Sun's Warmth Pushes Meteors Toward Earth

by Mitch Battros  (ECTV)

And you thought you were imagining things! The Reuters article below as reported by a consortium of scientist, suggest the NEAR (near earth asteroids) in other words, near misses, have increased due to the Sun, rather than cosmic collisions. Wow, if this holds true, it would give cause to the sharp increase we have witnessed in NEO's (near earth orbits) this year.

As most of you already know, we are at the apex of what NASA calls "Cycle 23". NASA claims we are at the highest point of a natural eleven year cycle. My research however, suggest we are in a much larger cycle that supersedes the known eleven, twenty two, and even twelve hundred year cycle. Many have called this a "Mega Cycle". What this could mean, according to this new press release finding, in relation to solar activity with increased asteroid/meteor NEO's, we are in for a hell of a ride.

I would suggest, rest assured, you are not imagining things. There indeed has been a sharp increase in celestial activity, which raises the possibility or (probability) of a collision with Earth. The question still stands, not if, but when, and now how big!. Let us all hope the rock that does come our way will be only meteors in size, and not kilometers.

LONDON (Reuters) - Scientists on Wednesday revealed the way meteorites reach the Earth, saying their paths were influenced more by the sun than cosmic collisions.

How meteorites, or asteroid fragments, come to collide with the Earth has been the subject of scientific debate for some 200 years. Previous theory held that asteroids, which exist in a belt between Mars and Jupiter, collided, ejecting meteorites into regions in the asteroid belt called orbital resonances. Within those regions the gravitational fields of Jupiter and Saturn acted on the meteorites, sending them into new paths that might intersect the Earth.

But Paolo Farinella, who died in March, and David Vokrouhlicky said in the journal Nature that differential warming and emission of heat by asteroid fragments in the asteroid belt caused them to drift into orbital resonances over time.

``Essentially, the 'afternoon' side of the rotating body (asteroid) is warmer than the 'morning' side, so the re-radiation of the Sun's heat produces a small net force across its path,'' Clark Chapman, of the Southwest Research Institute, Colorado, said in an accompanying article.

``The simple billiard-ball analogy of collisions between rocks knocking each other around the solar system does not stand up to elementary scrutiny,'' he added. ``It is no easier to 'bump'...objects...with finite material strengths than it is to hit eggs around the fairways with a golf club.''

Problems Of Age And Origin

Farinella, from the University of Trieste in Italy, and Vokrouhlicky, from the Charles University in Prague, say the heat differences -- so-called Yarkovsky forces -- explain problems of meteorite age and origin that have until now confounded scientists.

The collision model implies the swift ejection of an asteroid fragment into an Earth-bound trajectory and would result in relatively young meteorites. However analyzes of Earth meteorites have shown they are tens of millions of years old.

Yarkovsky forces cause a gradual drift into orbital resonances over tens of millions of years and explain why meteorites are so much older than the collision model would suggest. Collision theories would also imply that meteorites are derived from relatively few asteroids which are located near the orbital resonances.

However, studies of the make up of meteorites on Earth would be more understandable if meteorites came from asteroids located further from the orbital pathways, and not just from the few asteroids at the edges of the resonances.

The drift theory, which was validated by computer simulations, implies that meteorites can come from a larger pool of asteroids located both close to and far away from the orbital resonances.
