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 2020, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS). [1]

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. A number of known asteroids came closer than this in 2020, notably 2020 CW, 2020 JJ, 2020 QG, and 2020 VT4 which all approached Earth within 0.05 lunar distances. At 0.018 LD or 0.000045 AU (6,700 km; 4,200 mi), the 13 November 2020 close approach of 2020 VT4 was the closest approach of an asteroid ever observed without atmospheric contact, and still holds this record as of February 2025.

Two objects have been observed to be temporary satellites of Earth: 2020 CD3 in February 2020 and 2020 SO in September 2020, albeit the latter has been confirmed to be a rocket booster from the Surveyor 2 mission launched in 1966, leading to its de-listing as asteroid. [2]

The largest asteroid to pass within 1 LD of Earth in 2020 was 2020 LD with an estimated diameter of around 145 meters and an absolute magnitude of 22.4. The fastest asteroid to pass within 1 LD of Earth in 2020 was 2020 FD2 that passed Earth with a velocity with respect to Earth of 33.4 km/s (75,000 mph). [3] [note 2]

The CNEOS database of close approaches lists some close approaches a full orbit or more before the discovery of the object, derived by orbit calculation. The list below only includes close approaches that are evidenced by observations, thus the pre-discovery close approaches are only included if the object was found by precovery.

This list and the relevant databases do not consider impacts as close approaches, thus this list does not include any of the objects that collided with Earth's atmosphere in 2020, none of which were discovered in advance, but were observed visually or recorded by sensors designed to detect detonation of nuclear devices.

  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)

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. It shows the effectiveness of asteroid warning systems at detecting close approaches in 2020. 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.

Absolute magnitude H ≥ 30 (smallest)

Predicted close approaches

Below is the list of predicted close approaches of near-Earth asteroids larger than magnitude 27, that were predicted to occur in 2020. [note 1] This relates to asteroid cataloging systems effectiveness at predicting close approaches in 2020.

For asteroids which were observed but not predicted, see the main list above. In 2020, at the outset of the year, no asteroids were predicted to pass within 1 lunar distance of Earth. Table omitted.

Notes

  1. 1 2 Absolute magnitude 27 is the estimated magnitude of the Chelyabinsk meteor, which caused widespread damage and injury, but no deaths. Objects smaller than this are excluded.
  2. 2020 FD2 passed Earth with a velocity with respect to Earth of 33.4 km/s and was moving away from the Sun at 38.6 km/s.
  3. 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 (0.0166 LD).
  4. Objects that approached closer to the Moon than Earth are marked with a check.
  5. Precovery around this close approach: 2020-05-26
  6. As of February 2025, the closest approach ever observed without atmospheric contact

Notes

  1. For comparison
  2. 2018 VP1 could potentially pass less than 1 lunar distance to Earth, but the chances are fairly low and as such it was not listed in the main table unless followup observations confirm that it will pass less than 1 LD from Earth. A longer observation arc is required to constrain the orbit better. The Earth approach distance has an uncertainty of about 4 million km, ±3 days, and a 1:240 chance of impacting Earth.
