Below is the list of asteroid close approaches to Earth in the early years of the 21st century before any asteroid impacts had been successfully predicted.
2000–2007 | |
After closest approach: 23 (43.4%) <24 hours before: 6 (11.3%) Up to 7 days before: 22 (41.5%) > one week before: 0 (0%) > 7 weeks before: 2 (3.8%) > one year before: 0 (0%)

Timeline of close approaches less than one lunar distance from Earth in 2000-2007
editA list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2000–2007.[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 objects that collided with earth during 2000-2007, none of which were discovered in advance, but were recorded by sensors designed to detect detonation of nuclear devices.

Warning Times by Size
editThis table visualizes the warning times of the close approaches listed in the above table, depending on the size of the asteroid. The sizes of each pie chart show the relative sizes of the asteroids to scale. For comparison, the approximate size of a person is also shown. This is based around the absolute magnitude of each asteroid, an approximate measure of size based on brightness.
