NASA Radar Spots Large, Peanut-Shaped Asteroid Prior to Flyby
Added Apr 24, 2017 | Rate View top rated
NASA's Goldstone Solar System Radar (located in California's Mojave Desert) collected and generated images of asteroid 2014 JO25 on April 18, 2017. At the time, the relatively large asteroid was 1.9 million miles from Earth. Asteroid 2014 JO25 was first discovered in May 2014, and has a contact binary structure - two lobes connected by a neck-like region. The largest of the asteroid's two lobes is estimated to be 2,000 feet across. The asteroid safely passed Earth at a distance of 1.1 million miles on April 19. The encounter is the closest the object will have come to Earth in 400 years and will be its closest approach for at least the next 500 years.
