[漢羅] 遠方 ê 小行星

逐工攏有 ùi 太空掔過來地球 ê 石頭。是講，較大粒 ê 石頭嘛較罕 leh 挵著地球。逐工攏有足濟幾若公斤重 ê 太空塗粉挵著地球。較大粒 ê 挵著 to̍h 會變做發光 ê 流星。逐工攏有 kah 籃球平大粒 ê 石頭 kah 冰丸落落來地球 ê 大氣層。大部份攏足緊 to̍h 蒸發了了矣。Tùi 地球會造成 嚴重威脅 ê 石頭嘛有。直徑差不多有 100 公尺遐爾大。In 差不多每 1000 年才 挵著地球 一擺。遮爾大粒 ê 石頭若是掔著海，to̍h 會引起 足恐怖 ê chu-ná-mih，閣有 可能毀滅 海岸線。若是欲予超過一公里大 ê 大粒小行星 摃著 ê 機會 ē 閣較少。一般來講，愛幾若百萬年才會拄著一擺。毋過，這會 造成全球性 ê 災難。其實猶有足濟小行星 猶未去予人揣著。Tī 這張影像 內底，有一粒畫一逝藍線 ê 小行星，to̍h 是按呢 tī 1998 年去予哈伯太空望遠鏡揣著 ê。大粒小行星 kah 地球 相碰，並無啥會 影響著地球 ê 軌道。顛倒是相碰 產生 ê 塗粉，會影響著 地球 ê 氣候。有一款結果是造成全球足濟物種 ê 滅絕。這款講法，可能會減弱 地球物種 sī 因為人類活動 chiah 慢慢滅絕 ê 假設。

[English] Asteroids in the Distance 

Rocks from space hit Earth every day. The larger the rock, though, the less often Earth is struck. Many kilograms of space dust pitter to Earth daily.Larger bits appear initially as a bright meteor . Baseball-sized rocks and ice-ballsstreak through our atmosphere daily,most evaporating quickly to nothing. Significant threats do exist for rocks near 100 meters in diameter, which strike the Earth roughly every 1000 years. An object this size could cause significant tsunamis were it to strike an ocean, potentially devastating even distant shores.A collision with a massive asteroid ,over 1 km across, is more rare ,occurring typically millions of years apart, but could have truly global consequences .Many asteroids remain undiscovered . In fact, one was discovered in 1998 as the long blue streak in the above archival image taken by the Hubble Space Telescope.A collision with a large asteroid would not affect Earth's orbit so much as raise dust that would affect Earth's climate . One likely result is a global extinction of many species of life,possibly dwarfing the ongoing extinction occurring now .
