Use a sky chart to connect neighbouring names. The goal is a reliable route through the set, not a belief that a flat printed chart reproduces every observing condition.
Visibility depends on location and time. A general label such as northern or southern should not be read as a promise that a constellation is visible from every place in that half of Earth at every hour.
Handle Latin and English
Formal constellation names are Latin forms; an English interpretation is a memory cue. Only reviewed equivalents are accepted by the game.
Do not confuse a constellation with an astrological sign when a prompt specifies astronomical objects. The familiar labels overlap in places, but the concepts and boundaries differ.
