First Predicted Sighting of a Comet
On December 25, 1758, Halley’s Comet became the first comet to be seen after accurately predicting its passage.
Some of the first recorded sightings of Halley’s Comet date back to 240 BC. The comet was seen and recorded by the Chinese, Babylonians, and medieval Europeans, none of whom recognized it as a reappearance. Rather, they thought they were seeing different comets.
