1846 Bengt, provisional designation 6553 P-L, is a dark asteroid from the inner regions of the asteroid belt, approximately 11 kilometers in diameter. Discovered by the Palomar–Leiden survey in 1960, it was named for Danish astronomer Bengt Strömgren.[2]

Discovery

Bengt was discovered on 24 September 1960, by Dutch astronomer couple

Cornelis van Houten in collaboration with Tom Gehrels, who took the photographic plates at Palomar Observatory in California.[4]

The

survey designation "P-L" stands for Palomar–Leiden, named after Palomar Observatory and Leiden Observatory, which collaborated on the fruitful Palomar–Leiden survey in the 1960s. Gehrels used Palomar's Samuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory where astrometry was carried out. The trio are credited with several thousand asteroid discoveries.[5]

The asteroid was first identified as 1951 CW1 at McDonald Observatory in 1951. The observation arc starts 3 years prior to its official discovery observation, with its first used identification 1957 YP made at Goethe Link Observatory in 1957.[4]

Orbit and classification

Bengt orbits the Sun in the inner main-belt at a distance of 2.0–2.7 AU once every 3 years and 7 months (1,306 days). Its orbit has an eccentricity of 0.14 and an inclination of 3° with respect to the ecliptic.[1]

Physical characteristics

Based on preliminary results by NASA's

lightcurve has been obtained.[6]
