Meteo · Comet · Asteroid etc. What kinds are there in "stone" drifting in the universe and where do you come from?

A movie that answers simple questions of what kinds of "stones" such as Meteor · Meteorite · Comet · Asteroids the Greenwich Observatory drifts in space and where they come from where "Space Rocks"Is released to the public.

Space Rocks


The solar system with the Earth is very vast and various celestial bodies exist.


Between Mars and Jupiter there is an area where the orbits of asteroids called "asteroid belt" are concentrated.


Here, small stones and metal clumps that could not become planets are held by Jupiter's powerful gravity.


Asteroid (asteroid) exists in this asteroid belt. Since the area of ​​this asteroid belt is very narrow ......


There are also many cases where asteroids collide with each other and the orbit changes greatly. Asteroids whose orbit has changed have flew around the solar system.


In addition to the asteroid belt, there are many asteroids in the universe, but there are various designations for these.


A huge stone is called an asteroid ......


Small ones are called meteoroids (meteoroid bodies).


Furthermore, what has entered the Earth's atmosphere ... ...


We call it Meteorite.


There are some meteorites that burn out in the atmosphere and others that are not so ....


We call Meteorite (meteorite) what keeps the prototype without burning out even if it falls to the earth.


This meteorite often contains high density iron ... ...


The color is black and it is magnetized.


Such a meteorite is as old as the solar system, so it may be called the oldest thing among human beings touched.


The story changes, this time about comet (comet). There is a snow line (freezing line) by Jupiter which is a giant gas planet ... ....


There are a lot of ice-containing substances here.


Also, Saturn, Uranus and Neptune are also huge gas planets, around which there are ice rings "Kuiper belt" with large and small objects containing ice.


Pluto exists in this Kuiper belt.


A huge celestial group than the Kuiper belt which contains a large amount of ice which was made in the ancient times long ago is "Oulto cloud." The main component of the celestial bodies here is also thought to be ice, that is, ice is present in various places in the universe.



And when these ice - containing substances collide and change orbit, it becomes comet (comet).


This comet flies towards the sun ... ...


Sometimes you strike another object ... ...


"Tempo" which is a temporary atmosphere, and a tail which the substance of the coma leaked are caused.


It will disappear if it fell directly to the sun, but ... ....


There seems to be a thing that goes back in the direction which flew without falling to the sun.


The appearance of this comet can also be seen from the earth.



Also, when the comet crumbled down near the sun ... ...



Sometimes these fragments rush into the Earth 's atmosphere.


In addition, comets can burn out in the atmosphere and change into a meteorite.


There is a possibility that comets and asteroids are going to fall on the Earth, but thousands of comets & asteroids are falling on the early Earth.


This caused water to be born to the earth.


In other words, this comet played an important role to nurture the life of the earth.


Rosetta, also known as the "spacecraft landing on a comet" for the first time in history, continues to explore the origin of the solar system.
