如果把时间向前推几年，当有人问你太阳系的哪个行星的卫星最多的时候，你一定会毫不犹豫的回答：是土星。但是这几年天文学家们的新发现使这个问题变得很难回答。如果你浏览一下过去几年的新闻，就会发现，木星和土星的卫星的数目经常被改写，这有点像跳高运动员布勃卡每次打 If you push time forward for a few years, when someone asks you which planet of the solar system has the most satellites, you will certainly answer without hesitation: it is Saturn. But new discoveries by astronomers in recent years have made this problem difficult to answer. If you look at the news of the past few years, you will find that the number of moons of Jupiter and Saturn are often rewritten, which is a bit like the high jumper Bubka hits every time.
