3^rd Trumpet:  And the third angel sounded the blast of a trumpet; and there fell down from the air of the sky, a great and mighty star, as stretching across the sky of heaven, burning as set on fire, as if it were a lamp or torch and it fell down upon the third part of the streams and rivers and upon the fountains, that is, the supply of waters; And the name and character of the star is called Wormwood or a calamity of bitterness; and the third part of the rainy waters became wormwood or a calamity of bitterness; and an abundant and a great many human beings began to die off, because of the rainy waters, because they were made bitter. [Revelation 8:10-11].

Phase Three:  6^th Seal, 3^rd Trumpet, 3^rd Vial

[Rev. 6:13] And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.

[Rev. 8:10-11] And the third angel sounded, and there fell a great star from heaven, burning as it were a lamp, and it fell upon the third part of the rivers, and upon the fountains of waters; And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter.

[Rev. 16:4] And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood.

The “stars” and “a great star” and “Wormwood” is a comet, which will hit the earth’s atmosphere and melts completely before reaching the earth’s surface. Embedded within the frozen mass of gasses that form the comet’s nucleus, there are thousands, perhaps millions of tiny pieces of meteoric rock. These rocks will not melt like the frozen gases; instead, they will appear as “falling stars”“third” of the “rivers and upon the fountains of waters”among the continental land masses. that burn themselves out in the earth’s atmosphere. The entrance of the comet into the earth’s atmosphere will be heralded as a meteor storm and its final effect will be the poisoning of much of the earth’s water supply as the dense fog like gases descend upon the rivers and lakes within the continental land masses. It is most likely; this comet will fall upon the Eurasia continent, as it would fit the “third”of the “rivers and upon the fountains of waters” among the continental land masses. 

The current official definition of a meteoroid from the International Astronomical Union is "a solid object moving in interplanetary space, of a size considerably smaller than an asteroid and considerably larger than an atom".^[1][2] Beech & Steel writing in Quarterly Journal of the Royal Astronomical Society proposed a new definition where a meteoroid is between 100 µm and 10 m across.^[3] The NEO definition includes larger objects, up to 50 m in diameter, in this category. Very small meteoroids are known as micrometeoroids (see also interplanetary dust).

The composition of meteoroids can be determined as they pass through Earth's atmosphere from their trajectories and the light spectra of the resulting meteor. Their effects on radio signals also give information, especially useful for daytime meteors which are otherwise very difficult to observe. From these trajectory measurements, meteoroids have been found to have many different orbits, some clustering in streams (see Meteor showers) often associated with a parent comet, others apparently sporadic. Debris from meteoroid streams may eventually be scattered into other orbits. The light spectra, combined with trajectory and light curve measurements, have yielded various compositions and densities, ranging from fragile snowball-like objects with density about a quarter that of ice,^[4] to nickel-iron rich dense rocks.

Meteoroids travel around the Sun in a variety of orbits and at various velocities. The fastest ones move at about 26 miles per second (42 kilometers per second) through space in the vicinity of Earth's orbit. The Earth travels at about 18 miles per second (29 kilometers per second). Thus, when meteoroids meet the Earth's atmosphere head-on (which would only occur if the meteors were in a retrograde orbit), the combined speed may reach about 44 miles per second (71 kilometers per second).

A meteor is the visible streak of light that occurs when a meteoroid enters the Earth's atmosphere. Meteors typically occur in the mesosphere, and most range in altitude from 75 km to 100 km.^[5] Millions of meteors occur in the Earth's atmosphere every day. Most meteoroids that cause meteors are about the size of a pebble. They become visible between about 40 and 75 miles (65 and 120 kilometers) above the Earth. They disintegrate at altitudes of 30 to 60 miles (50 to 95 kilometers). Meteors have roughly a fifty percent chance of a daylight (or near daylight) collision with the Earth as the Earth orbits in the direction of roughly west at noon. Most meteors are, however, observed at night as low light conditions allow fainter meteors to be observed.

For bodies with a size scale larger than the atmospheric mean free path (10 cm to several metres) the visibility is due to the atmospheric ram pressure (not friction) that heats the meteoroid so that it glows and creates a shining trail of gases and melted meteoroid particles. The gases include vaporized meteoroid material and atmospheric gases that heat up when the meteoroid passes through the atmosphere. Most meteors glow for about a second. A relatively small percentage of meteoroids hit the Earth's atmosphere and then pass out again: these are termed Earth-grazing fireballs (for example The Great Daylight 1972 Fireball).

Meteors may occur in showers, which arise when the Earth passes through a trail of debris left by a comet, or as "random" or "sporadic" meteors, not associated with a specific single cause. A number of specific meteors have been observed, largely by members of the public and largely by accident, but with enough detail that orbits of the incoming meteors or meteorites have been calculated. All of them came from orbits from the vicinity of the asteroid belt.^[6]
