As of April 30, 2012
The following table lists potential future Earth impact events that the JPL Sentry System has detected based on currently available observations. Click on the object designation to go to a page with full details on that object.
Sentry is a highly automated collision monitoring system that continually scans the most current asteroid catalog for possibilities of future impact with Earth over the next 100 years. Whenever a potential impact is detected it will be analyzed and the results immediately published here, except in unusual cases where an IAU Technical Review is underway.
It is normal that, as additional observations become available, objects will disappear from this table whenever there are no longer any potential impact detections. For this reason we maintain a list of removed objects with the date of removal.
Table Legend
- Coloration
- The color of the table entries gives a rough interpretation of the severity of the threat. Small objects are not likely to cause significant damage in the event of an impact, although impact damage does depend heavily upon the specific (and usually unknown) physical properties of the object in question.
Small Objects Torino Scale Colors Estimated diameter 50 meters or less. 0 1 2,3,4 5,6,7 8,9,10 - Object Designation
- Temporary designation or permanent number for this object. Assigned by the Minor Planet Center.
- Year Range
- Time span over which impacts have been detected. Typically, searches are conducted 100 years into the future.
- Potential Impacts
- The number of dynamically distinct potential impacts that have been detected by Sentry. There can be several qualitatively unique pathways to impact in a given year, e.g., some with an extra revolutions around the sun, others deflected to impact by an earlier planetary encounter.
- Impact Prob. (cum.)
- The sum of the impact probabilities from all detected potential impacts.
- Vinfinity
- The velocity of the asteroid relative to the Earth, assuming a massless Earth.
- H
- Absolute Magnitude is an intrinsic measure of brightness. It is the apparent magnitude of the object when it is 1 AU from both the sun and the observer, and at full phase for the observer.
- Est. Diam.
- The estimated diameter of the asteroid. This is an estimate based on the absolute magnitude, usually assuming a uniform spherical body with visual albedo pV = 0.154 (in accordance with the Palermo Scale) but sometimes using actual measured values if these are available. Since the albedo is rarely known for objects on this page, the diameter estimate should be considered only approximate, but in most cases will be accurate to within a factor of two.
- Palermo Scale (cum.) & (max.)
- The cumulative and maximum hazard ratings according to the Palermo Technical Impact Hazard Scale.
- Torino Scale (max.)
- The maximum detected hazard rating using the Torino Impact Hazard Scale. According to this ten-point scale, a rating of zero indicates the event has "no likely consequences." A Torino Scale rating of 1 indicates an event that "merits careful monitoring." Even higher ratings indicate that progressively more concern is warranted. The Torino Scale is defined only for potential impacts less than 100 years in the future.

The Torino
Impact Hazard Scale
Assessing Asteroid
And Comet Impact Hazard Predictions In The 21st Century
No Hazard
(White Zone) |
0
|
The likelihood
of a collision is zero, or is so low as to be effectively zero. Also applies
to small objects such as meteors and bodies that burn up in the atmosphere as
well as infrequent meteorite falls that rarely cause damage.
|
(Green Zone) |
1
|
A routine
discovery in which a pass near the Earth is predicted that poses no unusual
level of danger. Current calculations show the chance of collision is
extremely unlikely with no cause for public attention or public concern. New
telescopic observations very likely will lead to re-assignment to Level 0.
|
Meriting Attention by Astronomers
(Yellow Zone) |
2
|
A discovery,
which may become routine with expanded searches, of an object making a
somewhat close but not highly unusual pass near the Earth. While meriting
attention by astronomers, there is no cause for public attention or public
concern as an actual collision is very unlikely. New telescopic observations
very likely will lead to re-assignment to Level 0.
|
3
|
A close
encounter, meriting attention by astronomers. Current calculations give a 1%
or greater chance of collision capable of localized destruction. Most likely,
new telescopic observations will lead to re-assignment to Level 0. Attention
by public and by public officials is merited if the encounter is less than a
decade away.
|
|
4
|
A close
encounter, meriting attention by astronomers. Current calculations give a 1%
or greater chance of collision capable of regional devastation. Most likely,
new telescopic observations will lead to re-assignment to Level 0. Attention
by public and by public officials is merited if the encounter is less than a
decade away.
|
|
Threatening
(Orange Zone) |
5
|
A close
encounter posing a serious, but still uncertain threat of regional
devastation. Critical attention by astronomers is needed to determine
conclusively whether or not a collision will occur. If the encounter is less
than a decade away, governmental contingency planning may be warranted.
