Comet Halley is a fine example of a short-period comet, taking about 76 years to make one orbit around the Sun. At its closest point (perihelion), the comet is only 88 million kilometers from the Sun (about 60% of the Earth's distance from our star.) At its most distant point (aphelion), Halley is 5.2 billion...

In 1986, the last time Comet Halley swung past the Sun, solar heating evaporated about 6 meters of dust-laden ice from the comet's nucleus. That's typical, say researchers. The comet has been visiting the inner solar system every 76 years for millennia, shedding dust each time.
