It's 'one of the most elongated' asteroids ever seen.
NASA's Jet Propulsion Laboratory in Southern California closely tracked one of the most elongated asteroids ever imaged by planetary radar as it flew within 1.1 million miles of Earth on February 3.
The Earth was never at risk of an impact from 2011 AG5, but NASA's JPL made valuable observations as it flew by earlier this month. Thanks to these observations, scientists at NASA were able to determine the asteroid's size, rotation, shape, and also a number of surface details.
