NASA reports a mystery object from space will pass close by Earth on Wednesday.

Although it is reported that it will not collide with Earth the experts are not able to determine what the object is. The object was first sighted at the Skylive-Grove Creek Observatory in Australia.

Astronomers say the object that is 33 to 50 feet wide at most may be space junk or it could be a tiny asteroid, too small to cause damage even if it hit.

NASA says that on Wednesday at 7:47 a.m. EST, it will streak by, missing Earth by about 80,000 miles. In the western United States it may be bright enough to be seen with a quality amateur telescope.
