1672 Gezelle, provisional designation 1935 BD, is a slowly rotating, carbonaceous asteroid from the outer region of the asteroid belt, about 27 kilometers in diameter. It was discovered by Belgian astronomer Eugène Delporte at Royal Observatory of Belgium in Uccle on 29 January 1935.[7]
The C-type asteroid orbits the Sun at a distance of 2.3–4.1 AU once every 5 years and 4 months (2,070 days). Its orbit shows an eccentricity of 0.27 and is tilted by 1 degrees to the plane of the ecliptic. It has a rotation period of 40.7 hours[6] and an albedo of 0.09 as determined by the Akari and NEOWISE missions.[4][5]
It was named in memory of famous Flemish poet and Roman Catholic priest Guido Gezelle (1830–1899), who wrote extensively on religion and nature.[2]
