| The 460-foot-long Asteroid 2013 ET has whizzed past Earth on Saturday - the latest in our planet’s galactic ‘pinball contest’. Earlier in the day, the 2013 EC20 passed even closer, and both within a month of the Chelyabinsk meteor’s Earth strike. The enormous piece of space debris has passed just 2.5 lunar distances from planet Earth – the moon is approximately 384,400 km (238,000 miles) from us, meaning the asteroid’s flyby will be at a distance of about 950,000km (600,000 miles). Some astronomers have compared its size to that of a city block, others a football pitch. Its dimensions were widely given as 460 feet (140m) long and 210 feet (64m) wide. A professional American football field is 360 feet by 160 feet, which would make this asteroid 100 feet longer than a football field, and 50 feet wider, should it live up to calculations. source: http://rt.com/news/asteroid-earth-flyby-saturday-028/ | |
