Halley's Comet returns like clockwork

Halley's Comet, a celestial celebrity, graces our skies approximately every 76 years, making it one of the most predictable cosmic events. English astronomer Edmond Halley famously predicted its 1758 return, proving comets are not random omens but natural bodies orbiting the Sun. This icy, dusty nucleus, about 15 kilometers wide, forms a brilliant tail stretching millions of kilometers as it nears the Sun.
