quote:New Observations Slightly Decrease Mars Impact Probability
by Don Yeomans, Paul Chodas and Steve Chesley
Pasadena CA (JPL) Jan 03, 2008
Updated Uncertainty Region for 2007 WD5 at encounter with Mars,
shown as white dots. The thin white line is the orbit of Mars.
The blue line traces the motion of the center of the uncertainty region,
which is the most likely position of the asteroid. Note that the scale is
considerably finer than it has been in past diagrams.
Additional position observations for asteroid 2007 WD5 taken on
December 29 through January 2 have been used to improve the
accuracy of the asteroid's orbit
As a result, the range of possible paths past Mars has narrowed by
a factor of 3 and the most likely path has moved a little farther away from the planet,
causing the Mars impact probability to decrease slightly to 3.6%
(about one chance in 28).
The new positional observations were made using the 2.4 meter telescope at New Mexico
Tech's Magdalena Ridge Observatory and reported by astronomer Bill Ryan.
It seems likely that as additional observations further shrink the uncertainty region of this asteroid,
the region will no longer intersect Mars and the impact probability will quickly drop to zero.

quote:2007 WD5 Mars Collision Effectively Ruled Out As Impact Odds Widen To 1 In 10000
by Steve Chesley, Paul Chodas and Don Yeomans
forNASA/JPL Near-Earth Object Program Office
Pasadena CA (SPX) Jan 10, 2008
Since our last update, we have received numerous tracking measurements of asteroid 2007 WD5 from four different observatories. These new data have led to a significant reduction in the position uncertainties during the asteroid's close approach to Mars on Jan. 30, 2008. As a result, the impact probability has dropped dramatically, to approximately 0.01% or 1 in 10,000 odds, effectively ruling out the possible collision with Mars.
Our best estimate now is that 2007 WD5 will pass about 26,000 km from the planet's center (about 7 Mars radii from the surface) at around 12:00 UTC (4:00 am PST) on Jan. 30th. With 99.7% confidence, the pass should be no closer than 4000 km from the surface.
The sequence of updates over the last few weeks has been typical of past potential impact scenarios, with the odds of impact initially surging and later plummeting towards zero. Early on, the uncertainty region is very large and the probability of impact is rather low.
As the uncertainty narrows, but still includes the planet, the probability initially increases. But eventually, as in this case, the uncertainty region shrinks to the point that it no longer overlaps the planet, and the probability of impact begins a precipitous decline.
This rise and fall of the computed hazard was most notably seen in Dec. 2004 when asteroid 99942 Apophis briefly reached a 2.7% chance of impact with Earth in April 2029. In every case, the height and the timing of the peak probability - and the subsequent decline - cannot be known until the uncertainty region has shrunk to the point where it no longer intersects the planet.
NASA's Spaceguard Survey continues searching for Near-Earth Asteroids such as 2007 WD5, endeavoring to discover 90% of those larger than 1 km in size, a goal that should be met within the next few years. Each discovered asteroid is continually monitored for the possibility of impact. For 2007 WD5, these analyses show there is no possibility of impact with either Mars or Earth in the next century.
This unfolding story and the present results have been made possible by the tracking efforts of many astronomers at several observatories around the world:
+ 2007 WD5 was discovered using the Mt. Lemmon 1.5-meter telescope by Andrea Boattini of the University of Arizona's Catalina Sky Survey, which is led by Steve Larson.
+ Follow-up from archival images taken by the 1.8-meter telescope on Kitt Peak in Arizona were provided by Terrence H. Brezzi of the University of Arizona's Spacewatch Project, which is led by Robert McMillan.
+ Andy Puckett of the Univ. of Alaska obtained pre-discovery measurements from archival images of the Sloan Digital Sky Survey"s 2.5-meter telescope on Apache Point, NM.
+ Bill Ryan of New Mexico Tech's Magdalena Ridge Observatory observed 2007 WD5 on several crucial nights, with critical support from university and observatory staff.
+ Observations from the 6.5-meter Multi-Mirror Telescope (MMT) Observatory in Arizona were provided by a team consisting of Holger Israel (Univ. Bonn), Matt Holman (Harvard/CfA), Steve Larson (Univ. Ariz.), Faith Vilas (MMTO), Cesar Fuentes (Harvard/CfA), David Trilling (Univ. Ariz.) and Maureen Conroy (Harvard/CfA).
+ The 3.5-meter telescope at the Calar Alto Observatory in Spain provided follow-up through a team consisting of Adriano Campo Bagatin (Univ. Alicante), Gilles Bergond (Calar Alto Obs.), Rene Duffard (Inst. de Astrofisica de Andalucia), Jose Luis Ortiz (Inst. de Astrofisica de Andalucia), Reiner Stoss (Obs. Astronomico de Mallorca and Astronomisches Rechen-Institut) and Javier Licandro (Inst. de Astrofisica de Canarias).
+ Fabrizio Bernardi, Marco Micheli and Dave Tholen of the Univ. of Hawaii Institute for Astronomy observed the asteroid at its faintest using the 2.2-meter UH telescope on Mauna Kea in Hawaii.

