說明: A previously undiscovered asteroid came within 14,000 km of Earth last week, and astronomers noticed it only 15 hours before closest approach. On Nov. 6 at around 16:30 EST a 7 meter asteroid, now called 2009 VA, came only about 2 Earth radii from impacting our home planet. This is the third-closest known non-impacting Earth approach on record for a cataloged asteroid. 一個從未被發現的一顆小行星在上週來到地球距離14000公里處,天文學家在它最接近前15個小時發現它。11月6日東部時間16:30左右7米的小行星2009 VA,來到只有約2個地球半徑距離,影響我們的家園地球 。這是史上第三名最接近的非影響地球的編目小行星。
