उत्तर
Comets are the solar system bodies that are usually spherical in shape and develop tails when they come near the Sun. Comets become visible when they are close to the Sun and the Earth.
Comets can be categorized into two groups depending on how long it takes to complete one revolution around the sun. These are:
- Long Period Comets: These comets complete one revolution around the Sun in 200 and more years. The Great Comet of 1843 is one of the examples of this type.
- Short Period Comets: These comets complete one revolution around the Sun in years less than 200. One of the examples is Halley's Come, which takes 76 years to complete the revolution. It last appeared in 1985.
