*** Asteroids - Meteoroids - Meteors - Meteorites - What are they, where do they come from and impact frequency ***
March 21 2013

Since there have been many discussions regarding these "space rocks", I wrote this article for GLP in order to give a small glimpse of the beautiful and dangerous (to us) cosmos that surrounds us.
Even though there is little we can do to avoid such threats, understanding may help to ease our minds.
Knowledge is power!

There are several classifications for these "space rocks", size, composition and off course trajectory is what we really need to know.

First lets make something clear, what you see in the sky as a streak of bright light and sparks is called a "Meteor", if the meteor reaches the ground it is called "meteorite.
Most meteors burn up in our atmosphere before reaching the surface, the consensus is that anything smaller than a large size car will burn up and leave nothing but dust.
Therefore any space rocks, that have reached our planet's surface and you see in pictures or are fortunate enough to find, are called meteorites.

Meteorites are classified in 3 main categories and several other sub-categories


Iron meteorites. (usually 90% iron and the rest Nickel and trace elements)

Meteor1

Stony-iron meteorites (A mixture of both iron and stone)
Meteor3

Stony meteorites (mostly stone, also called Chondrites)
Meteor2

Meteorites in space are called "Meteoroids" and are anywhere between a meter and up to 1km in diameter, anything bigger than 1km is called an asteroid. Asteroids can reach several hundred kilometers in diameter and are mostly grouped in the asteroid belt between Mars and Jupiter.
Once in a while 2 or more large/small asteroids will collide within the belt and some of the resulting fragments are flunked out of the belt's orbit and are then subjected to other celestial object's gravitational forces.

This is a graphical map of the asteroid belt.
belt1

Meteoroids can travel for countless miles and 100's of million of years. Some of them will collide with other celestial objects such as planets and moons. Keep in mind that this cosmic billiard game has been going on for billions of years therefore there are millions upon millions of meteoroids traveling in space at ten's of thousands of miles an hour.

This is a current map that shows all tracked objects in space near us.
It shows an upper view our solar system, the sun is in the center and the inner planets names and orbits are also shown, Mercury, Venus, Earth and Mars.
The green dots represent objects that will not come near Earth anytime soon. The yellow dots are objects that are approaching Earth but their orbits do not cross ours.
The red dots are objects that DO cross our planet's orbit and there are thousands of them.
The big white arrow points to Earth for easy identification.

neostorm

Astronomers estimates puts the number of civilization-ending sized asteroids in orbit within our solar system, at around 700,000 and we are only able to track a small fraction of them.


roid3

Impact Frequency.

At any given day there are 100's of meteoroids that collide with our atmosphere, most of them too small to be seen but once in a while a large one will put on quite the fireworks show, such as the one that exploded over Russia a few weeks ago.
Meteors that explode in midair are usually the stony types, friction from air molecules against the meteors surface , as it travels at 1000's of miles an hour, can reach 1000's of degrees and as the rock melts, gases are released which can cause sudden burst thus reducing a big rock in to smaller and mostly harmless bolides.
However, every once in a while (tens of millions of years) a KT-sized asteroid of 10km plus does hit our planet and that, my friends, would be a complete game changer.


Impact1

This article explains the intricacies of impact frequency in a more succinct manner.
[link to impact.arc.nasa.gov]

"Since the mid-1990s, the most common estimate has been that the Earth is hit by a "civilization threatening" impact (by a 1.5-km-diameter asteroid) about twice per million years, which is equivalent to a 1-in-5000 chance per century. But it is hard to tie down such estimates, in part because there is also a range of uncertainty as to what constitutes a civilization-threatening impact, spreading over at least a factor of two in asteroid size (from 1 km to 2 km diameter)."

the Alinda Family of asteroids

[link to en.wikipedia.org]

Some Alindas have perihelia very close to Earth's orbit, resulting in a series of close encounters at almost exactly four-year intervals, due to the 4:1 near resonance.

One consequence of this is that if an Alinda asteroid happens to be in an unfavorable position for viewing at the time of its close approach to Earth (for instance, at a small elongation from the Sun), then this situation can persist for decades. Indeed, as of 2010, the Alinda asteroid 1915 Quetzálcoatl had been observed only once since 1985.

Another consequence is that some of these asteroids make repeated relatively close approaches to Earth, making them good subjects for study by Earth-based radar. Examples are 4179 Toutatis and 6489 Golevka.

Indeed, there are several periodic groups of asteroids that come around in regular intervals.

They are objects that come from something called space (pronounced speys), and the frequency depends on how many times they hit earth.

Space rocks can be weaponized by simply changing the orbit so that it will impact earth, with fine tuning they can be aimed at specific targets.

Over 50% of the Russians believe that the United States did just that, with a force of many nuclear bombs.

How do they do it? Use a spaceship and tractor beam to change the asteroid orbit. For instance the USAF has an antigrav ship the TR-3B, its antigrav might work as a tow line in the asteroid belt.

Thread: 100% Proof The Military Has Alien TR-3B Craft to Travel Into Space

Natural weapons are better than nukes, nukes are hard to impossible to cover up, they are basically expensive weapons that are never used and must be decommissioned and recycled because the nuclear material degrades over time.

HAARP can steer hurricanes and demolish whole areas and cities, it is a wonderful weapon in the hands of Zionists practicing "creative destruction" as people have to spend money to fix the shit destroyed by the banksters.

Asteroids are slung inif by god's hand, with an asteroid and top secret space craft the minions of evil can have fun pulverizing earth.

the asteroid belt is thought to have once been a planet like Earth, that was smashed into a million pieces.

If a meteor the size of Texas hit the earth, our planet would be smashed into a million pieces. It has happened before.

good news is, we would all be dead before we knew anything had happened.

Fascinating assumption.
That notion has been theorized but off course unless we send a scientific mission to the belt we cannot prove it.

Technically it's considered an iron meteorite, but it looks more like the stony iron you have pictured there (just the way the crust looks). I purchased it at the NASA visitor center a few years ago. It's fairly small, fits in the palm of your hand, but it's not one of those tiny shavings of a meteorite they sometimes sell. It wasn't too expensive though, less than 20 bucks.
