| 摘 要： | 为测定土星质量,对收集到的1905年至2006年期间的686次观测其中包括182次照相观测和504次CCD(电荷耦合器件)观测]通过数值积分进行拟合来改进土星的暗弱的外卫星Phoebe的轨道,并得到土星系总质量msa的新的测定值:3 497.0-1msun(太阳质量),为更精确地测定土星质量提供了一个有价值的参考值。

| Abstract: | In order to determine the mass of Saturn,the orbit of Saturnian faint outer satellite Phoebe has been improved by numerical integration via fitting to 686 observations available over 1905-2006,in which included are 182 photographic observations and 504 CCD(charge coupled device) observations.The fit yields a new determination of the total mass of Saturnian system:msa = 3 497.0-1 msun(mass of Sun).The new determination is a valuable reference in determining the mass of Saturn with better accuracy. |
