Why is halleys comet the only visible to the naked eye?

Halley's Comet is one of the few comets that can be seen with the naked eye because it has a relatively short orbital period of about 76 years, bringing it close to Earth more frequently than most comets. Its brightness is enhanced by its large nucleus and the gases and dust it releases when it approaches the Sun, creating a bright coma and tail. Additionally, its predictable return allows for public awareness and observation during its appearances, making it a well-known celestial event.
