Table of Asteroids Next Closest Approaches to the Moon

Last update: April 19, 2024

Computations: Francesco Manca , Piero Sicoli , Augusto Testa (obs.sormano@alice.it).

This table, sorted by date for the coming years, reports asteroids with nominal Moon-miss distance within ~ 1,5 LD (Lunar Distance) .

The selection obtained among objects approaching the Earth is extrapolated from our technical lists MBPL (Minor Body Priority List) and the SAEL (Small Asteroids Encounters List) (MBPL include PHAs-Potential Hazardous Asteroids, objects with a diameter more than 240 m, SAEL takes account of smaller objects diameter less than 240 m.)

A preliminary software (developed by A. Testa - Sormano Observatory), highlights all the objects for which a close encounter is expected. Successively for each one, a more accurate investigation is computed both for nominal distance and possible error (3-sigma uncertainty confidence level) using OrbFit Software Package by F. Manca (Sormano Observatory).

Some objects are listed in the risk page at JPL (NASA) and NeoDys (Univ. Of Pisa, Italy) about possible impacts with our planet (see NeoDys Risk page and SENTRY Risk page).

All the distances are computed between the centers of mass of the bodies (Moon and asteroids). In order to refer distances from the lunar surface equatorial Moon radius needs to be taken into account.

Asteroids with interesting future close encounters with the Moon
(99942) Apophis

This large asteroid of about 325 m in diameter discovered on June 19, 2004 from Kitt Peak
Observatory (see also our internal web page for more details) according with our computations

will pass on April 14, 2029 at a nominal distance of 93476 km from the Moon's surface.

Lunar Distance (average distance between Earth and Moon) LD 384400 km
Equatorial Moon Radius Mr 1738.14 km

Table Headings:

Object:
definitive number and name or provisional designation.
Range of size:
Probable size of the object from its absolute magnitude (H). For more information on this matter see the related page at the Minor Planet Center.
Date:
Year, month, day of the close approach to the Moon.
Nominal distance:
Miss distance (from the center of mass) as resulting from nominal orbital elements.
Min and Max distance:
minimum and maximum miss possible distance based on the 3-sigma uncertainty confidence level. A simbol 'n/a' means not available, usually owing to a very high uncertainty. A symbol '(**)' means more than 1.5 million km.
