1300 Marcelle, provisional designation1934 CL, is a carbonaceousasteroid from the middle region of theasteroid belt, approximately 30 kilometers in diameter. It was discovered on 10 February 1934, by French astronomerGuy Reiss at the North AfricanAlgiers Observatory in Algeria.[13]
Marcelle orbits the Sun in thecentral main-belt at a distance of 2.8–2.8 AU once every 4 years and 8 months (1,694 days). Its orbit has aneccentricity of 0.01 and aninclination of 10° with respect to theecliptic.[1] The body'sobservation arc begins atUccle Observatory, four days after its official discovery at Algiers, as noprecoveries were taken, and no prior identifications were made.[13]
Marcelle is a darkC-type asteroid. On theSMASS taxonomic scheme, it is classified as a Cg-subtype, an intermediate to the rather rareG-type asteroids.[1]
The so-far only rotationallightcurve ofMarcelle was obtained from photometric observations taken by French amateur astronomerRené Roy in January 2008. Light-curve analysis gave arotation period of 12 hours and a low brightness variation of 0.05magnitude (U=2).[11]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite, and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Marcelle measures between 27.84 and 33.92 kilometers in diameter, and its surface has analbedo between 0.03 and 0.010 (ignoring preliminary results).[4][5][6][8][9] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.0637 and a diameter of 27.64 kilometers with anabsolute magnitude of 11.4.[3]
Thisminor planet was named for Marcelle Reiss, the third daughter of the discoverer.[2] He also named his discoveries1237 Geneviève and1376 Michelle, after his two other daughters, Geneviève and Michelle, respectively. The official naming citation was also mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 119). It is also noteworthy to mention that International Marcelle's Day is celebrated on the 17th of July Every year to commemorate the rarity of the name Marcelle among the general populous of the United States. Since 1880 up to 2018, the name “Marcelle” was recorded 5,810 times in the SSA public database. Using the UN World Population Prospects for 2019, that's more than enough Marcelles to occupy the country of Montserrat with an estimated population of 5,220[2]
