Rosetta's 'Rubber Ducky' Comet Compared to Los Angeles

Just how big is your average comet? Experts say that the average comet has a nucleolus that reaches out to about 6 square miles, That makes the comet that the European Space Agency's Rosetta spacecraft just recently chased down up-to three times smaller than some of its brethren. Those figures truly don't give this enormous space rock justice. Now, a new photo has been circulating the twittersphere that has people in awe of what they thought was a "tiny" comet.
