what year will halley's comet will come back? last time was in 1986

OpenStudy (anonymous):

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. Which is the exactly year my local church will open our time capsule :D An which I'll be exactly 60 years old lol
