A meteoroid is a smaller type of celestial body in space. Abbreviated sentence: A meteoroid is a celestial body.
The abbreviated sentence is to shorten the long sentence of "thick branches and leaves" to a short sentence that only leaves the "trunk", and cannot change the main meaning of the original sentence, that is, to remove the branches and reduce the leaves. Abbreviation can be understood as the meaning of summarizing the meaning of a sentence.
-
Under the abbreviation of sentence learning, how to accurately abbreviate the sentence!
-
This sentence can be abbreviated as: meteoroids are celestial bodies.
Just delete the complement "in space" and the adverbial "a lesser one".
-
Meteors are part of the celestial bodies.

Do you have the answer?

First of all, you better understand what to do. The more knowledge, the better. But not all knowledge can be used. Especially now that many people are short on time. There is not so much effort. The best drink to work on in the future can be used for learning.
First of all, I would like to introduce the knowledge of computers. I want to be able to match with a machine, astronomy. Needless to say, computer basics. Understand the system, understand the operation of the office This is basic, I personally recommend learning to understand the database, learning a programming language is good
Mechanically, you need to be able to draw. Understand the principles of machinery. The software used is CAD, etc. You can check out the relevant tutorials on the Internet.
Astronomy. I don't understand. Don't dare to talk nonsense...
There's a buddy who also likes programming. I have something to do in the machinery industry. Programmed to increase the output over there. I was treated very well in the factory! So support you! Hehe!

First of all, it is most important that you prepare well for the recruitment now, and go to high school.
Learning high school knowledge is the most important thing. If you want to develop in science and engineering, you must first learn mathematics, physics and chemistry in high school, and these subjects are the foundation no matter what science and engineering majors you study in college. If you are comfortable studying in high school, you can get in touch with some related knowledge for the future.
There are very few university or graduate students who do astronomy, and even fewer graduates who do astronomy. Machinery, to learn well: advanced mathematics, mechanical drawing, CAD computer drawing, theoretical mechanics, mechanics of materials, mechanical principles, mechanical design, mechanical manufacturing basics, hydraulic pneumatic transmission, interchangeability and tolerance fit, electrical and electronic technology, metal technology, mechanical engineering materials, mechanical engineering control, etc.
These are the main disciplines of machinery, and they are all related to each other. The most important disciplines of mechanics are drawing, mechanical principles, mechanical design, and mechanics. Computer: Let's take a look at computer basics, programming, C language, etc.
Learning these is a bit difficult for high school students who are already busy, so very few of them learn about college. After learning high school first, it is a matter of course to study later.

The most realistic, go crazy to make up for high school math, high school math and junior high school math can't be compared, you are proficient in high school math and then consider something else. I used to be like you, but I didn't do math well in high school, and I didn't get a score in science.
-
If you are a computer, you should know some programming software and some programming knowledge, and if it is a machine, you can learn to talk about mechanical drawings or parts drawings.
-
To study the universe, you study astrophysics in college. The universities with strong strengths in this discipline are: Peking University, Nanjing University, Lanzhou University, and University of Science and Technology of China. The above is for reference only.

Astronomical? Gotta go to liberal arts, right? Polytechnic universities are all architecture, right?
-
It is recommended that you go to an American university in the future.
Different meteors have different compositions, and some meteors are asteroid fragments, mainly made of rock. >>>More
Quasar is the abbreviation of stellar-like celestial bodies, also known as quasar-like bodies, burly or quasar-like radio sources, and together with pulsars, microwave background radiation and interstellar organic molecules, they are known as the "four major discoveries" of astronomy in the 60s of the 20th century. For a long time, it has always puzzled astronomers. >>>More

Small rocks and debris (and other cosmic remnants) in the universe can be called meteoroids. When a meteoroid falls into the planet's atmosphere, it burns through atmospheric friction (strictly speaking, an electronic transition), leaving a bright trail of light, which is what we see as a meteor. The Earth experiences meteor showers produced by cosmic remnants several times a year. >>>More
Fire meteor is a kind of high-speed celestial body, generally rarely seen, mainly composed of dust and ice in space, dense gas crystals, etc., the size difference is very large, divided into two kinds, one is outside the atmosphere (meteor): when the star is flying at high speed, it will be converted into an equal amount of anion and cation, that is, plasma, positive and negative ions will then impact into molecules, and repeat, so what you see is the phenomenon of discharge, because the ancients did not understand electricity, so it became a fire meteor, as for the sound, there is also inaudible, Because there is no air in space, there is no sound, and the color is related to the composition of the star, which belongs to the flame color reaction, such as high sodium content is yellow, etc.; The other is the atmosphere (meteorite): the star belongs to the meteorite category, and the atmosphere friction heat**, the color is the same as above, generally red and yellow are common, because the atmosphere can transmit sound, so there is a sound, similar to the roar of the wind, pure hand fighting, I hope you, study together, not differential, I am a physics teacher, encourage the spiritual ...... of the landlordIf you don't understand, you can continue to ask me.
