Afrikaans: Hierdie rolprent van asteroïde 2014 JO25 is saamgestel uit radardata wat op 19 April 2017 deur NASA se 230 voet-wye (70 meter) Deep Space Network-antenna te Goldstone, Kalifornië, verkry is. Toe waarnemings in 2014 begin het, was JO25 nog 1,53 miljoen myl (2,47 miljoen kilometer) van die Aarde af, en toe die waarnemings voltooi is, was die asteroïde reeds 1,61 miljoen myl (2,59 miljoen kilometer) weg.
Die asteroïde het 'n kontakbinêre struktuur, d.w.s. twee lobbe wat deur 'n nek verbind word. Die asteroïde se groter lob word op 2 000 voet (610 meter) in deursnee geskat. Asteroïde 2014 JO25 het die Aarde op 19 April tot binne 1,1 miljoen myl (1,8 miljoen kilometer) genader, 'n afstand wat oor die volgende 400 jaar nie geëwenaar sal word nie. Die resolusie van die radarbeelde is ongeveer 25 voet (7,5 meter) per pieksel, en 154 beelde is ingesluit. Meer inligting oor asteroïde 2014 JO25 kan op NASA se nuusblad en asteroidwatch gevind word.English: This movie of asteroid 2014 JO25 was generated using radar data collected by NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, California on April 19, 2017.
When the observations began 2014 JO25 was 1.53 million miles (2.47 million kilometers) from Earth. By the time the observations concluded, the asteroid was 1.61 million miles (2.59 million kilometers) away. The asteroid 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 (610 meters) across. Asteroid 2014 JO25 approached to within 1.1 million miles (1.8 million kilometers) of Earth on April 19. There are no future flybys by 2014 JO25 as close as this one for more than 400 years. The resolution of the radar images is about 25 feet (7.5 meters) per pixel. 154 images were used to create the movie shown.
