Abstract:	摘要： Low-inclination near-earth asteroid (NEA) (297274) 1996 SK, which is also classified as a potentially hazardous asteroid, has a highly eccentric orbit. It was studied by multi-wavelength photometry within the framework of an NEA color survey at Lulin Observatory. Here, we report the finding of large color variation across the surface of (297274) 1996 SK within one asteroidal rotation period of 4.656 + or - 0.122 hours and classify it as an S-type asteroid according to its average colors of B - V = 0.767 + or - 0.033, V - R = 0.482 + or - 0.021, V - I = 0.801 + or - 0.025 and the corresponding relative reflectance spectrum. These results might be indicative of differential space weathering or compositional inhomogeneity in the surface materials. 出版日期： 2014-03 出處： Research in astronomy and astrophysics, 2014-03, Vol.14 (3), p.311-318 資源來源： Institute of Physics Journals 識別號： ISSN: 1674-4527 識別號： DOI: 10.1088/1674-4527/14/3/005
