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).
Comet. A smaller celestial body mainly composed of ice and dust. If a comet approaches the Sun it can generate a tail of gas and/or dust. An asteroid is a celestial body-composed of rock, metal or a mixture of both-that is orbiting the Sun. Most of them are in the asteroid belt between Mars and Jupiter.
