旅行者号红外光谱仪和辐射计(IRIS)的调查数据被用来确定天王星的反照率、有效温度和能量平衡。根据15°<；α<；155°相角范围内的宽带辐射观测，得到了测辐射热键反照率的轨道平均值A=0.300±0.049，由此得到平衡温度Teq=58.2K±1.0K。这比之前确定的数值有了很大的改善。因此，天王星的能量平衡为E=1.06±0.08；1.14的一个标准误差上限低于以往的结果。
Data from the Voyager infrared spectrometer and radiometer (IRIS) investigation are used to determine the albedo, effective temperature, and energy balance of Uranus. From broadband radiometric observations made over a range of phase angles 15° < α < 155°, an orbital mean value for the bolometric Bond albedo, A = 0.300 ± 0.049 , is obtained, which yields an equilibrium temperature Teq= 58.2 ± 1.0°K. From thermal spectra obtained over latitudes from pole to pole, an effective temperature Teff= 59.1 ± 0.3°K is derived. This represents a substantial improvement over previously determined values. The energy balance of Uranus is therefore E = 1.06 ± 0.08; the one-standard-error upper limit of 1.14 is lower than previous results.
