National Geographic has published a great data visualization that compares the estimated size of the asteroid "Spooky" discovered only a few weeks ago with the well-known skyscrapers in New York City, Asteroid Called ‘Spooky’ Will Buzz Earth on Halloween
Astronomers from NASA's Near Earth Object Program first spotted the incoming asteroid on October 10, just three weeks before its closest approach. It was too small and faint to detect until it came within the range of large survey telescopes.
Nicknamed Spooky, the asteroid (officially called 2015 TB145) is estimated to be about 950 to 2,100 feet wide (290 to 650 meters). Scientists won't be sure of its exact size until they can do radar measurements—and the most accurate will be on Halloween, when it passes the closest.
This is a perfect way to use data visualization to put the information into perspective for the audience. It would be nice to have more of the building identified.
