CCD photometry and model of MUSES-C target (25143) 1998 SF36
Résumé
We present photometric observations of the near-Earth asteroid (25143) 1998 SF36 from the 2001 apparition campaign, and we discuss the corresponding physical model. The asteroid's photometric behaviour is consistent with an S-type object, it has a retrograde pole at lambda =355o, begin {equation}ta=-84opartialm 5o, and its sidereal rotation period is P=12.132partialm 0.0005 hours. 1998 SF36 is elongated, with rough global dimension ratios a/b=2.0, b/c=1.3, but the elongation is not due to a bifurcated shape. The surface is not likely to contain major concavities. No significant albedo variegation was detected.
