Halley's Comet occupies a unique niche within the history of the world, acting as a celestial timepiece for the advancement of culture and technology, even well before we recognized it as a recurring phenomenon. Learn about the physical object, it's orbital mechanics, and the human events that have occurred during its cyclic appearances. We will not see this particular comet, but if a similar object is in the sky (they are fairly common), we will take a few minutes to actually observe it from the adjacent open area.
