| Description |
English: Atlas Image mosaic of the largest asteroid in the Solar System, 1 Ceres, seen against the Virgo Cluster of galaxies on 2000 Apr 6 UT during routine operations of the northern 2MASS facility on Mt. Hopkins, AZ. The asteroid is seen about 13.7´ west and 25.6´ south of the large spiral galaxy M100. Ceres is quite bright in this image, with Ks=5.50, J-H=0.37, and H-Ks=0.09 mag. Purplish known persistence artifacts trail (in decreasing brightness) due north of the asteroid. The fainter reddish "star" immediately east of due north, and the fainter whitish "star" immediately west of due south of the asteroid are known 2MASS "filter glint" artifacts. Sykes et al. (2000, Icarus, 146, 161) have studied asteroids detected by 2MASS, and the colors for Ceres are consistent with those for other C-type (carbonaceous chondritic) asteroids. The 2MASS Second Incremental Data Release Point Source Catalog contains 3804 associations with known asteroids. (Field size 20´ × 31´. Image size 1.7 Mb!)
Italiano: Immagine del più grande asteroide della fascia principale del Sistema solare, Cerere, visto in prossimità dell'ammasso di galassie della Vergine il 6 aprile 2000 UT durante operazioni di routine nell'ambito del 2MASS condotto dal telescopio settentrionale dell'osservatorio di Mt. Hopkins, in Arizona. L'asteroide si presenta a 13,7' Ovest e 25,6' Sud della grande galassia a spirale M100. Cerere (in badsso a destra) è abbastanza luminoso in questa immagine, raggiungendo una magnitudine di Ks=5,50, J-H=0,37, and H-Ks=0,09. Le macchie fioche e rossastre a nord di Cerere e quelle biancastra ad ovest, sono artefatti introdotti dallo strumento. |
