10 fun facts about meteors would tell about the information that only a few people knew! Meteor is a rocky and metallic body in the outer space.
Facts about Meteors 1: Composition of Meteors
Most of meteoroids contain extraterrestrial nickel and iron. They have three main classifications: iron, stone, and stony-iron. The composition of meteoroids can be inferred as they pass through the earth’s atmosphere from their trajectories and the light spectra of the resulting meteor. From these trajectory measurements, meteoroids have been found to have many different orbits, some clustering in streams often associated with a parent comet, others apparently sporadic.
Facts about Meteors 2: Meteoroids in the Solar System
Meteoroids mostly derive from the asteroid belt, having been perturbed by the gravitational effect of planets, yet others are particles from comets, giving rise to meteor showers.
Facts about Meteors 3: Collision of Meteoroids with Earth’s Atmosphere
When meteoroids intersect with earth’s atmosphere at night, they are likely to become visible as meteors. It is called meteorites, once the meteoroids survive to reach the earth’s surface. Meteorites are transformed in structure and chemistry by the heat of entry and force of impact.
Facts about Meteors 4: Meteors
Public think that a meteor is a shooting star or falling star. It is the visible passage of a glowing meteoroid, micrometeoroid, comet or asteroid through earth’s atmosphere, after being heated to incandescence by collisions air molecules in the upper atmosphere, creating a streak of light through its rapid motion and sometimes also by shedding glowing material in its wake.
Facts about Meteors 5: The History of Meteors
In fact, Meteors were not known to be an astronomical phenomenon until the beginning of the nineteenth century although they have recognised since ancient times.
Denison Olmsted, an astronomer, after he made intensive research, he concluded that meteors have a cosmic origin. In addition, Giovani Schiaparelli’s success in connecting the leonids (as they are now called) with comet Tempel-Tuttle, the cosmic origin of meteors was now firmly established.
Facts about Meteors 6: Fireball
Fireball is a meteor brighter than any planets. Some other people believe that fireball is a meteor that would have a magnitude of -3 or brighter if seen at zenith.
Facts about Meteors 7: The Effect of Meteors on Atmosphere
The entry of meteoroids into Earth’s atmosphere produces three main effects: ionisation of atmospheric molecules, dust that the meteoroid sheds, and the sound of passage.
Facts about Meteors 8: The Colours of Meteors
The colours of meteors are caused by the relative influence of the metallic content of the meteoroid versus the superheated air plasma. The colours of meteors are including orange-yellow, yellow, blue-green, violet, and red.
Facts about Meteors 9: Acoustic Manifestation
The sound generated by a meteor in the upper atmosphere, such as a sonic boom, typically arrives many seconds after the visual light from a meteor disappears. Occasionally, as with the Leonid meteor shower of 2001, crackling, swishing, or hissing sounds have been reported, occurring at the same isntant as a meteor flare.
Facts about Meteors 10: Meteor Shower
A meteor shower happens because of an interaction between a planet.
