A 'potentially hazardous' asteroid to have a close encounter with Earth on Wednesday: NASANASA：一颗潜在危险”小行星周三将与地球近距离相遇An enormous asteroid that is believed to be five times the size of the world's tallest building, Burj Khalifa, will skim past the earth Wednesday (April 29).

The asteroid, called 1998 OR2, will be at its closest approach to earth and reach within 3.

9 million miles on April 29 morning.

星期三(4月29日)，一颗据说是世界最高建筑哈利法塔5倍大小的巨大小行星将掠过地球。

这颗小行星名为1998 OR2，将在4月29日上午最接近地球，到达390万英里以内。

The details were shared by NASA through its verified Twitter account NASA Asteroid Watch.

A distance of 6.

2 million kilometres from the earth is considered a close shave in the astronomical scales involved.

NASA通过其认证Twitter账户NASA小行星观察分享了这些细节。

从天文学的角度来看，距离地球620万公里被认为是一段很近的距离。

The tweet read: "Asteroid 1998 OR2 will safely pass by Earth at a distance of 3.

9 million miles/6.

2 million km on April 29.

Astronomers studying the #asteroid with radar are also keeping a safe distance—from each other!

Just another day for #planetarydefense.

"这条推文写道：4月29日，小行星1998 OR2将在390万英里/ 620万公里的距离上安全地经过地球。

用雷达研究小行星的天文学家们彼此之间也保持着安全的距离!

又是天文馆”的一天!

”The asteroid which is estimated to measure 1.

5 miles wide, will remain at a safe distance from earth and poses no threat to our planet.

Space.

com makes it clear that the 1998 OR2 will remain "16 times further from us than the moon is from us.

"据估计，这颗小行星宽1.

5英里，将与地球保持安全距离，不会对我们的星球构成威胁。

Space.

com明确表示，1998 OR2距离我们的距离将是月球距离我们的16倍”。

"There are no asteroids that have any significant chance of hitting the Earth that is of any significant size.

There are none on our list," Paul Chodas, manager of NASA's Center for Near-Earth Object Studies.

He was at the agency's Jet Propulsion Laboratory in Pasadena, California, and said the same during a pre-recorded "NASA Science Live" webcast on Monday as quoted by the aforementioned publication.

没有任何小行星有重大机会撞击任何大小的地球。

我们的名单上没有，”美国宇航局近地天体研究中心经理保罗·乔达斯说。

他当时在该机构位于加州帕萨迪纳的喷气推进实验室，并在周一的NASA科学现场”网络直播中说了同样的话。

As per the report, NASA has created a "comprehensive" list of flybys.

It is said that scientists have discovered and tracked more than 90 percent of the near-Earth asteroids also known as NEAs.

根据这份报告，美国宇航局已经建立了一个全面”的飞行清单。

据说科学家们已经发现并跟踪了90%以上的近地小行星，也被称为NEAs。
