Below is the list of asteroids that have come close to Earth in 2022.

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 (0.0025696 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)
