Syuichi Nakano (中野 主一,Nakano Shuichi; born September 11, 1947) is a Japaneseastronomer. He specializes in the study ofcomets, in particular calculating their orbits and making predictions about when periodic comets will return for anotherperihelion approach. It is considerably more difficult to predict the orbits of comets than of other types ofSolar System objects, since their orbits are susceptible not only toperturbations from theplanets but also to non-gravitational forces due to the release of gaseous material in the form of a comet'scoma and tail.

He is affiliated with the Computing & Minor Planet Sections (Center for Astrodynamics) of theOriental Astronomical Association inSumoto,Japan.

He publishes theNakano Notes on comet observations and ephemerides.

In 2001 he won theAmateur Achievement Award of theAstronomical Society of the Pacific. Theasteroid3431 Nakano is named after him, and asteroid3983 Sakiko is named after his sister.

1026 Ingrid was reidentified in 1986 by Syuichi Nakano, ending its time as alost asteroid.^[1]3568 ASCII is another long-lost asteroid whose recovery was made by Nakano.
