DA14, stadium


Sometimes it’s challenging to visualize a space object on a human scale. Artist Michael Carroll created this image size comparison of 2012DA14 (on the left) and the Chelyabinsk meteroid (on the right) shown here give us a more  understandable representation of how large the recent NEOs that have passed Earth have been.

You can read more about the size of DA14 from this JPL press release.
