On September 4th at 12:46 UTC, asteroid 2012 PX had a near miss with the Earth (see STK animation above). It travelled at 10.01 km/sec relative to the Earth – that is approximately 36,000 km/h (or 22,400 mph). 2012 PX is the 23rd asteroid to be discovered in the first half of August this year and has an estimated diameter of 65-150 meters (H=23).
These near misses are not as rare as many think. In fact, during this month, our planet will have at least five close approaches with Near Earth Objects (NEOs). Follow us on Twitter and Like us on Facebook for more NEO updates.
