Let me assure you, we are in no danger of an impact from this space rock as claimed by some in the past few days (Via BIN, Mail Online and other disinfo websites and YouTubers). Asteroid 2003 QQ47 was discovered in 2003. AT THAT TIME, it was listed as a 1 on the Torino Impact Hazzard Scale. Since that time, 306 orbit observations have concluded that Earth is in no danger and the condition code for it's orbit is 0..CERTAIN. http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2003%20QQ47&orb=1 It is expected to pass the Earth by 49.9 LD, not even considered "hazardous".
In the few days after an asteroid is first discovered, its orbit is known only very approximately. The range of possible positions in future years is wide and can easily encompass the Earth, but as the object continues to be tracked, the range of possibilities shrinks quickly.
If you would like to watch the approach LIVE..
26 Mar. 2014 at 12:36 UT, the Potentially Hazardous Asteroid (143649) 2003 QQ47 will reach a minimum distance from the Earth of about 18 millions km. This is a very safe distance, so no risks at all for our planet. It will be a nice opportunity to spy this 1.5 kilometers large asteroid moving across the stars.Soon after its discovery, 2003 QQ47 received lot of attention from the media, because of a very small impact probability, soon ruled out by new observations.
As usual with these asteroids, the Virtual Telescope Project will offer a live, online event sharing real-time images of 2003 QQ47 with live commentary by our scientific staff.
The online, free session is scheduled for 26 Mar. 2014, starting at 19:30 UT.
