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.”
