它因為是到達地球之前就被這樣的機構觀測和追蹤的第一顆小行星而受到重視<ref name="Roylance2008" />。檢測和追蹤[[近地小行星]]的過程，是對[[太空警衛]]努力的驗證和考驗。在少於19小時的時間內，總數達到586次的天體測量和幾乎同數量的光度觀測報告，由27位業餘和專業的天文學家通報給[[小行星中心]]，在撞擊前11小時共發出了25封小行星軌道解，提供了進一步觀測的方案。在10月7日01:49（世界時）<ref name="jplneo"/>，小行星進入地球的陰影內，因而無法做進一步的觀測。

=== 分析 ===
第六站隕石的樣品由詹尼斯肯斯領導的合作單位分析，第六站的合作單位包括NASA在加州的[[艾美斯研究中心]]、[[休斯頓]]的[[林顿·约翰逊太空中心|詹森太空中心]]、[[華盛頓卡內基學會]]、和[[紐約市]]的[[福特漢姆大學]]。第一個樣品測量到異常的超細顆粒：多孔的[[礫岩 (地質)|複相碎屑岩]][[橄輝無球粒隕石]][[無粒隕石]]，與大的[[碳質球粒隕石|碳質顆粒]]。

隕石的反射光譜，結合天文觀測，確定小行星2008 TC3是[[F-型小行星]]。異常脆弱的富含碳的橄輝無球粒隕石，現在與F-型小行星有著緊密的連結<ref name="Jenniskens2009" />。在隕石中也發現了[[胺基酸]]<ref>{{cite web

=== 完美的結局 ===
這顆天體的發現者理查德·科瓦斯基收到第六站隕石的一個小碎片，是來自小行星郵寄清單上的一位好心朋友贈送的禮物。因為科瓦斯基的發現，讓業餘和專業的天文學家為一個微小的碎片而合作、連結在一起<ref>{{cite web
