History

Historical Context

Comet Hale-Bopp, discovered in July 1995 by Alan Hale and Thomas Bopp, became one of the brightest comets in history, visible for 18 months. Its nucleus, about 40 kilometers wide, last appeared approximately 4,000 years ago. The excitement surrounding Hale-Bopp parallels the anticipation for comet 3I/ATLAS, which travels at 130,000 miles per hour, highlighting ongoing interest in celestial phenomena.
