Another asteroid is set to make a close, but safe pass by close Earth this weekend.
The asteroid 2013 ET is between 10 to 17 metres wide - around the same size as the one which exploded over Russia last month, injuring 1000 people.
Researchers say there is no danger the asteroid will hit Earth. The asteroid will miss Earth by around 960,000km when it zips past, NBC reported.
The Virtual Telescope Project in Italy, run by astrophysicist Gianluca Masi, will webcast a live telescope view of the space rock's flyby on Friday, beginning at 2 pm EST (8am NZT on Saturday).
The 2013 EC passed by earth on Monday at around 4.30pm NZT.
The asteroid was only discovered last week by astronomers at the Mt Lemmon Observatory in Arizona.
