来自太空的神秘物质今晚掠过地球

A mystery object from space is about to whiz close by Earth on Wednesday.

It will not hit the planet, but scientists are stumped by what exactly it is.

Astronomers say it could be a tiny asteroid, too small to cause damage even if it hit. It is 10 to 15 metres wide at most.

NASA says that on Wednesday at 7:47am (23:47 AEDT) it will streak by, missing Earth by about 128,750 kilometres.

It's been named 2010 AL30 according to the site Space.com.

The website also reports there was early speculation that the object was a part of a derelict spacecraft.

However, it's claimed NASA scientists ruled this out.

Paul Chodas, from the space agency, is quoted as saying, "I looked at this object closely yesterday morning and concluded that this object is probably not artificial."

"I looked at this object closely yesterday morning and concluded that this object is probably not artificial," said Paul Chodas, a scientist at NASA's Near-Earth Object Office at the Jet Propulsion Laboratory in Pasadena, Calif.

What makes 2010 AL30 weird is its orbit, which is almost exactly one Earth year long, leading to some discussion that it might be a man-made spacecraft launched in the recent past.

以上2短话听起来有些矛盾，我不排除是外星人放发过来研究地球的卫星。
