木星超過 2 小時 30 分鐘
Jupiter over 2 Hours and 30 Minutes

木星是太陽系的主宰氣態巨行星,也是自轉速度最快的行星,不到 10 小時就自轉一圈。不過,這顆氣態巨行星並不像固體天體那樣自轉。木星的一天在兩極約為 9 小時 56 分鐘,在赤道附近則縮短為 9 小時 50 分鐘。這顆巨行星的快速自轉產生了強大的噴流,將其雲層分隔成行星腰帶般的暗帶和亮帶。在這組 1 月 15 日晚拍攝的清晰影像中,您可以很容易地追蹤到木星的快速自轉,這些影像都是在法國巴黎郊外用相機和小型望遠鏡拍攝的。這顆巨行星的巨大風暴系統(又稱大紅斑)位於赤道以南,可以看到它隨著行星的自轉從左向右移動。從左下角到右上角,該序列的時間跨度約為 2 小時 30 分鐘。
原文: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.
