These radar images of Asteroid 1998 WT24 were obtained using NASA's 70-meter Goldstone antenna, paired with the National Radio Astronomy Observatory's Green Bank Telescope, on Dec. 10, 2015 when the asteroid was about 2.7 million miles (4.3 million kilometers) from Earth. The video compares the 2015 observations with observations of the same asteroid made in 2001.
