What is satellite, why, how, where? What is the profit of it?

in #science6 years ago

Astronomy was first used by Johannes Kepler, in 1610, to explain the moons surrounding Jupiter, which the Galaxite Galilei first saw, with his own built telescope.
The question is not coming, why satellite name is "satellite"? Let's answer. The satellite word is coming from Latin, which translates into "follow". The moon is surrounded by the Earth, the moon is a satellite. The earth is rotating around the sun, so the earth is also a satellite. The Sun is surrounded by the Milky Way galaxy, so the sun is also a satellite. These are natural satellites. However, to describe something like "Man-made machines are surrounded by the Earth," the term "satellite" was first used in theoretically, in 1936 and later in the scientifically, in 1957, when the then Soviet Union sent an artificial satellite for the first time in the history of human civilization. Surely I have heard of Sputnik-1. The following year, in 1958, America sent its first satellite, named Explorer-1.

What is the satellite mainly?

What's the matter? One thing I sent outside the Earth's atmosphere with a rocket, why is it not going to knock it out? Or, is not going to fall again in the world? Here is the beauty of science. Anything that draws another object towards itself, which we call a gravitational. And, if one of those objects is the earth, then the earth, which pulls another object, tells it gravity (that is, a special name of gravity gravity, where the earth contains). Because of this gravitational force, we and others in the solar system are constantly moving around the sun. So, outside the Earth's atmosphere, in this orbit, this attraction of the earth and the motion of the object can find out the balance between these two, if something is sent there at that speed, then it will rotate around the earth and surround it. Since there is no barrier between air or anything else, so it keeps on moving at that pace, continuing (the first form of Newton's motion).

Astranis's satellites are about the size of a mini-fridge, while traditional satellites are closer to the size of a bus.

I realized that they are rotating around the earth. There are thousands of such satellite revolving around. But, why is there no conflict between them? Clashes are not happening because they are traveling in different orbits and at different speeds, each and every one of them. After that, there is no conflict, no. So in February of 2009, there was a clash between two communications satellites, one in America, another Russian. But this is the only such incident ever so far.

Why?

I have sent thousands of money to send it. What is the profit It has been achieved, that means you are sitting on Facebook using the Internet, making fun of satellites, trolling, to ensure that you can spend your life a little easier. How does that? Do this by predicting weather forecasts, so that you are less concerned about weather, storms, storm surge, and hurricanes in your daily life. Then, assume that if lost somewhere due to unavoidable brain disorders, make sure that you can give others accurate information about your exact location. In order to make the satellite unnecessary with your friend on the phone, make sure to make it, and waste thousands of taka waste, to make it more easily and hassle-free. After the joke is done, then open a TV channel so that you can pass quality time without any trouble in Aramas, to arrange it. These are for you now. There are many more things that you do not really feel necessary in your eyes. For example, observe the sun, solar storms, meteorite, and other planetary satellites in the solar system. Observing the stars, planets and galaxies outside the solar system will help scientists to know more about our planet.

How many Types?

There are many types of satellites. However, the two most commonly used segments are Geostationary Satellites and Polar Orbiting Satellites. Geostationary satellites are those whose speeds are similar to the rotating speed of the Earth and travel eastward from the equator to the equator. As a result, they seem to be steadfast in relation to a certain position from the world, which is the reason for such naming. Originally information about radio, television, telephone, location of somebody (GPS - Global Positioning System) - This satellite is used for this type of communication.
Another is Polar Orbiting Satellite. As the name implies, its rotation is poll-to-poll, that is, to the north-south. As the Earth moves around the East and this satellite turns northwards along the north, so it never stays with any position in the world, but it sits round on different regions of the world at any given time. This type of satellite is used mainly to get ideas about the weather in different regions of the world. Its height is much lower than the geostationary satellite. Distance from the surface of Geostationary Satellite, which is about 20,000 kilometers, in polar satellite, this distance is only 850 km. As a result, it can more accurately scan the atmosphere and the Earth's surface and can give information about the weather more accurately.
