[漢羅] 木星自轉 kah 木衛公轉

木星 kah 伊 ê 衛星 ê 運動，就親像是咱 ê 太陽 kah 行星 ê 運動仝款。 木星 哪咧自旋，伊 ê 衛星 嘛哪咧踅伊行。 咱會當 ùi 追蹤木星頂懸 環形 ê 暗帶 kah 光區 ê 運動，了解 木星咧自轉。 大紅斑 是目前咱知影上大 ê 木星風暴。這支 48 秒鐘 ê 影片開始放送了後，差不多 15 秒 ê 時陣你就會看著伊踅過來矣。 這支影片 是 kā 頂個月幾若暗翕 ê 相片，用數位組合 ê 方式重新鬥做伙，變做這支 24 點鐘 ê 連紲影片。 木星上光 ê 衛星 總是踅木星 ê 行星平面咧行。 毋過地球自轉予 in 看起來 趨一爿。 咱會當佇影片內底 看著 木衛二 Europa、木衛三 Ganymede、kah 木衛一 Io。 冷吱吱 ê 加利略衛星 ùi 木星面頭前行過 ê 時陣，木衛二 Europa ê 烏影就出現 佇木星盤面頂。 木星這個月猶 佇「衝」附近，這表示講伊這馬是足光--ê。 伊欲行到離地球上倚 ê 所在矣，咱這馬是差不多規暗攏看會著伊。

[English] Jupiter Rotates as Moons Orbit

Jupiter and its moons move like our Sun and its planets. Similarly, Jupiter spins while its moons circle around. Jupiter’s rotation can be observed by tracking circulating dark belts and light zones. The Great Red Spot, the largest storm known, rotates to become visible after about 15 seconds in the 48-second time lapse video. The video is a compilation of shorts taken over several nights last month and combined into a digital recreation of how 24-continuous hours would appear. Jupiter's brightest moons always orbit in the plane of the planet's rotation, even as Earth’s spin makes the whole system appear to tilt. The moons Europa, Ganymede, and Io are all visible, with Europa's shadow appearing as the icy Galilean moon crosses Jupiter's disk. Jupiter remains near opposition this month, meaning that it is unusually bright, near to its closest to the Earth, and visible nearly all night long.
