Below is the list of asteroids that have come close to Earth in 2022.
A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696 AU (384,410 km; 238,860 mi)) from Earth in 2022. [1] During 2022 about 124 asteroids passed within 1 LD of Earth. As most asteroids passing within a lunar distance are less than 40 meters in diameter, they generally are not detected until they are within several million km of Earth.
For reference, the radius of Earth is about 0.0000426 AU (6,370 km; 3,960 mi) or 0.0166 lunar distances. Geosynchronous satellites have an orbit with semi-major axis length of 0.000282 AU (42,200 km; 26,200 mi) or 0.110 lunar distances.
The first asteroid flyby within 1 LD of Earth in 2022 was asteroid 2021 YK (10–20 meters in diameter), which was observed on 27 December 2021 04:40 UT (when it was about 3.8 million km from Earth) and passed 0.49 LD (190 thousand km ) from Earth on 2 January 2022. The largest asteroid to pass within 1 LD of Earth in 2022 was 2022 TM2 with an estimated diameter of around 39 meters for an absolute magnitude of 25.2. The fastest asteroid to pass within 1 LD of Earth in 2022 was 2022 YW6 that passed Earth with a velocity with respect to Earth of 29.8 km/s (67,000 mph). [2] [note 1]
Two asteroids, 2022 EB5 and 2022 WJ1 , are noteworthy in that both were detected before impacting Earth. 2022 EB5 and 2022 WJ1 are the 5th and 6th successfully predicted impacts in history, respectively. The latter also holds the record for the smallest asteroid discovered while in space, with an estimated diameter less than 1 metre (3.3 ft) across. [3] Every year, dozens of asteroids impact Earth with enough force to be detected by infrasound sensors designed to detect detonation of nuclear devices, but the vast majority of impacts are unpredicted and occur without warning. Fortunately, most occur over uninhabited areas. [4]
Rows highlighted red indicate objects which were not discovered until after closest approach
Rows highlighted yellow indicate objects discovered less than 24 hours before closest approach
Rows highlighted green indicate objects discovered more than one week before closest approach
Rows highlighted turquoise indicate objects discovered more than 7 weeks before closest approach
Rows highlighted blue indicate objects discovered more than one year before closest approach (i.e.
objects successfully cataloged on a previous orbit, rather than being detected during final approach)

This sub-section visualises the warning times of the close approaches listed in the above table, depending on the size of the asteroid. It shows the effectiveness of asteroid warning systems at detecting close approaches. 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. [1]
Absolute magnitude 30 and greater
(size of a person for comparison)
Absolute magnitude 29-30
Absolute magnitude 28-29
Absolute magnitude 27-28
Absolute magnitude 26-27 (probable size of the Chelyabinsk meteor)
Absolute magnitude 25-26
Prediction accuracy for asteroids of magnitude 27 or larger nominally predicted to pass within 1 lunar distance of Earth in 2022 [note 5] |
|
Below is the list of predicted close approaches of near-Earth asteroids larger than magnitude 27, that were predicted at the start of the year to occur in 2022. [note 5] This relates to the effectiveness of asteroid cataloging systems at predicting close approaches. A predicted close approach distance of within ±50% is considered to be a successful prediction. [note 6]
For asteroids which were observed but not predicted, see the main list above.
Rows highlighted orange indicate objects which were predicted theoretically but were not observed in practice
Rows highlighted yellow indicate objects which were predicted and observed but the predicted close approach date and distance were incorrect
Rows highlighted green indicate objects which were observed with the predicted close approach distance (within ±50%) but wrong date
Rows highlighted turquoise indicate objects which were observed with the predicted close approach date but wrong distance (out by over 50%)
Rows highlighted blue indicate objects which were observed as predicted with the correct close approach date and distance
Rows in grey indicate predicted objects that are not yet due

Below is an example list of near-Earth asteroids that passed or nominally will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2022. During 2021 over 1000 asteroids passed within 10 LD (3.8 million km) of Earth.
Rows highlighted yellow indicate short arc objects that have not been observed for years and therefore the uncertainty in the approach distance and date are large
Rows highlighted red indicate objects which are risk–listed with a virtual impactor near this date

The Spacewatch Project is an astronomical survey that specializes in the study of minor planets, including various types of asteroids and comets at University of Arizona telescopes on Kitt Peak near Tucson, Arizona, in the United States. The Spacewatch Project has been active longer than any other similar currently active programs.
(152680) 1998 KJ9 is a sub-kilometer asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group. Based on absolute magnitude, it is the third largest asteroid known to have passed closer than the Moon.
2001 AV43 is a very small, monolithic asteroid and fast rotator, classified as a near-Earth object of the Apollo group, approximately 30 meters (98 feet) in diameter. It was first observed on 5 January 2001, by astronomers of the LINEAR program at Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States. The presumed S-type asteroid has a rotation period of only 10 minutes. It has an exceptionally low MOID of 0.66 lunar distance (LD) and will approach Earth at 0.81 LD on 11 November 2029.

