Detailed Description

Abstract base for any celestial object that can be tracked from an observer location.

Subclasses represent concrete target kinds: fixed sky directions, catalog stars, solar-system bodies, and (in the future) satellites. All must implement name(), altitude_at(), and azimuth_at(); the search helpers also need overrides.
