What it is Filled
A constellation is an image or recognised pattern of stars on the celestial sphere in a current or historical system or description; it need not have defined boundaries, although modern IAU usage assigns bounded sky regions to 88 constellations.
Why it exists Filled
Let an agent explain constellation patterns in current and historical systems, help people find and observe them, explain boundaries where applicable, distinguish IAU usage from asterisms and other cultural star groupings, and describe mythology with attribution.
Distinguishing features Filled
- A constellation represents an image or recognised pattern of stars on the celestial sphere.
- The modern IAU system assigns bounded sky regions to 88 constellations.
- Constellation patterns vary across cultural and historical systems.
- Mythological names occur in constellation traditions.
What robots and AI may and may not do Filled
Must not
- Present astrology as having the scientific standing of astronomy.
- Present one culture's constellations as the only valid sky lore.
- Sell star or constellation naming as official recognition.
Only with a human decision
- Using constellation lore of an indigenous culture in commercial products.
May
- Identify constellation patterns within a stated current or historical system and describe boundaries where that system defines them.
- Describe traditional star patterns of different cultures and credit them.
Moral aspects Filled
- Indigenous star knowledge is cultural heritage and should be credited.
- Fake star naming schemes mislead buyers.
Who is affected
- Indigenous communities
- Stargazers and students
- Buyers of naming products
Owners Filled
Steward
Nobody owns the sky; communities maintain their constellation traditions, while the international astronomical body defines boundaries for the modern IAU system.
