帝國(guó)大廈大小的小行星，“預(yù)計(jì)”將與地球擦肩而過(guò)

A “potentially hazardous” asteroid the size of the Empire State Building will come within striking distance of the Earth on Aug. 10 — but is expected to zoom by without incident, according to NASA.

據(jù)美國(guó)宇航局稱(chēng)，8月10日，一顆帝國(guó)大廈大小的“潛在危險(xiǎn)”小行星將接近地球，并與地球保持一定距離，但預(yù)計(jì)它將會(huì)與地球擦肩而過(guò)，不會(huì)發(fā)生任何事故。

The space rock — designated as a near-Earth object, because its orbit takes it within 30 million miles of Earth — is expected come within about 4.55 million miles of the planet as it whizzes by us at 10,400 mph.

這塊太空巖石被稱(chēng)為近地天體，因?yàn)樗能壍谰嚯x地球不到3000萬(wàn)英里，當(dāng)它以每小時(shí)10400英里的速度從我們身邊疾馳而過(guò)時(shí)，預(yù)計(jì)距離地球大約455萬(wàn)英里。

Anything that gets closer than 0.05 “astronomical units” — roughly 4.65 million miles — is considered “potentially hazardous.”

任何接近0.05“天文單位”(約465萬(wàn)英里)的物體都被認(rèn)為是“潛在危險(xiǎn)”。

The asteroid, dubbed 2006 QQ23, is 1,870 feet in diameter — some 36 stories larger than the 1,454-foot-tall Empire State Building.

這顆小行星被命名為2006 QQ23，直徑1870英尺，比1454英尺高的帝國(guó)大廈大36層。

It hasn’t gotten this close to our terrestrial home since 2001, when it came within 3.13 million miles, according to data from NASA’s Center for Near-Earth Object Studies

據(jù)美國(guó)國(guó)家航空航天局近地天體研究中心的數(shù)據(jù)，自2001年以來(lái)，它從未如此接近我們的地球家園，當(dāng)時(shí)距離地球不到313萬(wàn)英里。

2006 QQ23’s next near-Earth appearance is expected on Feb. 15, 2022, but it won’t come nearly as close, data shows.

數(shù)據(jù)顯示，QQ23下一次近地探測(cè)預(yù)計(jì)將在2022年2月15日，但它不會(huì)接近地球。
