Timeline of known close approaches less than one lunar distance from Earth in 2013

A list of known Near-Earth asteroid close approaches less than 1 lunar distance from Earth in 2013.
This list does not include any of the 24 objects that collided with earth in 2013, none of which were discovered in advance, but were recorded by sensors designed to detect detonation of nuclear devices. Of the 24 objects so detected, 5 had an impact energy greater than that of a 1 kiloton device including the 440 kiloton Chelyabinsk meteor, estimated at 20 m in diameter, which injured around 1500 people and damaged over 7000 buildings.
