List of comets
This is a list of some comets in the solar system.
Periodic comets visit us again and again. Non-periodic comets visit us only once. On this list there is a "P" in front of the periodic comets. In front of non-periodic comets there is a "C". There is sometimes a number in front of the "P": it shows the number of times people saw the periodic comet visiting us.

Periodic comets
changePeriodic comets have a special place in astronomy, because their orbits are often the same. We know when they will visit us, and we can plan to watch them, and send space probes to look at them.
On August 24, 1994, the International Astronomical Union (IAU) standardized the way they name this type of comet. This system tells us which comet is which. The IAU chose the letter P for periodic comets and D for periodic comets that were lost or which broke into pieces. Other letters are C for non-periodic comets, and X for comets where we do not know their orbits. It uses A for objects people say are asteroids. Each name starts with a number, so two comets have the same name.
