本文介绍MUSES-C任务使命靶（25143）1998 SF 36的热观测结果.使用ESO 3.6 m望远镜和TIMMI 2测量了N波段（11.9 μ m）的中红外辐射。在标准热模型下，结合N波段的热通量和光学时间分辨绝对星等，得到的直径和几何半径分别为0.35（± 0.03）km和0.23（+0.07，-0.05）。虽然这些值是依赖于模型，我们的结论是，这阿波罗级小行星是小尺寸和它的反射光谱分类为S-型小行星是一致的。
We present thermal observations of MUSES-C mission target, (25143) 1998 SF 36 . The mid-IR radiation in the N -band (11.9 μ m) was measured using the ESO 3.6 m telescope with TIMMI2. Assuming the Standard Thermal Model and combining the thermal flux in the N -band with the time-resolved absolute magnitude in optical, the derived diameter and the geometric albedo are 0.35 ( ± 0.03) km and 0.23 (+0.07, -0.05), respectively. While these values are model-dependent, we conclude that this Apollo class asteroid is of small size and its albedo is consistent with spectroscopic classification as an S-type asteroid.
