List of asteroid close approaches to Earth in 2000–2007

Below is the list of asteroid close approaches to Earth in 2000–2007.

Asteroids which came closer to Earth than the Moon in 2000–2007 by time of discovery

After closest approach: 23 (43.4%)   < 24 hours before: 6 (11.3%)   up to 7 days before: 22 (41.5%)   > one week before: 0 (0.0%)   > 7 weeks before: 2 (3.8%)   > one year before: 0 (0.0%) Other years 2000-2007, 2008, 2009

Timeline of close approaches less than one lunar distance from Earth in 2000–2007

A list of known near-Earth asteroid (NEA) close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2000–2007, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS).^[1] Prior to this time period, only one asteroid each in 1991 and 1993 and two in 1994 have been observed to pass by Earth within 1 LD, but the number of discoveries picked up with the start of the first NEA surveys with dedicated telescopes in the framework of the Spaceguard programme, such as Lincoln Near-Earth Asteroid Research (LINEAR), Lowell Observatory Near-Earth-Object Search (LONEOS) and Catalina Sky Survey (CSS) from 1998, Near-Earth Asteroid Tracking (NEAT) after its expansion from 2001 and Spacewatch in its upgraded state from 2002.

The CNEOS database of close approaches lists some close approaches a full orbit or more before the discovery of the object, derived by orbit calculation. The list below only includes close approaches that are evidenced by observations, thus the pre-discovery close approaches would only be included if the object was found by precovery, but there was no such close approach in 2008. The close approaches missed by observers includes the largest object known to have passed within 1 LD during this period: 2017 VW₃, an asteroid 200–440 m (660–1,400 ft) across (H = 20.6) which passed Earth undetected at a distance of about 120,160 km (74,660 mi; 0.3126 LD; 0.0008032 AU) on 8 November 2001.

This list and the relevant databases do not consider impacts as close approaches, thus this list does not include any of the objects that collided with Earth's atmosphere in 2000–2007, which were observed visually or recorded by sensors designed to detect detonation of nuclear devices. Up to 2007, none of the asteroids destroyed in impacts have been discovered in advance.

     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)

Warning times by size

This 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.

Absolute magnitude H ≥ 30 (smallest)

(size of a person for comparison)

Absolute magnitude 30 > H ≥ 29

Absolute magnitude 29 > H ≥ 28

Absolute magnitude 28 > H ≥ 27

Absolute magnitude 27 > H ≥ 26

Absolute magnitude 26 > H ≥ 25

Absolute magnitude 25 > H (largest)

•   After closest approach: 1 (100.0%)
•   < 24 hours before: 0 (0.0%)
•   up to 7 days before: 0 (0.0%)
•   > one week before: 0 (0.0%)
•   > 7 weeks before: 0 (0.0%)
•   > one year before: 0 (0.0%)

Notes

1. Distance from the center of Earth to the center of the object. See the NASA/JPL Solar System Dynamics Glossary: Geocentric. Earth has a radius of approximately 6,400 km.
