That prospect turned me into a serious shopper for trip cancellation and interruption insurance (one policy usually covers both), a product I had always dismissed as a rip-off. Like other value-oriented consumers, I had seen no need to add several hundred dollarsâ worth of vacation insurance to the price of a vacation. Until that trip. Since then we have insured a couple of other trips, but never needed to make a claim. The only time we came close was in the wake of 9/11.
What is a Comet? A comet is a very small solar system body made mostly of ices mixed with smaller amounts of dust and rock. Most comets are no larger than a few kilometres across. The main body of the comet is called the nucleus, and it can contain water, methane, nitrogen and other ices. When a comet is heated by the Sun, its ices begin to sublimate (similar to the way dry ice âfizzesâ when you leave it in sunlight).
Kuiper Belt comets tend to have short orbital periods â usually around 200 years â and are therefore also known as short period comets. Some comets are thought to come from the Oort Cloud, a region almost a light year from the Sun.hey are primarily made of dust and ice. Considered to be remnants of the formation of our Solar System, most comets belong to the Kuiper Belt, a region beyond the orbit of the planet Neptune. Comet PanSTARRS was visible in early 2013.
