木星，太阳系中最重要的气态巨行星，也是自转速度最快的行星，不到10小时就能自转一圈。然而，这颗气态巨行星并不像固体那样旋转。木星上的一天在两极大约是9小时56分钟，在赤道附近减少到9小时50分钟。这颗巨大行星的快速旋转产生了强烈的喷流，将其云层分离成行星环带的暗带和亮带。在1月15日晚上拍摄的这组清晰的图像序列中，你可以很容易地看到木星的快速旋转，这些图像都是在法国巴黎郊外用相机和小型望远镜拍摄的。位于赤道以南，这颗巨大行星的巨大风暴系统，也被称为大红斑，可以看到随着行星的旋转从左到右移动。从左下到右上，整个序列约为2小时30分钟。

Jupiter, our Solar System's ruling gas giant, is also the fastest spinning planet, rotating once in less than 10 hours. The gas giant doesn't rotate like a solid body though. A day on Jupiter is about 9 hours and 56 minutes long at the poles, decreasing to 9 hours and 50 minutes near the equator. The giant planet's fast rotation creates strong jet streams, separating its clouds into planet girdling bands of dark belts and bright zones. You can easily follow Jupiter's rapid rotation in this sharp sequence of images from the night of January 15, all taken with a camera and small telescope outside of Paris, France. Located just south of the equator, the giant planet's giant storm system, also known as the Great Red Spot, can be seen moving left to right with the planet's rotation. From lower left to upper right, the sequence spans about 2 hours and 30 minutes.
