The asteroid, coincidentally observable during the biennial school, was 1.14 times the Earth-Moon distance at its closest (about 440,000 km or 270,000 miles), its closest approach to Earth until at least 2178. https://phys.org/news/2015-07-football-asteroid-students-naicnrao.html Space Exploration Thu, 16 Jul 2015 06:08:04 EDT news356245676 Scientists from the Arecibo Observatory captured images of the asteroid 1999 FN53, which was visible since this past Tuesday until today Friday, May 15, 2015. https://phys.org/news/2015-05-image-asteroid-fn53.html Space Exploration Wed, 20 May 2015 04:39:31 EDT news351315554 (Phys.org) -- Using the planetary radar system at Arecibo Observatory, astronomers have determined that asteroid 2012 LZ1 is twice as large as originally estimated based on its brightness, and large enough to have serious global consequences if it were to hit the Earth. However, a new orbit solution also derived from the radar measurements shows that this object does not have any chance of hitting the Earth for at least the next 750 years. https://phys.org/news/2012-06-arecibo-observatory-asteroid-lz1-big.html Space Exploration Thu, 21 Jun 2012 17:45:33 EDT news259519450
