3353 Jarvis, provisional designation 1981 YC, is a carbonaceous Hungaria asteroid, slow rotator and suspected tumbler from the inner regions of the asteroid belt, approximately 10 kilometers in diameter.
It was discovered on 20 December 1981, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona, and named after Gregory Jarvis, who died in the Space Shuttle Challenger disaster.
Jarvis is a member of the Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun at a distance of 1.7–2.0 AU once every 2 years and 6 months (929 days). Its orbit has an eccentricity of 0.08 and an inclination of 22° with respect to the ecliptic. A first precovery was taken at the Siding Spring Observatory in 1980, extending the body's observation arc by more than one year prior to its official discovery at Anderson Mesa.
In July 2007, a rotational lightcurve of Jarvis was obtained from photometric observations by astronomer Brian Warner at his Palmer Divide Station, Colorado, in collaboration with Robert Stephens, Alan Harris and Petr Pravec. The re-examined lightcurve analysis gave a rotation period of 202 hours with a brightness amplitude of 0.50 in magnitude, superseding the original period solution of 40.8 hours (U=2+/2).
