Below is the list of asteroid close approaches to Earth in 2018.

Timeline of known close approaches less than one lunar distance from Earth

A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696AU) from Earth in 2018.^[1]

For reference, the radius of Earth is approximately 4.26E-05AU or 0.0166 lunar distances.
Geosynchronous satellites have an orbit with semi-major axis length of 0.000282AU or 0.110 lunar distances. Eight known asteroids (2018 BD, A106fgF, 2018 LA, A107j4q,, 2018 UA,, and) are confirmed to have passed within this distance, and poorly-observed asteroids ZB0A262,, ZGBE54F, A1080DC, ZW87F01, and ZW900BE may have also passed within this distance.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.

The largest asteroid to pass within 1 LD of Earth in 2018 was with an estimated diameter of around 137 meters and an absolute magnitude of 22.5. The fastest asteroid to pass within 1 LD of Earth in 2018 was that passed Earth with a velocity with respect to Earth of 29.6km/s.^{[2] [3]}

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 Absolute Magnitude less than 25 (largest)

Notes

Timeline of close approaches less than one lunar distance from the Moon

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:

• Asteroids that come closer to Earth are a higher priority to confirm, and only confirmed asteroids are listed with a lunocentric approach distance.
• Those that closely approach the Moon are frequently lost in its glare, making them harder to confirm. They are similarly hard to discover during the new moon, when the Moon is too close to the Sun to detect asteroids while they are near the Moon.

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.

Virtual Impactors

List of asteroids that are listed on the Sentry Risk Table because they have short observation arcs with poorly constrained orbits and have a chance of impacting Earth in 2018. Given a short observation arc, many different orbits fit the observed data. These objects could be millions if not billions of kilometers from Earth on the date of a low probability virtual impactor. For example, is expected to be 5AU from Earth in December 2018 around the time of the 3 virtual impactors.^[33] 2010 GZ60 was removed from the sentry table in February 2018 after further observations were found by NEOWISE, ruling out any possible impacts.

Cumulatively among the asteroids listed below, there is a roughly 1 in 98,700 chance that any of the asteroids will impact Earth in 2018. Most of this comes from asteroid 2008 US which is only ~2 meters in diameter and had a 1 in 240,000 chance of impact on 18 April 2018.

Also included are asteroids discovered before impact (specifically, 2018 LA) and exceptionally massive fireballs with either an equivalent yield of more than 1 kiloton of TNT or an estimated size of more than 3 meters.

7. Largest known asteroid to pass so close to Earth since in 1971.
8. distance error: 0.0000107 AU, approach range: 0 to 0.0052 LD. Assuming the observations were not made in error, there was a (~9%) this asteroid hit the Earth (Impact path). However, there was no record of an impact reported, so if it did indeed impact Earth, it was likely in an uninhabited region or in the Pacific ocean. (The further west in the impact path, the larger the asteroid would be. If it hit west of Africa or in the Indian ocean, it would have been several meters across and have been recorded.) The asteroid is unconfirmed and will likely never receive a provisional designation.
9. distance error: 0.000305 AU, approach range: 0.037 to 0.27 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
10. AU, approach range: 0.018 to 1.157 LD. There is no chance that it impacted Earth, as the minimum distance (0.018 LD) is still roughly 410 kilometers above Earth's surface.
11. distance error: 0.000347 AU, approach range: 0.047 to 0.32 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
12. 2018 LA was estimated to have an 82% chance of impacting Earth somewhere between the central Pacific ocean and Africa (Impact path). Several reports have come from South Africa and Botswana confirming that it did indeed impact in central Africa
13. distance error: 0.00000608 AU, approach range: 0.078 to 0.082 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
14. distance error: 0.000184 AU, approach range: 0.13 to 0.28 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
15. distance error: 0.000296 AU, approach range: 0.40 to 0.63 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
16. distance error: 0.0000651 AU, approach range: 0.085 to 0.136 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
17. distance error: 0.000600 AU, approach range: 0.43 to 0.89 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
18. distance error: 0.0000181 AU, approach range: 0.100 to 0.115 LD.
19. distance error: 0.0000114 AU, approach range: 0.325 to 0.333 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
20. distance error: 0.000583 AU, approach range: 0.017 to 0.46 LD. The asteroid is unconfirmed and will likely never receive a provisional designation. There is no chance of impact as the asteroid was discovered after its closest approach.
21. distance error: 0.000165 AU, approach range: 0.023 to 0.152 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
22. Distance from the center of the Moon to the center of the object. The Moon has a radius of approximately 1,740 km.
23. distance error: 0.000633 AU, approach range: 0.33 to 0.82 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.

25. distance error: 0.00000167 AU, approach range: 0.9942 to 0.9955 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
26. distance error: 0.000198 AU, approach range: 0.73 to 0.89 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
27. distance error: 0.000194 AU, approach range: 0.58 to 0.73 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
28. distance error: Unknown, Approach range: Unknown. The asteroid is unconfirmed and will likely never receive a provisional designation.

31. distance error: 0.0000329 AU, approach range: 0.943 to 0.968 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
32. distance error: 0.0000552 AU, approach range: 0.972 to 1.015 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.

34. This is a measurement of how far off of the "best fit" orbit the asteroid would have to have for it to hit at this time. Further values from 0 mean that the measured positions of the asteroid used to calculate its orbit would need to be highly inaccurate for it to hit Earth. For reference, 1.0/-1.0=31.7% odds the observations would be this inaccurate, 2.0/-2.0=4.6% odds, 3.0/-3.0=0.27% odds.
