Asteroid discovered last year found to be 2 distinct objects
An asteroid first observed in December 2017 has been found to be a double asteroid with two similar-sized co-orbiting bodies. '2017 YE5' is the fourth binary near-Earth asteroid ever observed. NASA released a video which shows radar images of the pair, gathered by three of the world's largest radio telescopes- Goldstone Solar System Radar, Arecibo Observatory and Green Bank Observatory.
