可能導(dǎo)致“劇烈”天空爆炸的小行星正在接近地球

An asteroid that threatens to blast Earth with fiery debris will skim past our planet this weekend.

本周末，一顆小行星將掠過我們的星球，它可能會(huì)以燃燒的碎片撞擊地球。

The space rock is the size of a blue whale and will zip past at 14,000 miles per hour during its nerve-shredding flyby, according to NASA.

據(jù)美國(guó)國(guó)家航空航天局稱，這塊太空巖石有藍(lán)鯨那么大，在其令人緊張的飛行過程中，它將以每小時(shí)14000英里的速度飛馳而過。

The US space agency has dubbed the asteroid “2019 YB4” and says it will pass at around 10:30am GMT on Saturday.

美國(guó)航天局將這顆小行星命名為“2019 YB4”，并表示它將于周六格林威治時(shí)間上午10:30左右通過。

It’s classed as a “near-Earth object” (NEO) by NASA, tens of thousands of which are tracked by scientists to ensure they don’t collide with our planet.

它被美國(guó)國(guó)家航空和宇宙航行局(NASA)列為“近地天體”(NEO)，科學(xué)家們追蹤了數(shù)萬顆近地天體，以確保它們不會(huì)與地球相撞。

Just a small change to YB4’s trajectory would be enough to send it crashing into us, though at 86-foot long it’s not large enough to reach Earth’s surface.

YB4軌道的一個(gè)小變化就足以使它撞向我們，盡管它有86英尺長(zhǎng)，但還不足以到達(dá)地球表面。

Instead, the rock would likely explode with the force of 30 nuclear bombs as it hit our atmosphere, reports IBTimes.

據(jù)《泰晤士報(bào)》報(bào)道，這塊石頭在撞擊大氣層時(shí)可能會(huì)爆炸，威力相當(dāng)于30枚核彈。

While most of the force would be absorbed by the heavens, debris would likely shower from the sky following the blast.

雖然大部分的力會(huì)被天空吸收，但爆炸后的碎片可能會(huì)從天空中落下。

A similarly-sized asteroid that exploded over Chelyabinsk, Russia, in 2013 reportedly shattered windows and injured 1,500 people.

2013年，一顆大小類似的小行星在俄羅斯車?yán)镅刨e斯克上空爆炸，據(jù)報(bào)道打碎了窗戶，造成1500人受傷。

Fortunately, YB4 is expected to soar past Earth from a safe distance during its upcoming approach.

幸運(yùn)的是，預(yù)計(jì)YB4將在即將到來的接近中從安全距離飛越地球。
