    This animation shows the 3D shape of near-Earth asteroid 2000 ET70 with the Statue of Liberty for scale. The 3D model was derived from a series of 15 m (45 ft) resolution radar images taken in February 2012 using the Arecibo and Goldstone radar systems. 2000 ET70 is designated as a Potentially Hazardous Asteroid. Its close approach to Earth at the time of observations was 17 times the distance to the Moon. Additional information can be found in Naidu et al. 2013 (http://dx.doi.org/10.1016%2Fj.icarus.2013.05.025) or on http://radarastronomy.org

Since regular sky surveys began in the 1990s, astronomers have never seen an object so big come so close to our planet.
