Timeline of known close approaches less than one lunar distance from Earth[edit]

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 2023.[1] 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. Objects coming from the direction of the Sun may not be publicly announced until a few days after closest approach. For example, 2023 AC1 was first imaged six hours after closest approach, then confirmed by other observations, but not officially announced until 3.5 days after closest approach.[2] 2023 MD4 that approached from the direction of the Sun was not first observed until 3.6 days after closest approach.[note 1] The largest asteroid on this list that is risk–listed is 2023 SM5 at about 17 meters in diameter with a 3.5-day observation arc and a 1:91000 chance of Earth impact on 2118 September 24.[3]

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.

  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. 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]

Notes[edit]

  1. ^ a b 2023 MD4 came to perihelion on 20 May 2023 and approached from the direction of the Sun. It made Earth closest approach at 20 June 2023 18:10 UT and was discovered 85.4 hours (3.56 d) later at 24 June 2023 07:36 UT.
  2. ^ Discovery date (first reported image), and if the object was confirmed and previously undiscovered, the discoverer
  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. ^ 2023 BJ7 passed 12,884 ± 334 km (8,006 ± 208 mi) from the centerpoint of the Moon around 30 January 2023 13:34 UT. Since the Moon has a radius of about 1,738 km (1,080 mi), it passed approximately 11,146 ± 334 km (6,926 ± 208 mi) from the surface of the Moon.

Beyond 1 LD[edit]

Below is an example list of near-Earth asteroids that nominally will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2023. During 2022, over 1,000 asteroids passed within 10 LD (3.8 million km) of Earth.

  Rows highlighted grey indicate a planet or main-belt asteroid

  Rows highlighted green indicate a comet which may have a larger uncertainty region due to non-gravitational forces from outgassing (sublimation).
It is also more difficult to make astrometric measurements of the precise location of the nucleus because it is masked by a fuzzy coma.

  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 cyan indicate objects that had a short observation arc with large uncertainties that were recovered and their orbits greatly refined

  Rows highlighted red indicate objects which are risk–listed with a virtual impactor near this date
