Hi look at this beautiful Outer Space then where are we before we learn more Don't forget to like comment and subscribe to this Channel so that this channel can continue to grow in outer space there are millions of Galaxies and we are in one of those millions of galaxies The Galaxy we live in is called the Milky Way or Milky Way The Milky Way Galaxy consists of a collection of solar systems one of which is the solar system we live in each solar system has a large star as its center the large star is the sun so the sun is the center of the solar system yes the sun is called a star because it can emit its own light Hi the sun has a gravitational force so that other celestial objects revolve around the sun these celestial objects include planets asteroids satellites comments and meteoroids Let's discuss one by one the sun is not only the earth that has layers the sun also has you know The layers of the sun if sorted from the inside out include the sun's core photosphere chromosphere and corona Eh this is not the name of the coronavirus Yes different the sun's core has a very high temperature functions as a source of solar energy This energy is emitted by radiation photosphere in this area there are sunspots which are areas with a very strong magnetic field cold and darker than the surrounding chromosphere to Hi when a total solar eclipse occurs, the chromosphere will look like a red ring and another corner of the corona is the outermost layer that is grayish and looks like a crown. The corona will also be visible during a total solar eclipse. Next, we will discuss celestial objects that revolve around the sun, starting from the planet. Well, planets are not stars, so they cannot emit their own light, unlike the sun. There are eight planets in the solar system. Have you ever heard the song " Planet Nyari Kode Series"? If not, you can listen to it later because it can make it easier to remember. Okay, the first planet is Mercury. Mercury is the closest planet to the sun. Its size is very small. Next, Venus is the second planet from the sun. It is usually called the Morning Star or Evening Star. You can also call it the Evening Star. It is called that because Venus can be seen from Earth at dawn or dusk without using any tools at all. Venus is known as the hottest planet in the solar system, even though it is not as close as Mercury. Want to know why? Because inside the planet Venus there are many greenhouse gases, causing a very large greenhouse effect. Do you still remember the theory about the greenhouse effect? Besides, another unique thing about Venus is that the direction of its rotation is different from other planets. If other planets rotates from West to East Venus is the opposite from east to west then the earth is the only planet that can be inhabited by living things including us the earth has one natural satellite namely the moon the moon always follows wherever the earth is so sweet yes because that is the task of the satellites always follow the planet from outer space planet earth looks bluish that's why some say the earth is the blue planet the blue of the earth because it comes from the vastness of the waters on earth for example the sea or Ocean Mars Tholib Mars looks reddish so Mars is also called the red planet planet Mars has two natural satellites namely demos and phobos jupiter the largest planet in the solar system has the most satellites Saturn this planet looks very beautiful as if it has rings that's why it's called a ringed planet actually the rings come from chunks of ice and rocks that move around the planet Saturn is beautiful yes Uranus this planet is known as the coldest planet in the solar system Hi and there is one more planet Neptune which is the farthest or outermost planet because its location is the farthest from the sun its size is not much different from Uranus besides the planets that revolve around the sun there are also floating rocks that are very numerous located between the orbits of Mars and Jupiter the rock is called an asteroid because there are so many asteroids and have orbits like planets so asteroids are also called planetoids or dwarf planets this asteroid from a distance is like a belt that is why it is called the asteroid belt with the existence of this asteroid belt separates the planets into two groups namely inner planets and outer planets planets that are located before the asteroid are called inner planets such as Mercury Venus Earth and Mars while the planets that are located after the asteroid are called outer planets including starting from Jupiter Saturn Uranus and Neptune inner planets are much smaller than outer planets and the number of satellites of inner planets is very small some even do not have satellites other celestial bodies located in outer space are comets the characteristic of comets has a very oval trajectory different from the trajectory of planets that are elliptical comets are also called tailed stars the direction of the comet's tail is always away from the sun because of the very strong push from the wind and solar radiation there is one more celestial body that you must know the shape of the rock is also similar to an asteroid actually this celestial body comes from rock Asteroids that move closer and are attracted to the gravitational force of the earth this celestial body is called a meteor Kid because it is attracted by the gravity of the earth so it will fall to earth and rubbing against the earth's atmosphere, look like a shooting star, yes, the shooting star comes from a meteoroid, but its name is now Meteor. A meteor is a meteoroid that burns up because it rubs against the earth's atmosphere. If the size of the meteoroid from outer space is very large, it is possible that the meteor that rubs against the earth's atmosphere will not burn up and still leave rocks that reach the earth. Well, rocks that come from meteors are called meteorites, so meteorites are meteors that do not burn up. The power of Allah is so beautiful. God, the Almighty Creator. We must be very grateful because without His power, there would be no universe that is so vast and beautifully arranged. That's all for now. Let's wait for part 2.
