Flash Facts: Halley's Comet


"Halley's Comet follows an orbit that enables it to make periodic visits in our skies every seventy-seven years or so. For more than three-quarters of this period, the comet is beyond the orbit of Neptune--where its speed slows down to about 1/2 mile a second. Its top speed as it flashes back toward the sun is 34 miles a second."
