Sormano Astronomical Observatory: TECA
Table of Asteroids Next Closest Approaches to the Earth

Last update: September 30, 2016

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


This table reports (sorted by date) asteroids with nominal Earth-miss distance within 3 Lunar Distances for the coming years.

All data have been extrapolated from our MBPL (Minor Body Priority List) and SAEL (Small Asteroids Encounters List).

Nominal miss distances in Km are computed covering a timespan up to 200 years (as a function of the orbit uncertainty), using a software developed at Sormano. Minimum and maximum values based on a 3-sigma uncertainty confidence level are computed using OrbFit Software Package by F. Manca.

Torino and Palermo Impact Hazard Scale are also reported.
Objects listed in the risk page at JPL (NASA) and NeoDys (Univ. Of Pisa, Italy) about possible impacts are signaled in column "Risk Page": NeoDys and Sentry.

Radar observations has been included in the orbital solution when available.

All the distances are computed between the centers of mass (Earth and asteroid) therefore Earth Radius should have been considered in order to refer distances to our planet surface.

A list of close encounters to the Moon (up to 1.5 LD) is also available at TAM:

Asteroids with interesting future close encounters with the Earth
2013 GM3
(diagrams of close encounter and orbital path are here available)
This small asteroid of about 25 mt in diameter, discovered on April 03, 2013 at G96 Mt. Lemmon Survey
by J. A. Johnson, will be closest to the Earth in 2026. Our computations reveal a still quite large uncertainty so
that more observations are desirable to improve the orbital elements.
Currently we estimate an Earth close approach on April 14, 2026 at a nominal distance of 68420 Km and possible
minimum transit at about 8600 Km above Earth's surface.
(153814) 2001 WN5
(diagrams of close encounter and orbital path are here available)
Discovered on November 20, 2001 at LONEOS (Lowell Observatory - Flagstaff Az)
(see our internal gallery web page ), it will pass between 238962 and 247938 Km from the Earth's surface on
June 26, 2028 .
(99942) Apophis
This large asteroid of about 325 mt in diameter, discovered on June 19, 2004 from Kitt Peak Observatory,
will pass on April 13, 2029 at a nominal distance of 31936 Km from the Earth's surface.

See our internal web page with diagrams and orbital path, when closest to the Earth Moon system.

Interesting Past Close Encounter with the Earth
( geocentric distance )

___ Box Colours ___ ______ Range of distance _____.
- Atmospheric Impact confirmed
Equatorial Earth Radii < = 10
Equatorial Earth Radii < 100
2008 TC3
For this small object the atmospheric impact has been confirmed with fragments found in Sudan
For more details see JPL News
2011 MD
This small body passed at about 12000 Km from the Earth's surface on June 27, 2011.
An animation is available by Pasquale Tricarico (Planetary Science Institute)
(367943) Duende
Soon after the discovery we alerted the international community about a possible very
close approach of this asteroid on February 15, 2013 (see the message at Minor Planet Mailing List ).
Our computations indicate that (367943) Duende (an estimated rock of about 50 meters) has passed
closest to our planet on February 15, 2013 at 19.40 GMT at 27675 Km. above Earth's surface.
The next close approach will happen on February 16, 2130 at the nominal geocentric distance
of about 942466 Km, see above list for the uncertainty.
2014 AA
As demonstrated by independent calculations by Bill Gray, MPC and Steve Chesley (JPL),
2014 AA hit the atmosphere on January 2.2, 2014. According to S. Chesley (JPL)
the impact was located just off the coast of West Africa.
(see the MPEC 2014-A02)

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. A small range reported in italic suggests that the size has been deduced directly from radar observations.
Date:
Year, month, day of the close approach to the Earth.
Nominal distance:
Miss (geocentric) distance 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 '**' means not computed, usually owing to a very high uncertainty.
The Palermo technical Scale:
Palermo Scale values between -2 and 0 indicate situations that merit careful monitoring. For more explanation see the related web page The Palermo technical Impact Hazard Scale
Torino Scale:
The Torino Impact Hazard Scale is designed to communicate to the public the risk associated with a future Earth approach by an asteroid or comet (see image below)
