[漢羅] 星團 37

Tùi 大部份地球人來講，開放星團 NGC 2169 看起來就敢若是宇宙 ê 數字 37。 抑是你感覺這是數字 42？ Ùi 咱 ê 角度來看，這个無可能 ê 數字 星群 出現 tī 遮完全是巧合。 伊是 tī 獵戶座 方向 3300 光年遠 ê 所在。 Tùi 銀河系抑是開放星團來講，NGC 2169 是一个細粒星團，才 7 光年闊爾爾。 NGC 2169 ê 恆星 是 ùi 仝一團塗粉氣體生出來--ê，in ê 年歲才 1100 萬歲爾爾。 時間若長，這款 星團 tī 銀河系 內底會 拄著 其他恆星、星際雲，受著引潮力影響，就會散去。 40 外億年前，咱 ê 太陽嘛有可能是 tī 類似 ê 開放星團 內底形成--ê。

[English] The 37 Cluster

For the mostly harmless denizens of planet Earth, the brighter stars of open cluster NGC 2169 seem to form a cosmic 37. Did you expect 42? From our perspective, the improbable numerical asterism appears solely by chance. It lies at an estimated distance of 3,300 light-years toward the constellation Orion. As far as galactic or open star clusters go, NGC 2169 is a small one, spanning about 7 light-years. Formed at the same time from the same cloud of dust and gas, the stars of NGC 2169 are only about 11 million years old. Such clusters are expected to disperse over time as they encounter other stars, interstellar clouds, and experience gravitational tides while hitchhiking through the galaxy. Over four billion years ago, our own Sun was likely formed in a similar open cluster of stars.