Planetoïde mist aarde 'op haar na'quote:Een kleine planetoïde, met de naam 2007TU24, scheert op dinsdag 29 januari vlak langs de aarde. Hij passeert op een afstand van ongeveer 500.000 kilometer. In kosmische termen betekent dit dat hij de aarde op een haar na mist.
Dat heeft sterrenkundige Theo Jurriëns van de Rijksuniversiteit Groningen (RuG) vandaag bevestigd naar aanleiding van een bericht in het AD. ''Dat is overigens twee keer de afstand van de aarde naar de maan'', relativeert hij meteen. ''Dus veel merken we er uiteindelijk niet van.'' De planetoïde is een paar kilometer groot, "oftewel de doorsnede van een klein Nederlands dorp".
Het gebeurt regelmatig dat zulke voorwerpen de aarde passeren. ''In 1908 was het laatste incident met grote gevolgen", vertelt Jurriëns. In dat jaar schampte een planeetje de aarde en stortte neer boven Siberië. Het hemellichaam ontplofte toen op 10 kilometer hoogte. "De schokgolf die dat teweeg bracht, had het effect van een modale atoombom", aldus de sterrenkundige. "Gelukkig vond de explosie plaats boven onbewoond gebied."
Statistisch gezien, slaat er volgens de wetenschapper eens in de 100 à 200 jaar daadwerkelijk een planetoïde in op aarde. De meeste brokken uit de ruimte die op aarde dreigen te belanden, verpulveren in de dampkring.
2 keer afstand aarde - maan klopt natuurlijk niet, het is bij lange na nog niet eens 1,5 keer. Afstand is 384.000 kilometer, hoe ze dan bij 2x komen als het 500.000 is, is me een raadsel.quote:Op donderdag 24 januari 2008 13:04 schreef Frutsel het volgende:

