9910 Vogelweide, provisional designation3181 T-2, is a stony Koronianasteroid and elongatedslow rotator from the outer regions of theasteroid belt, approximately 5 kilometers in diameter. It was discovered during the secondPalomar–Leiden trojan survey in 1973, and named after German medieval poetWalther von der Vogelweide.
Vogelweide was discovered on 30 September 1973, by the Dutch astronomersIngrid andCornelis van Houten, onphotographic plates taken by Dutch–American astronomerTom Gehrels atPalomar Observatory in California, United States.[8]
It was first observed as2115 T-1 at the discovering Palomar Observatory during the first Trojan survey in March 1971, extending the body'sobservation arc by more than 2 years prior to its official discovery observation.[8]
Thesurvey designation "T-2" stands for the secondPalomar–Leiden Trojan survey, named after the fruitful collaboration of the Palomar andLeiden Observatory in the 1960s and 1970s. Gehrels used Palomar'sSamuel Oschin telescope (also known as the 48-inch Schmidt Telescope), and shipped the photographic plates to Ingrid and Cornelis van Houten at Leiden Observatory whereastrometry was carried out. The trio are credited with the discovery of several thousand minor planets.[9]
Vogelweide is astony asteroid and member of theKoronis family, a group consisting of few hundred known bodies with nearlyecliptical orbits. It orbits the Sun in theouter main-belt at a distance of 2.8–3.0 AU once every 4 years and 10 months (1,778 days). Its orbit has aneccentricity of 0.03 and aninclination of 3° with respect to the ecliptic.[1]
In September 2012, two rotationallightcurves ofVogelweide were obtained from photometric observations at thePalomar Transient Factory in California. Lightcurve analysis gave arotation period of 117.438 and 118.905 hours with a brightness variation of 0.74 and 0.67magnitude in the R and S-band, respectively (U=2/2).[6]Vogelweide is aslow rotator, as most asteroids have spin rates of less than 20 hours. The relatively high brightness amplitude also indicates that the body has a non-spheroidal shape.
According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Vogelweide measures 5.991 kilometers in diameter and its surface has analbedo of 0.196.[4][5] TheCollaborative Asteroid Lightcurve Link assumes a standard albedo for stony Koronian asteroids of 0.24 and derives a diameter of 4.94 kilometers with anabsolute magnitude of 13.7.[3]
Thisminor planet was named forWalther von der Vogelweide (c. 1170 – c. 1230) a Germanminstrel of the 13th century and popular lyric poet ofMiddle High German.[2] The approved naming citation was published by theMinor Planet Center on 2 April 1999 (M.P.C. 34356).[10]
