The dark is a lonely place.
Since the formation of the solar system some 4 billion years ago, millions upon millions of rocks or asteroids are caught in an endless dance in orbit between Mars & Jupiter. 99.9% are no bigger than a London bus but some just some are a little larger.
Travelling at 18km per second I managed to capture movement of approx 32,000km during 30 minutes worth of exposure last night of the 320km asteroid 3 Juno. You can see from the cropped image the elongated shape due to the movement over that time. I have created a little repeating animation of the 15 frames to show the movement.
Juno was the 3rd asteroid discovered in 1804 and believed to be about the 10th largest in size.
