History and cultural context

The mansion system developed as a way to organize the belt of sky traversed by the Moon and became embedded in calendrical, court and astrological practice. Ox belongs to the seven-mansion sequence of the Black Tortoise of the North; historical catalogues may differ in which faint stars are included.

How Ox maps the sky

A Chinese mansion combines a reference asterism with a strip of right ascension extending toward the celestial poles. It therefore cannot be reduced to either the similarly named IAU region or a single Western line figure.

Interesting facts about Ox

  • It is commonly located around stars spanning Capricornus and Sagittarius, but that comparison does not make it identical to a modern IAU constellation.
  • A Chinese mansion combines a reference asterism with a strip of right ascension extending toward the celestial poles.

How it fits the combined catalogue

The directory stores Ox as one canonical entry and uses badges for membership and overlap, rather than duplicating it under every official constellation it touches.

Research and cultural care

English mansion names are translations, not replacements for the Chinese terminology. Preserve the Chinese reading and avoid treating the Four Symbols as Western-style giant constellations.

A personal connection to the night sky

Name a star in Capricornus

Create a symbolic star registration with a certificate and sky coordinates, then use this guide to explore the surrounding sky. Cultural sky traditions do not always follow modern IAU boundaries, so availability is based on the corresponding astronomical region.

Star naming is a symbolic gift service. It does not change scientific names or designations maintained by the IAU.
