[漢羅] 土星 kah 伊 ê 六粒衛星

土星有幾粒衛星？ 這馬已經揣著 82 粒矣。 上細粒 ê 根本無夠一公里闊。 這幅圖內底有上大粒 ê 六粒 衛星，是 13 張 tùi 較光 ê 行星短時間感光，kah 13 張 tùi 較光 ê 衛星長時間感光 ê 組合圖。 這是頂個月 開 兩禮拜 ê 時間翕 ê。 In 比月球較大，嘛比 金星 閣較大淡薄仔。 土星上大粒 ê 衛星，土衛六 Titan ê 直徑是 5150 公里闊。 伊踅土星這粒 有環母行星 ê 完整運行軌道，差不多攏有翕著。 土星第一粒予人知影 ê 衛星是 Titan，伊是 1655 年 荷蘭天文學家 Christiaan Huygens 發現 ê。 毋閣 最近發現 ê 幾若粒新 ê 衛星 是 tī 2019 年發現 ê。 Tī 軌道上正爿彼粒是土星第三大 ê 衛星，土衛八 Iapetus。 畫出來 ê Iapetus 軌道半徑實在是足大 ê，所以 tī 遮干焦看會著一部份爾爾。 這個月 土星會 chhōa 木星 行過夜空，tī 日頭落山了後 ùi 東南爿 peh–起來，到 天光 進前攏看會著。

[English] Saturn and Six Moons

How many moons does Saturn have? So far 82 have been confirmed, the smallest being only a fraction of a kilometer across. Six of its largest satellites can be seen here in a composite image with 13 short exposure of the bright planet, and 13 long exposures of the brightest of its faint moons, taken over two weeks last month. Larger than Earth’s Moon and even slightly larger than Mercury, Saturn’s largest moon Titan has a diameter of 5,150 kilometers and was captured making nearly a complete orbit around its ringed parent planet. Saturn’s first known natural satellite, Titan was discovered in 1655 by Dutch astronomer Christiaan Huygens, in contrast with several newly discovered moons announced in 2019. The trail on the far right belongs to Iapetus, Saturn’s third largest moon. The radius of painted Iapetus’ orbit is so large that only a portion of it was captured here. Saturn leads Jupiter across the night sky this month, rising soon after sunset toward the southeast, and remaining visible until dawn.
