[漢羅] 愛按怎知影天頂彼个光點是啥物？

天頂彼个光點是啥物？ 這可能是咱定定會問 ê 問題。 這个問題會當 ùi 幾若个簡單 ê 觀察揣著答案。 比論講，伊敢有 leh 振動？抑是 leh 爍咧爍咧？ 若是有，而且若是你蹛 tī 市區，按呢彼个可能是飛龍機。 因為飛龍機實在是濟到有賰，市區 ê 光線 嘛傷光矣，kah in 比起來，恆星 kah 衛星 傷暗，看無。 若是無，而且若是你蹛 ê 所在離市區較遠，按呢彼个光點可能是 金星 抑是 火星。 若是金星，伊會 tī 日出進前抑是日頭落山了後，出現 tī 地平線附近。 有當時仔 tī 地平線附近，拄著 leh 飛 ê、較遠 ê 飛龍機，是有較困難講伊是飛龍機抑是 較光 ê 行星。 毋閣就算是按呢，咱觀察伊 ê 動作幾分鐘仔了後，to̍h 會知影伊是毋是飛龍機矣。 按呢若是猶無清楚欲按怎？ 這張圖表 雖然講有淡薄仔笑詼，毋閣嘛是會當予你袂䆀 ê 建議。 一寡較細膩 ê 天文愛好者可能會有意見，咱嘛 鼓勵 in 提供 溫柔 ê 建議。

[English] How to Identify that Light in the Sky

What is that light in the sky? Perhaps one of humanity's more common questions, an answer may result from a few quick observations. For example -- is it moving or blinking? If so, and if you live near a city, the answer is typically an airplane, since planes are so numerous and so few stars and satellites are bright enough to be seen over the din of artificial city lights. If not, and if you live far from a city, that bright light is likely a planet such as Venus or Mars -- the former of which is constrained to appear near the horizon just before dawn or after dusk. Sometimes the low apparent motion of a distant airplane near the horizon makes it hard to tell from a bright planet, but even this can usually be discerned by the plane's motion over a few minutes. Still unsure? The featured chart gives a sometimes-humorous but mostly-accurate assessment. Dedicated sky enthusiasts will likely note -- and are encouraged to provide -- polite corrections.
