[漢羅] 太陽系內底 ê 行星:趨角 kah 自轉

毋知你上佮意 ê 行星 ê 自轉是啥物款–ê? 伊敢是踅足緊–ê?伊 ê 自轉方向是墜直–ê?坦平–ê?抑是踅倒爿–ê? 這支影片 有 kā NASA 翕–ê 太陽系 八粒行星 影像畫做動畫,按呢咱就會當看著 in 排做一排做伙自轉,咱嘛較好做比較。 Tī 這支 縮時攝影影片 內底,地球 ê 一工,就是地球自轉一輾,才幾若秒爾爾。 木星 自轉 ê 速度較緊,金星 自轉毋若較慢(是講你敢看有?),而且是踅倒爿–ê。 動畫頂半爿是岩石質 ê 太陽系內行星,大部份應該是 tī 太陽系形成早期 kah 其他天體有 激烈 ê 相挵,造成自轉方向改變。 這寡行星 ê 自轉 kah 趨角是按怎變做這馬按呢,是一个 研究主題。 這會當 ùi 現代 電腦模擬 kah 最近發現–ê 幾若百粒 系外行星 ê 分析,得著啟發。 系外行星就是 踅其他恆星咧行 ê 行星。

[English] Planets of the Solar System: Tilts and Spins

How does your favorite planet spin? Does it spin rapidly around a nearly vertical axis, or horizontally, or backwards? The featured video animates NASA images of all eight planets in our Solar System to show them spinning side-by-side for an easy comparison. In the time-lapse video, a day on Earth – one Earth rotation – takes just a few seconds. Jupiter rotates the fastest, while Venus spins not only the slowest (can you see it?), but backwards. The inner rocky planets, across the top, most certainly underwent dramatic spin-altering collisions during the early days of the Solar System. The reasons why planets spin and tilt as they do remains a topic of research with much insight gained from modern computer modeling and the recent discovery and analysis of hundreds of exoplanets: planets orbiting other stars.
