摘要
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 = 355degrees; beta = - 84degrees +/- 5 degrees, and its sidereal rotation period is P = 12.132 +/- 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.
