List of asteroid close approaches to Earth in 2013

Add article description

Below is the list of asteroid close approaches to Earth in 2013. This was the year of the Chelyabinsk impact, in addition to the other NEO flybys

Quick Facts

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

The Chelyabinsk meteor impacted Earth in 2013 with no prior warning

A list of known Near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2013.[note 1]

  Rows highlighted red indicate objects which were not discovered until after closest approach

  Rows highlighted yellow indicate objects discovered less than 24 hours before closest approach

  Rows highlighted green indicate objects discovered more than one week before closest approach

  Rows highlighted turquoise indicate objects discovered more than 7 weeks before closest approach

  Rows highlighted blue indicate objects discovered more than one year before closest approach (i.e.
objects successfully cataloged on a previous orbit, rather than being detected during final approach)

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.

Warning Times by Size

This sub-section visualises the warning times of the close approaches listed in the above table, depending on the size of the asteroid. The sizes of the charts show the relative sizes of the asteroids to scale. For comparison, the approximate size of a person is also shown. This is based the absolute magnitude of each asteroid, an approximate measure of size based on brightness.

Abs Magnitude 30 and greater
