Target time：
Halley's Comet is the most famous short-period comet, returning roughly every 76 years and visible to the naked eye. It last returned in 1986 and will next reach perihelion on July 28, 2061. For those who witnessed the 1986 apparition, 2061 is a reunion; for younger generations, it will be their first chance to see it. This page counts down to that return.
