Fewer large asteroids- 24OCT09

Fewer large asteroids than as predicted


And now, from the pessimists...

A fine theory and simulation. A shame it doesn't
correspond in any way to reality. The impact rate
on terrestrial planets starts out very high at the
beginning of the solar system, declines for half
a billion years then rises again in a final flurry of
accretion and clean-up, at 3.9 billion years ago.
The rate declines in a fairly uniform manner
thereafter, but about 600-to-400 million years
ago, it suddenly climbs to a level not seen since
3.4 billion years ago, and it is STILL at that
higher level today.

This is from the actual impact record, not having-
fun-with-your-computer-model science kit. The
data is from impact spherules in the lunar regolith
and the graph of the impact rates throughout
time can be found on page 660 of:
http://muller.lbl.gov/papers/lunar_impacts_Nemesis.pdf


More information here:
http://www.bibliotecapleyades.net/ciencia/ciencia_nemesis08.htm


True, this researcher thinks it might be proof of
a big comet infall due to an undiscovered companion
small star to the Sun, but so what? It might be, but
the immediate mechanism is likely to be asteroidal
breakup.

The timing matches perfectly with the breakup of
the L-chondrite parent body, the largest asteroidal
breakup in the past few billion years or so. The
evidence and timing for that is presented here:
http://www.psrd.hawaii.edu/Mar04/fossilMeteorites.html


At about 480 million years ago (Ordovician times),
the meteorite fall rate on the Earth was 100 TIMES
GREATER than it is today, during the peak of that
breakup episode.

The history of the formation of the 50 or so asteroidal
families unambiguously identified does not match this
pretty little theory in the least. Reality is contingent,
accidental, and randomly chaotic, and NOT "well
described with a logarithmic decay law."

Asteroid to Fly By Earth Wednesday 17MAR09

Asteroid to Fly By Earth Wednesday
Jet Propulsion Laboratory
March 17, 2009
PASADENA, Calif. -

A small asteroid will fly past Earth early tomorrow morning (Wed., March 18). The asteroid, 2009 FH, is about 50 feet (15meters) wide. Its closest approach to Earth will occur at 5:17 a.m. PDT(8:17 a.m. EDT, 12:17 UTC) at an altitude of about 49,000 miles (79,000kilometers)."This asteroid flyby will be a good viewing opportunity for both professional and amateur astronomers," said Don Yeomans of the Near-Earth Object Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "The asteroid poses no risk of impact to Earth now or for the foreseeable future."NASA detects and tracks asteroids and comets passing close to Earth. The Near Earth Object Observation Program, commonly called "Spaceguard,"plots the orbits of these objects to determine if any could be potentially hazardous to our planet.For more information, visit: http://neo.jpl.nasa.gov/

ASTEROID BUZZES EARTH 17MAR09

Space Weather News for March 17, 2009
http://spaceweather.com
ASTEROID BUZZES EARTH: Newly-discovered asteroid 2009 FH is flying past Earth tonight only 85,000 km (0.00057 AU) away. That's a little more than twice the height of a geosynchronous communications satellite. Experienced amateur astronomers in North America can photograph the 20-meter-wide space rock racing through the constellation Gemini after sunset on March 17th. It should be about as bright as a 14th magnitude star.

Please visit http://spaceweather.com for an ephemeris and updates.

This is the second time in March that an asteroid has flown so close to Earth. On March 2nd, 2009 DD45 passed by only 72,000 km away. Measuring some tens of meters in diameter, 2009 DD45 and 2009 FH are approximately Tunguska-class objects, meaning they pose no global threat but could cause local damage if they actually hit Earth. In years past, asteroids of this size often passed unnoticed, but recent improvements in asteroid surveys have resulted in growing numbers of space rocks caught in the act of near-Earth flybys.

Near-Earth Astroids PHAs 6FEB2009

Potentially Hazardous Asteroids (PHAs) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones all the time.
http://spaceweather.com/

On February 6, 2009 there were 1022 potentially hazardous asteroids.
Feb. 2009 Earth-asteroid encounters:
Asteroid//Date(UT)//Miss Distance//Mag.//Size
2009 BK58//Feb. 2 //1.7 LD//17//30 m
2009 BW2//Feb. 5 //8.4 LD//20//40 m
2009 BE58//Feb. 10 //8.6 LD//16//225 m
2006 AS2 //Feb. 10//9.2 LD//15//370 m
2009 BL58 //Feb. 11//4.8 LD//17//55 m
1999 AQ10 //Feb. 18//4.4 LD//13//390 m

Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach.