|
6
|
A close
encounter by a large object posing a serious but still uncertain threat of a
global catastrophe. Critical attention by astronomers is needed to determine
conclusively whether or not a collision will occur. If the encounter is less
than three decades away, governmental contingency planning may be warranted.
|
|
7
|
A very close
encounter by a large object, which if occurring this century, poses an
unprecedented but still uncertain threat of a global catastrophe. For such a
threat in this century, international contingency planning is warranted,
especially to determine urgently and conclusively whether or not a collision
will occur.
|
|
Certain Collisions
(Red Zone) |
8
|
A collision is
certain, capable of causing localized destruction for an impact over land or
possibly a tsunami if close offshore. Such events occur on average between
once per 50 years and once per several 1000 years.
|
9
|
A collision is
certain, capable of causing unprecedented regional devastation for a land
impact or the threat of a major tsunami for an ocean impact. Such events
occur on average between once per 10,000 years and once per 100,000 years.
|
|
10
|
A collision is
certain, capable of causing global climatic catastrophe that may threaten the
future of civilization as we know it, whether impacting land or ocean. Such
events occur on average once per 100,000 years, or less often.

Revised asteroid scale aids understanding
of impact risk
Astronomers led
by an MIT professor have revised the scale used to assess the threat of
asteroids and comets colliding with Earth to better communicate those risks
with the public.
The overall goal
is to provide easy-to-understand information to assuage concerns about a
potential doomsday collision with our planet.
The Torino
scale, a risk-assessment system similar to the Richter scale used for
earthquakes, was adopted by a working group of the International Astronomical
Union (IAU) in 1999 at a meeting in Torino ,
Italy . On the
scale, zero means virtually no chance of collision, while 10 means certain
global catastrophe.
"The idea
was to create a simple system conveying clear, consistent information about
near-Earth objects [NEOs]," or asteroids and comets that appear to be
heading toward the planet, said Richard Binzel, a professor in MIT's Department
of Earth, Atmospheric and Planetary Sciences and the creator of the scale.
Some critics,
however, said that the original Torino scale
was actually scaring people, "the opposite of what was intended,"
said Binzel. Hence the revisions.
"For a
newly discovered NEO, the revised scale still ranks the impact hazard from 0 to
10, and the calculations that determine the hazard level are still exactly the
same," Binzel said. The difference is that the wording for each category
now better describes the attention or response merited for each.
For example, in
the original scale NEOs of level 2-4 were described as "meriting
concern." The revised scale describes objects with those rankings as
"meriting attention by astronomers"--not necessarily the public.
Equally
important in the revisions, says Binzel, "is the emphasis on how continued
tracking of an object is almost always likely to reduce the hazard level to 0,
once sufficient data are obtained." The general process of classifying NEO
hazards is roughly analogous to hurricane forecasting. Predictions of a storm's
path are updated as more and more tracking data are collected.
According to Dr.
Donald K. Yeomans, manager of NASA's Near Earth Object Program Office,
"The revisions in the Torino Scale should go a long way toward assuring
the public that while we cannot always immediately rule out Earth impacts for
recently discovered near-Earth objects, additional observations will almost
certainly allow us to do so."
The highest Torino level ever given an asteroid was a 4 last December,
with a 2 percent chance of hitting Earth in 2029. And after extended tracking
of the asteroid's orbit, it was reclassified to level 1, effectively removing
any chance of collision, "the outcome emphasized by level 4 as being most
likely," Binzel said.
"It is just
a matter of the scale becoming more well known and understood. Just as there is
little or no reason for public concern over a magnitude 3 earthquake, there is
little cause for public attention for NEO close encounters having low values on
the Torino scale." He notes that an
object must reach level 8 on the scale before there is a certainty of an impact
capable of causing even localized destruction.
The Torino scale was developed because astronomers are
spotting more and more NEOs through projects like the Lincoln Near Earth
Asteroid Research project at MIT's Lincoln Laboratory. "There's no
increase in the number of asteroids out there or how frequently they encounter
our planet. What's changed is our awareness of them," Binzel notes.
As a result,
astronomers debated whether they should keep potential NEO collisions secret or
"be completely open with what we know when we know it," Binzel said.
The IAU working group, of which Binzel is secretary, resoundingly decided on
the latter.
The revised wording
of the scale was published last fall in a chapter of "Mitigation of
Hazardous Comets and Asteroids" (Cambridge University Press). The
revisions were undertaken through consultation with astronomers worldwide for
nearly a year before being published.
Binzel concludes
that "the chance of something hitting the Earth and having a major impact
is very unlikely. But although unlikely, it is still not impossible. The only
way to be certain of no asteroid impacts in the forecast is to keep looking."
