If a comet is periodic, it means that it comes back regularly.
It is called a Coma.
Most comets travel around the Sun in elliptical paths. The time it takes a comet to make a complete orbit is called its period. Some comets have short periods of less than seven years. Others travel in such huge orbits that they pass near the Sun only once in thousands or even millions of years. As of 1995, 878 comets have been catalogued and their orbits at least roughly calculated. Of these 184 are periodic comets (orbital periods less than 200 years); some of the remainder are no doubt periodic as well, but their orbits have not been determined with sufficient accuracy to tell for sure. No comets seem to have approached the Sun from beyond the limits of the solar system. Therefore, all comets seen by astronomers are considered part of the solar system.
Comets are Comets and Asteroids are Asteroids
what ploh does mean
comets can be found at any time in the west two hours after sun set when the sky is dark or in the east a few hours befor sun rise comets can be found at any time it takes a lot of dedecation and time if you know the sky well ul know when uv found a comet you could be lucky one nite
See related link for a list of periodic and non periodic comets.
Comets. Periodic comets have highly eccentric elliptical orbits, with eccentricities.
Short period comets have a period of less than 200 years Long period comets have a period of more than 200 years.
It is called a Coma.
There are no known periodic comets with periods near 10K years.

Ai is not an element on the periodic table
If you mean all our planets and comets, it's called the Sun. It is called "The Solar System".
Ni is the symbol for Nickel in the Periodic Table.
