A comet is a small, icy object that orbits the sun and has a long tail of gas. Some comets can be seen from Earth every few years, while others pass by once in a person's lifetime. Comets are made of ice, dust, and tiny pieces of rock, but to people on Earth, they look like streaks or smudges across the night sky.
The Comet (Great Escape) (Redirected from Comet (Great Escape)) The Comet is a wooden roller coaster located at Great Escape in Queensbury, New York, in the United States. Originally known as the Crystal Beach Cyclone and rebuilt into the Crystal Beach Comet, the Comet was resurrected and re-opened by the Great Escape in 1994.
