27颗小行星的质量是通过对扰动小行星(测试粒子)的光学和雷达观测发现的。在构建星历表EPM2011、DE423和INPOP10a时,其他作者已经确定了18个天体的质量。它们的值是基于对来自航天器的无线电信号的延迟时间的观测。对于大多数小行星,我们的数值误差较小。将我们的结果与仅基于小行星光学观测的最新测定结果进行比较,也显示了它们的准确性。
The masses of 27 asteroids are found from optical and radar observations of perturbed asteroids (test particles). The masses of 18 objects have been previously determined by other authors in the construction of ephemerides EPM2011, DE423, and INPOP10a. Their values are based on observations of the delay time of radio signals from spacecraft. Our values have smaller errors for most of the asteroids. Comparing our results with the latest determinations based only on optical observations of asteroids also shows their accuracy.