The K-type asteroid has a rotation period of 4.8 hours. It will make a close encounter with Earth on 30 October 2071.
2019 BE5 is a sub-kilometer near-Earth asteroid classified under the Aten group. It was discovered on 31 January 2019, by the Zwicky Transient Facility at the Palomar Observatory. The asteroid was discovered one day after it had made a close approach to Earth from a distance of 0.00784 AU (1.173 million km; 3.05 LD).
(620094) 2016 AJ193 (provisional designation 2016 AJ193; also known as 2010 KV134) is a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.4 kilometres (0.87 mi) in diameter. It was discovered on 17 May 2010 by the Wide-field Infrared Survey Explorer (WISE) satellite, but was lost until it was reobserved on 16 January 2016. With an observation arc over 11 years, 2016 AJ193 has a well-determined orbit and trajectory through the year 2086. The asteroid's orbit is only potentially hazardous on a time scale of thousands of years.
2021 DW1 is a small Apollo near-Earth asteroid discovered on 16 February 2021 by the Pan-STARRS 1 survey at Haleakala Observatory, Hawaii. On 4 March 2021 at 8:59 UTC, it passed 1.48 LD (570,000 km; 350,000 mi) from Earth. During the close approach, it trailed across the Northern Hemisphere sky and brightened up to apparent magnitude of 14.6. Extensive observations of 2021 DW1 during the encounter revealed that it is an elongated, stony asteroid approximately 30 metres (100 ft) in diameter, with a rapid rotation period of 50 seconds. The asteroid's spin axis is unusually oblique relative to its orbital plane, contrary to predictions from the YORP effect.
2021 DR15 is a large trans-Neptunian object in the scattered disc, around 700 kilometres (430 miles) in diameter. It was discovered on 17 February 2021, by American astronomers Scott Sheppard, David Tholen, and Chad Trujillo using the 8.2-meter Subaru Telescope of the Mauna Kea Observatories in Hawaii, and announced on 17 December 2021. It was 89.4 astronomical units from the Sun when it was discovered, making it the ninth-most distant known Solar System object from the Sun as of December 2021. It has been identified in several precovery images as far back as 10 March 2005.
2019 EU5 is an extreme trans-Neptunian object from the scattered disc on a highly eccentric orbit in the outermost region of the Solar System. It was discovered on 5 March 2019, by American astronomers Scott Sheppard, David Tholen, and Chad Trujillo at Mauna Kea Observatories in Hawaii, and announced on 17 December 2021. It was 83.4 astronomical units from the Sun when it was discovered, making it one of the most distant known Solar System objects from the Sun as of December 2021. It has been identified in precovery images from 6 January 2016.
2022 EB5 was a small, two-metre Apollo near-Earth asteroid that disintegrated in Earth's atmosphere at 21:22 UTC on 11 March 2022, over the Arctic Ocean southwest of the Norwegian island Jan Mayen. With an atmospheric entry speed of 18 km/s (11 mi/s), the asteroid's impact generated a 4-kiloton-equivalent fireball that was detected by infrasound from Greenland and Norway. A bright flash possibly associated with the event was reported by observers from Northern Iceland.
2020 BE102 is a trans-Neptunian object in the scattered disc, around 350 kilometres (220 miles) in diameter. It was discovered on 24 January 2020, by American astronomers Scott Sheppard, David Tholen, and Chad Trujillo using the 8.2-meter Subaru Telescope of the Mauna Kea Observatories in Hawaii, and announced on 31 May 2021. It was 111.2 astronomical units from the Sun when it was discovered, making it the third-farthest known Solar System object from the Sun as of May 2022, after 2018 VG18 (124 AU) and 2018 AG37 (~132 AU).
2021 LL37 is a large trans-Neptunian object in the scattered disc, around 600 kilometres (370 miles) in diameter. It was discovered on 12 June 2021, by American astronomers Scott Sheppard and Chad Trujillo using Cerro Tololo Inter-American Observatory's Dark Energy Camera in Chile, and announced on 31 May 2022. It was 73.9 astronomical units from the Sun when it was discovered, making it one of the most distant known Solar System objects from the Sun as of May 2022. It has been identified in precovery images from as far back as 28 April 2014.
2021 RR205 is an extreme trans-Neptunian object discovered by astronomers Scott Sheppard, David Tholen, and Chad Trujillo with the Subaru Telescope at Mauna Kea Observatory on 5 September 2021. It resides beyond the outer extent of the Kuiper belt on a distant and highly eccentric orbit detached from Neptune's gravitational influence, with a large perihelion distance of 55.5 astronomical units (AU). Its large orbital semi-major axis (~1,000 AU) suggests it is potentially from the inner Oort cloud. 2021 RR205 and 2013 SY99 both lie in the 50–75 AU perihelion gap that separates the detached objects from the more distant sednoids; dynamical studies indicate that such objects in the inner edge this gap weakly experience "diffusion", or inward orbital migration due to minuscule perturbations by Neptune. While Sheppard considers 2021 RR205 a sednoid, researchers Yukun Huang and Brett Gladman do not.
