本文介绍了2001年观测活动中对近地小行星（25143）1998 SF36的光度观测，并讨论了相应的物理模型。这颗小行星的光度行为与s型天体一致，它在$\lambda=355^\circ,\ \ \beta=-84^\circ\pm 5^\circ$有一个逆行的极点，它的恒星自转周期为$P=12.132\pm 0.0005$小时。1998 SF36被拉长，具有粗略的整体尺寸比$a/b=2.0$, $b/c=1.3$，但拉长不是由于分叉的形状。地表不太可能有大的凹坑。未检测到明显的反照率变化。
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 $\lambda=355^\circ,\ \ \beta=-84^\circ\pm 5^\circ$, and its sidereal rotation period is $P=12.132\pm 0.0005$ 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.
