Planisphere: A map of the celestial sphere or a portion of it, projected onto a flat surface, often featuring a rotating disk to show the visible stars at any given time.

Celestial: Relating to the sky or the heavens; in this context, the mapping of stars and planets.

Asterisms: Small groups of stars that form a pattern but are not necessarily part of the 88 modern constellations; Chinese astronomy is based on a vast system of these smaller patterns.
