Comet opened in 1946. In 1964, Comet received 6,650 individual 10-watt chaser lights. In 1994, Comet received 2 new trains named "Mork's Comet" and "
Halley's Comet". The names were removed when the comets got new trains in 2024. One of the old trains is currently used as seating at the
Hershey Museum, and the other was donated to the National Roller Coaster Museum and Archives. Comet was re-tracked during the off-season in 2006, and new seat belts were added two years later. Comet was repainted the same color white, and the station was redone, during the 2012 off-season. Two years later, the lift hill was rehabilitated and straightened, removing the well known "kink" that was in the lift hill. At the 2023
IAAPA Expo, it was announced that Comet would receive new PTC trains for the 2024 season. ==Ride experience==
