Syuichi Nakano

Syuichi Nakano is a Japanese astronomer. He specializes in the study of comets, in particular calculating their orbits and making predictions about when periodic comets will return for another perihelion approach. It is considerably more difficult to predict the orbits of comets than of other types of Solar System objects, since their orbits are susceptible not only to perturbations from the planets but also to non-gravitational forces due to the release of gaseous material in the form of a comet's coma and tail.
