7346 Boulanger  7346 Boulanger, provisional designation , is a Koronian asteroid from the outer regions of the asteroid belt, approximately in diameter. It was discovered on 20 February 1993, by Belgian astronomer Eric Elst at the CERGA Observatory in Caussols, southeastern France. It was named after French Enlightenment philosopher Nicolas Boulanger. "Boulanger" is a member of the Koronis family (), a very large outer asteroid family with nearly co-planar ecliptical orbits. It orbits the Sun in the outer main-belt at a distance of 2.6–3.1 AU once every 4 years and 11 months (1,781 days; semi-major axis of 2.88 AU). Its orbit has an eccentricity of 0.08 and an inclination of 3° with respect to the ecliptic. The body's observation arc begins with a precovery taken at Palomar Observatory in April 1955, nearly 38 years prior to its official discovery observation at Caussols. In the SDSS-based taxonomy, "Boulanger" is a common, stony S-type asteroid, which agrees with the overall spectral type for Koronian asteroids. It has an absolute magnitude of 12.8. As of 2018, no rotational lightcurve of "Boulanger" has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown. According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, "Boulanger" measures 7.378 kilometers in diameter and its surface has an albedo of 0.270. This minor planet was named after Enlightenment philosopher and geologist Nicolas Antoine Boulanger (1722–1759). The official naming citation was published by the Minor Planet Center on 24 June 2002 ().
