Comet West (c/1975 V1) is expected back in about 558,000 years. (don't wait up for it) :) If at all, during it's last approach it was observed to have split into four segments.

Comet Swift-Tuttle orbits the Sun once every 133 years, so it won't be visible from Earth until it returns in the year 2126. It is the source of the Perseid meteor shower which occurs annually in August when Earth passes through the debris left by the comet.
Next appear in mid-2061
Aside from the regular short-period and dim comets, not noticed by the average person (such as Comet Encke or Comet Tuttle 1) the next comet we can be reasonably sure of seeing is good old Comet Halley, next scheduled to appear in July of 2061. But there will almost certainly be at least one or two large, bright comets visible on earth before then - we just don't know when they will be. Comets, even large, spectacular comets, are frequently just discovered about 4-9 months before they become a great display in the night sky. None meeting the criteria are in sight right now - but stay tuned.
Halley's Comet appears approximately every 75-76 years. Its last appearance was in 1986, so the next predicted return would be around 2061.
Halley's comet was most recently seen in the 20th century in 1986. Its next predicted perihelion is in 2061.
Halley's Comet is projected to return to the inner solar system in 2061. It follows a roughly 76-year orbit around the Sun, with its last appearance being in 1986.
