Near Earth Asteroid, 2012 QG42 was discovered on August 26th and will be passing Earth tonight, Thursday September 13th, 2012. Moving at 7 miles per second this asteroid is estimated to be 625 to 1,400 feet long. I was able to acquire the target last night and take a few pictures. Here’s an animation of 10 frames of the asteroid. Each frame is a 60 second exposure.
Here is a composite image of the asteroid over the 10 minute period I was photographing it.
