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...

s starting in 1985 (since comets are subject to non-gravitational forces due to outgassing and solar wind, it is often a challenge to predict their exact position and rediscover them each time they make a new perihelion approach). He confirmed the discovery of the well known Comet Shoemaker-Levy 9
Comet Shoemaker-Levy 9
Comet Shoemaker–Levy 9 was a comet that broke apart and collided with Jupiter in July 1994, providing the first direct observation of an extraterrestrial collision of solar system objects. This generated a large amount of coverage in the popular media, and the comet was closely observed by...

 in July 1994. He has also discovered the periodic comets 202P/Scotti, 244P/Scotti, P/2003 L1 (Scotti), P/2010 C1 (Scotti), P/2010 H4 (Scotti), P/2010 H5 (Scotti), P/2011 A2 (Scotti), the later seven are not yet numbered as they have only been seen at one perihelion passage. He has also discovered non-periodic comets C/2010 E5 (Scotti) and C/2010 F3 (Scotti).

Scotti's research interests include the origin of comets, the dynamical evolution of comets and asteroids, the Near-Earth Asteroids, and the outer solar system.

Scotti is also an avid space enthusiast and is interested in the history of space exploration and particularly of the Apollo Program. He has contributed to the Apollo Lunar Surface Journal, which details the Apollo lunar explorations. He is also a space artist and photographer.
