Halley’s Comet, a short-period comet visible from Earth approximately every 76 years, has been documented throughout history, often coinciding with notable world events. Its appearances provide a unique timeline to explore historical contexts.

Each appearance of Halley’s Comet serves as a historical marker, allowing us to reflect on human progress, technological advancements, and the shifting geopolitical landscape.
