[11] [12] [13] Alan Hale and Thomas Bopp discovered Comet Hale–Bopp separately on July 23, 1995, before it became visible to the naked eye.
Comet Hale–Bopp is expected to return to the inner Solar System.

After asserting that Comet Hale–Bopp was the sign that the group had been looking for, as well as the speculation that an unidentified flying object (UFO) may have been trailing the comet, Applewhite and his 38 followers prepared for ritual suicide, coinciding with the closest approach of the comet, so their souls could reach the Next Level ...

The small size of the nucleus (Halley's Comet is about 15 km (9.3 mi) across, while Comet Hale–Bopp was about 60 km (37 mi) across) implies that Hyakutake must have been very active to become as bright as it did. Most comets undergo outgassing from a small proportion of their surface, but most or all of Hyakutake's surface seemed to have been ...
