List of asteroid close approaches to Earth in 2009

Below is the list of asteroid close approaches to Earth in 2009.

Timeline of close approaches less than one lunar distance from Earth in 2009
A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2009.

This list does not include any of the objects that collided with earth in 2009, none of which were discovered in advance, but were recorded by sensors designed to detect detonation of nuclear devices.

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.
