When will Halley's Comet return?
When will we be seeing Halley's Comet again?
Halley's Comet's last appearance was in 1986, and its average period of revolution around the Sun is 76 years. But it turns out that the gravitational pull of the giant planets creates variations in that period of up to a few years (so the time between successive appearances isn't always exactly 76 years). Its next appearance should be in 2061.
