16879 Campai, provisional designation 1998 BH10, is carbonaceous asteroid and very slow rotator from the outer region of the asteroid belt, about 11 kilometers in diameter. It was discovered on 24 January 1998, by Italian astronomers Andrea Boattini and Maura Tombelli at the Pistoia Mountains Astronomical Observatory in San Marcello Pistoiese, Tuscany, central Italy.[6]
The dark C-type asteroid orbits the Sun at a distance of 2.7–2.8 AU once every 4 years and 7 months (1,673 days). Its orbit has a low eccentricity of 0.03 and an inclination of 7° with respect to the ecliptic.[1] Based on an absolute magnitude of 13.6 and an assumed albedo of 0.057, the Collaborative Asteroid Lightcurve Link (CALL) calculates a diameter of 10.5 kilometers.[3]
In 2010, a photometric light-curve analysis at the U.S. Palomar Transient Factory, California, rendered a rotation period of 314.2468±4.9149 hours with a brightness amplitude of 0.68 in magnitude (U=2).[4] While the result is based on less than full coverage, and may be refined by future observations, the body is one of the slowest rotating asteroids known to exist.
The minor planet is named for amateur astronomer Paolo Campai (b. 1957) from Florence, who is specialized in teaching and astrophotography. Both discoverers made his acquaintance near Florence on a night in 1985, while observing α Phoenicis and comet 1P/Halley.[2]
