1550 Tito

[2] This asteroid orbits the Sun at a distance of 1.7–3.3 AU once every 4 years and 1 month (1,482 days).

While this does not make it a slow rotator, it has a significantly longer period than the vast majority of minor planets, which typically spin every 2 to 20 hours around their axis.

Rotational lightcurves of Tito were obtained from photometric observations by Walter R. Cooney Jr. in January 2003, who derived a period of 54.2 hours (Δmag 0.23, U=2),[12] by Raymond Poncy in December 2006, who obtained a shorter, provisional period of 30 hours (Δmag 0.16, U=2),[11] and by David Higgins in December 2010, who derived a period of 54.53 hours (Δmag 0.40, U=2).

[13] According to the surveys carried out by the Spitzer Space Telescope, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Tito measures between 9.47 and 13.652 kilometers in diameter, and its surface has an albedo between 0.181 and 0.257.
