Below is the list of asteroid close approaches to Earth in 2019.

{{anchor|List}} 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 ({{convert|0.0025696|AU|km mi|abbr=on}}) from Earth in 2019.[1]

For reference, the radius of Earth is approximately {{convert|0.0000426|AU|km mi|abbr=on}} or 0.0166 lunar distances.
Geosynchronous satellites have an orbit with semi-major axis length of {{convert|0.000282|AU|km mi|abbr=on}} or 0.110 lunar distances. The only known asteroid to have passed this distance from Earth was the 1-2 meter {{mpl|2019 AS|5}}

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.

Notes

1. ^For a list of current Earth close approaches see NEO Earth Close Approaches
2. ^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.
3. ^Distance error: 0.0012 AU, approach range: 0.40 to 1.36 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
4. ^Distance error: 0.000420 AU, approach range: 0.016 to 0.25 LD. There was a roughly 2% chance of impact. The asteroid is most likely between 1 and 14 meters across, so would probably be detectable. The asteroid is unconfirmed and will likely never receive a provisional designation.
5. ^distance error: 0.0008 AU, approach range: 0.27 to 0.90 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
6. ^distance error: 0.0010 AU, approach range: 0.30 to 1.07 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
7. ^the asteroid is unconfirmed and will likely never receive a provisional designation.
8. ^distance error: 0.0004 AU, approach range: 0.39 to 0.70 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
9. ^Distance from the center of the Moon to the center of the object. The Moon has a radius of approximately 1,740 km.
10. ^Distance error: 0.0010 AU, approach range: 0.54 to 1.32 LD. The asteroid is unconfirmed and will likely never receive a provisional designation.
11. ^the asteroid is unconfirmed and will likely never receive a provisional designation.
12. ^The asteroid could potentially pass less than 1 lunar distance to Earth, but the chances are fairly low and as such it isn't listed in the main table unless followup observations confirm that it will pass less than 1 LD from Earth.
13. ^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.

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

Listed are asteroids that are included on the Sentry Risk Table because they have short observation arcs with poorly constrained orbits and have a chance of impacting Earth in 2019. 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, {{mp|2008 SH|148}} is expected to be {{Convert|5.3|AU|e6km|sigfig=1|abbr=unit|lk=on}} from Earth in October 2019 around the time of the virtual impact.

Cumulatively among the asteroids listed below, there is a roughly 1 in 16,500 chance that any of the asteroids will impact Earth in 2019. Most of this comes from asteroid {{mpl|2006 QV|89}} which has a 1 in 20,000 chance of impact on 9 September 2019. An impact from this asteroid is highly unlikely as there is only a 0.4% chance that the observations made of it in 2006 would fit to the 'impacting' orbit.

Also included are asteroids discovered before impact 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.
