Ready for a "Spooky" close-up? NASA is showing off high-res images of the 400-meter-wide (1,300 feet) asteroid that zipped past Earth on Halloween, revealing its eerie skull-like face.
Nicknamed "Spooky" for its skull-resembling shape, the asteroid - otherwise known by its NASA classification as 2015 TB145 - was flying 480,000 kilometers from Earth when it passed on October 31. It was impossible to see that far away, but now NASA pictures allow us to take a closer peek.
The agency used huge, Earth-based radio telescopes and antennas to capture the images. By bouncing radar signals off the asteroid, NASA created a detailed picture of Spooky's surface.
"The radar images of asteroid 2015 TB145 show portions of the surface not seen previously and reveal pronounced concavities, bright spots that might be boulders, and other complex features that could be ridges," said Lance Benner, who leads NASA's asteroid radar research program at its jet propulsion laboratory in Pasadena, California.
