Dr. Campins at the Planetary Science Institute of SAI Corporation will use this grant to continue a study of the properties of the nuclei of Earth-approaching comets. This study involves a new observational approach which proved very successful in recent work on Comets Neujmin 1 and Arend-Rigaux. These observations will yield size, albedo, color, approximate shape, and rotational characteristics of the nuclei of seven comets. Knowledge of the physical properties of comet nuclei for a large sample of comets will allow general conclusions to be drawn about the processes that create these properties, about the relationship between comets and other minor bodies in the Solar System, and about the role that comets play in the cratering processes on planets.

SAI公司行星科学研究所的坎平斯博士将利用这笔赠款继续研究接近地球的彗星核的性质。这项研究涉及一种新的观测方法，在最近关于Neujmin1和Arend-Rigaux彗星的工作中被证明是非常成功的。这些观测将得出七颗彗星的核的大小、反照率、颜色、近似形状和旋转特征。对大样本彗星的彗核物理性质的了解将使我们能够得出关于产生这些性质的过程、关于彗星与太阳系中其他次要物体之间的关系以及关于彗星在行星上的陨石坑过程中所起的作用的一般性结论。
