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. [note 2]

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.

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. [1]

  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 2021. 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.

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 in advance, 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. For a list of current Earth close approaches see Close Approaches and NEO Earth Close Approaches
  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 (0.166 LD).
  4. Objects that approached closer to the Moon than Earth are marked with a check.

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.

(456938) 2007 YV56, provisional designation 2007 YV56, is a sub-kilometer asteroid on an eccentric orbit, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 190–360 meters (620–1,200 ft) in diameter. It was discovered on 31 December 2007, by astronomers of the Catalina Sky Survey conducted at the Catalina Station in Arizona, United States.

<span class="nowrap">2014 JO<sub>25</sub></span>

2014 JO25 is a near-Earth asteroid. It was discovered in May 2014 by astronomers at the Catalina Sky Survey near Tucson, Arizona - a project of NASA's NEO (Near Earth Object) Observations Program in collaboration with the University of Arizona.

<span class="nowrap">2018 DV<sub>1</sub></span>

2018 DV1 is a micro-asteroid, classified as a near-Earth object of the Aten group, approximately 6–12 meters (20–40 feet) in diameter. It was first observed on 26 February 2018, by astronomers of the Mount Lemmon Survey at Mount Lemmon Observatory, Arizona, five days prior to its sub-lunar close encounter with Earth at less than 0.3 lunar distance.

<span class="nowrap">2018 GE<sub>3</sub></span>

2018 GE3 is a sub-kilometer asteroid on a highly eccentric orbit, classified as a near-Earth object of the Apollo group, approximately 48–110 meters (160–360 feet) in diameter. It was first observed on 14 April 2018, by astronomers with the Catalina Sky Survey one day prior to its sub-lunar close encounter with Earth at 0.5 lunar distance. It is one of the largest known asteroids (possibly the largest) in observational history to ever pass that close to Earth (also see list).

2020 LD near-Earth asteroid

2020 LD is an Apollo near-Earth asteroid roughly 140 meters in diameter. It was discovered on 7 June 2020 when the asteroid was about 0.03 AU from Earth and had a solar elongation of 154 degrees. The glare of the Sun had masked the approach of the asteroid since November 2019. The asteroid passed closest approach to Earth on 5 June 2020 at a distance of 0.002 AU. The close approach distance is now known with an accuracy of roughly ± 1000 km. This is the largest asteroid to pass closer than the Moon this year and possibly the largest since (308635) 2005 YU55 in November 2011. The asteroid makes close approaches to Mercury, Venus, Earth, and Mars. It will be brighter than apparent magnitude 24 until 18 July 2020.
