Shape Model of Asteroid (101955) Bennu Bundle V1.1

We present the three-dimensional shape of near-Earth asteroid (101955) Bennu (provisional designation 1999 RQ36) based on radar images and optical lightcurves (Nolan et al., 2013). Bennu was observed both in 1999 at its discovery apparition, and in 2005 using the 12.6-cm radar at the Arecibo Observatory and the 3.5-cm radar at the Goldstone tracking station. Data obtained in both apparitions were used to construct a shape model of this object. Observations were also obtained at many other wavelengths to characterize this object, some of which were used to further constrain the shape modeling (Clark et al., 2011; Hergenrother et al., 2013; Krugly et al., 1999).

我们基于雷达图像与光学光变曲线（Nolan等人，2013），呈现近地小行星(101955)贝努（临时编号1999 RQ36）的三维形态。贝努分别在1999年发现时的观测时段中被观测，以及2005年借助阿雷西博天文台的12.6厘米雷达与戈德斯通跟踪站的3.5厘米雷达完成观测。两次观测时段获取的数据均被用于构建该天体的形状模型。研究团队还通过多波段观测对该天体进行特征表征，其中部分观测数据被用于进一步约束形状模型的构建（Clark等人，2011；Hergenrother等人，2013；Krugly等人，1999）。
