It was announced yesterday that the Rose Bowl-sized, "doomsday" asteroid #Apophis is roughly 20% larger than previously thought. Apophis passed us harmlessly yesterday, but it will be back in a few decades, and will swing by even closer then. So close, in fact, that it will be visible with the naked eye during the day!
