Below is the list of asteroid close approaches to Earth in 2010.

Timeline of close approaches less than one lunar distance from Earth in 2010

A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2010.[1]

This list does not include any of the objects that collided with earth in 2010, none of which were discovered in advance, but were recorded by sensors designed to detect detonation of nuclear devices.

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 (size of a person for comparison)Abs Magnitude 29-30Absolute Magnitude 28-29Absolute Magnitude 27-28Absolute Magnitude 26-27Absolute Magnitude 25-26

Notes

may have passed as close as 0.00012AU (0.05 Lunar Distances) from the Earth on January 15, 2010, but the nominal distance suggests it only passed 5 LD away.
