行星会合指数与行星系质心的日心经度数据集

行星会合指数和行星系日心经度是表征行星系统运动特征的两个重要指标，在研究行星系统运动的周期性规律和分析行星系质心绕日运动特征方面发挥了重要作用。本数据集整理了1000AD至2000AD期间的行星会合指数和行星系日心经度数据，并给出了1900AD至2000AD期间行星系质心绕日运动轨迹数据和太阳质心绕太阳系质心运动轨迹数据，确定了1000AD至2000AD期间太阳系质心与太阳本体之间的位置关系。数据分析表明，行星会合指数具有明显的19.85年周期性变化规律，行星系日心经度具有明显的11.5年的周期性变化规律，行星系质心绕日运动和太阳绕太阳系质心运动都具有明显的11.5年的周期性规律；通过对1000年来太阳系质心与太阳本体位置关系的统计发现，太阳在绕太阳系质心运动过程中太阳系质心位于太阳本体内部的概率为34.5%。本数据集包括4个表格：表1是(1000AD-2000AD)行星会合指数与行星系日心经度数据；表2是(1900AD-2000AD)行星系质心绕日运动轨迹数据；表3是(1900AD-2000AD)太阳质心绕太阳系质心运动轨迹数据；表4是(1000AD-2000AD)太阳系质心与太阳本体位置关系数据。数据集存储为1个文件，.xlsx格式，数据量为172 KB。该数据集的研究成果发表在《地球物理学进展》2017年第32卷第2期上。

The planetary conjunction index (PCI) and the heliocentric longitude of the planetary system are two critical indicators characterizing the motion properties of the planetary system, which play a vital role in investigating the periodic patterns of planetary system motion and analyzing the motion characteristics of the planetary system's barycenter around the Sun. This dataset compiles the planetary conjunction index and heliocentric longitude data of the planetary system from 1000 AD to 2000 AD, and provides the motion trajectory data of the planetary system's barycenter around the Sun, as well as the motion trajectory data of the Sun's barycenter around the solar system's barycenter, for the period from 1900 AD to 2000 AD. Additionally, it determines the positional relationship between the solar system's barycenter and the Sun itself during 1000 AD to 2000 AD. Data analysis reveals that the planetary conjunction index exhibits an obvious periodic variation with a period of 19.85 years, while the heliocentric longitude of the planetary system follows a distinct 11.5-year periodic pattern. Both the motion of the planetary system's barycenter around the Sun and the motion of the Sun around the solar system's barycenter demonstrate clear periodic laws with a period of 11.5 years. Based on statistics of the positional relationship between the solar system's barycenter and the Sun itself over the past 1000 years, it is found that the probability of the solar system's barycenter being located inside the Sun itself during the Sun's motion around the solar system's barycenter is 34.5%. This dataset comprises four tables: Table 1 contains the planetary conjunction index and heliocentric longitude data of the planetary system (1000AD–2000AD); Table 2 contains the motion trajectory data of the planetary system's barycenter around the Sun (1900AD–2000AD); Table 3 contains the motion trajectory data of the Sun's barycenter around the solar system's barycenter (1900AD–2000AD); Table 4 contains the positional relationship data between the solar system's barycenter and the Sun itself (1000AD–2000AD). The dataset is stored as a single .xlsx file with a data size of 172 KB. The research findings based on this dataset were published in *Progress in Geophysics*, Volume 32, Issue 2, 2017.
