An observer of objects in the Solar System, Giovanni Schiaparelli worked on binary stars, discovered the large main-belt asteroid 69 Hesperia on 29 April 1861, and demonstrated that the meteor showers were associated with comets.
Giovanni Schiaparelli proved, for example, that the orbit of the Leonid meteor shower coincided with that of the comet Tempel-Tuttle.
Giovanni Schiaparelli was a keen observer of the inner planets Mercury and Venus.
Giovanni Schiaparelli made several drawings and determined their rotation periods.
Giovanni Schiaparelli was a scholar of the history of classical astronomy.
Giovanni Schiaparelli was the first to realize that the concentric spheres of Eudoxus of Cnidus and Callippus, unlike those used by many astronomers of later times, were not to be taken as material objects, but only as part of an algorithm similar to the modern Fourier series.
Giovanni Schiaparelli was elected to the American Philosophical Society in 1901.
