| has gloss | eng: A lost comet is a previously discovered comet that can no longer be observed, generally because there is not enough data to reliably calculate the comet's orbit and predict its location. Lost comets can be compared to lost asteroids, but they are quite different because of nongravitational forces that can affect comet orbits (one of which is emission of jets of gas from the comet nucleus). Some astronomers have specialized in this area, such as Brian G. Marsden who successfully predicted the 1992 return of the once-lost periodic comet Swift-Tuttle. Also unlike asteroids, some lost comets are not expected to return to the inner solar system, and even many non-lost comets are not be expected back for hundreds of years. |

| has gloss | slv: Izgubljeni komet je komet, ki so ga najprej odkrili in ga pozneje niso mogli več opazovati, ker je bilo premalo podatkov o njegovi tirnici. Izgubljene komete lahko primerjamo z izgubljenimi asteroidi. Vendar je med njimi velika razlika, ker na tirnice kometov lahko močno vplivajo tudi netežnostni vzroki. |
