Non-periodic comets are defined for these purposes as comets that have an orbital period of 200 years or more, including single-apparition comets that pass through the inner solar system only once. They are usually on near-parabolic orbits that will not return to the vicinity of the Sun for thousands of years, if ever. (Note that some use the term "non-periodic comet" to refer to exclusively to comets that will never return to the vicinity of the Sun.)

The official names of non-periodic comets begin with a "C"; comets that have been lost or disappeared have names that begin with a "D". An example of the latter is Comet Lexell (D/1770 L1), which is known to have been probably ejected from the Solar system by Jupiter.

The following is a partial list of non-periodic comets that have appeared in the solar system:
