斯隆数字巡天（SDSS）和宽视场红外巡天探测器（WISE）提供了大约10万颗小行星的表面组成信息。由此产生的可见颜色和光谱使我们能够将它们分为几个主要类别，这是对少数现有光谱所显示的多样性的简化视图。我们在VISTA-VHS观测中进行了一次偶然的搜索，使用开发的管道来检索和处理对应于太阳系天体（SSo）的数据。VISTA巡天观测到的小行星的颜色和星等被汇编成三个目录，可在线获得：探测目录（MOVIS-D），星等目录（MOVIS-M）和颜色目录（MOVIS-C）。它们是使用调查的第三次数据发布（VISTA VHS-DR 3）构建的。共探测到39，947个天体，包括52个近地小行星、325个火星十字星、515个匈牙利小行星、38，428个主带小行星、146个Cybele小行星、147个Hilda小行星、270个特洛伊小行星、13个彗星、12个柯伊伯带天体和海王星及其四颗卫星。在已知光谱特性的小行星上发现的颜色揭示了与不同矿物相对应的明确的模式。MOVIS-C数据在颜色-颜色图中的分布显示了不同分类类型的聚类。所有使用（Y-J）颜色的图都比目前使用的（J-H）和（H-Ks）图更有效地分离光谱类别：即使对于大的颜色误差（<0.1），图（Y-J）vs（Y-Ks）和（Y-J）vs（J-Ks）也提供了S-复合体和C-复合体之间的分离。端员A、D、R和V型占据明确的区域。
The Sloan Digital Sky Survey (SDSS) and Wide-field Infrared Survey Explorer (WISE) provide information about the surface composition of about 100,000 minor planets. The resulting visible colors and albedos enabled us to group them in several major classes, which are a simplified view of the diversity shown by the few existing spectra. We performed a serendipitous search in VISTA-VHS observations using a pipeline developed to retrieve and process the data that corresponds to solar system objects (SSo). The colors and the magnitudes of the minor planets observed by the VISTA survey are compiled into three catalogs that are available online: the detections catalog (MOVIS-D), the magnitudes catalog (MOVIS-M), and the colors catalog (MOVIS-C). They were built using the third data release of the survey (VISTA VHS-DR3). A total of 39,947 objects were detected, including 52 NEAs, 325 Mars Crossers, 515 Hungaria asteroids, 38,428 main-belt asteroids, 146 Cybele asteroids, 147 Hilda asteroids, 270 Trojans, 13 comets, 12 Kuiper Belt objects and Neptune with its four satellites. The colors found for asteroids with known spectral properties reveal well-defined patterns corresponding to different mineralogies. The distributions of MOVIS-C data in color-color plots shows clusters identified with different taxonomic types. All the diagrams that use (Y-J) color separate the spectral classes more effectively than the (J-H) and (H-Ks) plots used until now: even for large color errors (<0.1), the plots (Y-J) vs (Y-Ks) and (Y-J) vs (J-Ks) provide the separation between S-complex and C-complex. The end members A, D, R, and V-types occupy well-defined regions.
