Future stellar encounters with the Sun might disturb the outskirts of the solar system, for close-enough passages. Such encounters may send small bodies toward the inner regions of the solar system. In the near future and among known stars, none will pass closer to the Sun than Gliese710. Here, we present an updated analysis of this topic using GaiaEDR3 data. Our new estimate confirms, within errors, those already published, but suggests a slightly closer in distance (at 0.051 0.003 pc) and later in time (in 1.29 0.04 Myr) flyby of Gliese710 to the solar system.

使用 Gaia EDR3 对 Gliese 710 未来飞越太阳系的更新:比以前的估计稍微接近和稍晚一点

未来与太阳的恒星相遇可能会扰乱太阳系的外围,以获得足够接近的通道。这样的相遇可能会将小天体送向太阳系的内部区域。在不久的将来,在已知的恒星中,没有一个会比 Gliese710 更接近太阳。在这里,我们使用 GaiaEDR3 数据对该主题进行了更新的分析。我们的新估计在误差范围内证实了已经发表的估计,但表明 Gliese710 飞越太阳系的距离稍近(0.051 0.003 pc)和时间稍晚(1.29 0.04 Myr)。
