Non-periodic comets are comet
s that do not have confirmed observations at more than one perihelion passage, and thus generally have orbital periods of 200 years or more. They include single-apparition comets that pass through the Inner Solar System only once. They are on unstable near-parabolic orbits that will not return to the vicinity of the Sun
for hundreds, thousands, or even millions of years – if ever. (Some use the term non-periodic comet to refer exclusively to comets that will never return to the vicinity of the Sun.) Comets not expected to return to the inner Solar System include C/1980 E1

A comet is an icy small Solar System body that, when close enough to the Sun, displays a visible coma and sometimes also a tail. These phenomena are both due to the effects of solar radiation and the solar wind upon the nucleus of the comet...
