Below is the list of asteroid close approaches to Earth in 2016.

Timeline of known close approaches less than one Lunar distance from Earth in 2016

A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696abbr=onNaNabbr=on) from Earth in 2016.[1]

For reference, the radius of Earth is approximately 4.26E-05abbr=onNaNabbr=on or 0.0166 Lunar distances.
The orbit of geosynchronous satellites, however, is 0.000282abbr=onNaNabbr=on or 0.110 Lunar distances. This year, 6 (possibly 7) asteroids traveled nearer than this, most notably, which approached a mere 1.25 Earth radii (8000 km) from the surface.

While most asteroids on this list are confirmed, well-observed unconfirmed objects with a 50% or greater chance of passing within 1 LD of the Earth are included as well.

This list does not include any of the 32 objects that collided with earth in 2016, none of which were discovered in advance, but were recorded by sensors designed to detect detonation of nuclear devices (of the 32 objects detected 4 had an impact energy greater than that of a 1 kiloton device).[2]

Warning Times by Size

This sub-section visualizes 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 Absolute Magnitude less than 25 (largest)

Notes

Timeline of close approaches less than one Lunar distance from the Moon in 2016

The number of asteroids listed here are significantly less than those of asteroids that approach Earth for several reasons. Asteroids that approach Earth not only move faster, but are brighter and are easier to detect with modern surveys because:

These factors severely limit the amount of Moon-approaching asteroids, to a level many times lower than the asteroids detected passing as close to Earth.

Other objects

XF38FAC (Satellite 2015-007B) with an observation arc of only 17 minutes was estimated to have a chance of impacting Earth at 16:51 on 20 March 2016,[130] but turned out to be the SpaceX Falcon 9 second stage that sent Deep Space Climate Observatory out to L1.

  39. The nominal approach of 2016 FN56 to Earth was 0.0025694 AU, or roughly 23.5 kilometers closer than 1 Lunar distance. However, the error in this close approach totals roughly 0.000207 AU or 31,000 kilometers, making the chance that it actually did pass within 1 Lunar distance of Earth an almost exact 50-50 chance- a 49.9994%:50.0006% chance, to be specific.