Planetoïde mist aarde 'op haar na'
Near-Earth Asteroid 2007 TU24 to Pass Close to Earth on Jan. 29 - Should be Observable with Modest Sized Telescopes
Don Yeomans
NASA/JPL Near-Earth Object Program Office
January 22, 2008
Asteroid 2007 TU24, discovered by the Catalina Sky Survey on October 11, 2007 will closely approach the Earth to within 1.4 lunar distances (334,000 miles) on 2008 Jan. 29 08:33 UT. This object, between 150 and 600 meters in diameter, will reach an approximate apparent magnitude 10.3 on Jan. 29-30 before quickly becoming fainter as it moves further from Earth. For a brief time the asteroid will be observable in dark and clear skies with amateur telescopes of 3 inch apertures or larger.
The illustration below is courtesy of amateur astronomer Dr. Dale Ireland from Silverdale, WA. The illustration shows the asteroid's track on the sky for 3 days near the time of the close Earth approach as seen from the city of Philadelphia. Since the object's parallax will be a significant fraction of a degree, observers are encouraged to use our on-line Horizons ephemeris generation service for their specific locations. These personalized ephemeris tables can be generated at: http://ssd.jpl.nasa.gov/horizons.cgi?find_body=1&body_group=sb&sstr=2007%20TU24
Given the estimated number of near-Earth asteroids of this size (about 7,000 discovered and undiscovered objects), an object of this size would be expected to pass this close to Earth, on average, about every 5 years or so. The average interval between actual Earth impacts for an object of this size would be about 37,000 years. For the January 29th encounter, near Earth asteroid 2007 TU24 has no chance of hitting, or affecting, Earth.
2007 TU24 will be the closest currently known approach by a potentially hazardous asteroid of this size or larger until 2027. Plans have been made for the Goldstone planetary radar to observe this object Jan 23-24 and for the Arecibo radar to observe it Jan 27-28 and then Feb 1-4. High resolution radar imaging is expected, which may permit later 3-D shape reconstruction.

An asteroid that's likely as big as several football fields will fly past Earth next week.
Astronomers said the space rock will be visible the night of Jan. 29 to amateur astronomers with modest-sized telescopes.
Called 2007 TU24, the asteroid was discovered by NASA's Catalina Sky Survey on Oct. 11, 2007. It is estimated to be somewhere between 500 feet (150 meters) to 2,000 feet (610 meters) in diameter
The asteroid makes its closest approach to Earth, 334,000 miles (537,500 kilometers), at 3:33 a.m. Eastern time (12:33 a.m. Pacific time). For comparison, the moon is an average of 239,228 miles (385,000 kilometers) away.
"This will be the closest approach by a known asteroid of this size or larger until 2027," said Don Yeomans, manager of the Near Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif.
However, that doesn't mean we won't hear about another flyby of this nature before then.
With relatively small space rocks, like this one, astronomers sometimes don't know they're passing through until right before they do.
There is no danger of the asteroid striking Earth in the foreseeable future, the scientists said.
But if an asteroid with this size were to hit Earth, the results could be regionally devastating. The impact itself would release about 1,500 megatons of energy, creating a crater about three miles (nearly five kilometers) wide and kicking up loads of debris, according to Yeomans.
"If it hit in the ocean, which is more likely because two-thirds of the Earth is ocean, it would create a tsunami, which would be devastating for the coastlines that happen to be nearby," Yeomans told SPACE.com. "It would be a huge local problem and the tsunami would be extraordinary if it hit in the ocean."
"As its closest approach is about one-and-a-half times the distance of Earth to the moon, there is no reason for concern," Yeomans said. "On the contrary, Mother Nature is providing us an excellent opportunity to perform scientific observations."
At its nearest, the asteroid will reach an approximate apparent magnitude 10.3, which is about 50 times fainter than an object visible to the naked eye in a clear, dark sky. Then, it will quickly become fainter as it moves away.

This radar image of 2007 TU24 was obtained on January 28, 2008, about 12 hours before the asteroid's 1.4-lunar-distance pass by the Earth. The Arecibo Observatory in Puerto Rico and the Greenbank Telescope in West Virginia were used to take this image.
As expected, Asteroid 2007 TU24 made its closest approach to Earth at 12:33 a.m. today, Jan. 29 (3:33 a.m. Eastern time), and is now headed away from our planet. At its closest point, the asteroid was 554,209 kilometers (344,370 miles) from Earth, or roughly 1.4 times the distance between the moon and Earth.
January 29, 2008 Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif. had tracked the asteroid in advance and determined that there was no possibility of an impact. The rare close approach is providing a bonanza for scientists, who plan to scrutinize images and data gathered in hopes of learning more about our solar system's closest neighbors - near-Earth asteroids. More observations are planned for Feb. 1 through 4 using the Arecibo Observatory in Puerto Rico. The observatory is operated by Cornell University, Ithaca, N.Y., for the National Science Foundation.
