What is the planetary system to ours?

The solar system is a collection of celestial bodies consisting of the sun and all the objects that revolve around it, while the universe is the place where the solar system is located, which is a single, infinite giant space. the only space that we know and know in the present moment of existence. We do not know the extent of the universe to where it ends. In fact, regarding the material for its formation and the process of how it was formed, it is still only a theory, meaning that it is not a certainty, that later the theory will collapse if there is a new theory finding. However, for now, the theory that is still used and valid is the Big Bang theory.

The solar system is one of the systems in the universe apart from other celestial bodies such as stars and planets, and others such as: comets, asteroids, moons (artificial satellites), space clouds, etc., as well as a system of laws such as gravity, black holes (black holes), and others, as well as a collection of clusters of celestial bodies that are formed such as the Solar System, Galaxies, and the Universe itself (Universe). There is even a recent theoretical finding, namely, that there is also a collection of Universes, or better known as the Multiverse. Here we will only discuss enough about the Solar System.

The solar system, as we already know, whether on television or textbooks, that it is a collection of celestial bodies consisting of a star (sun) as the center of its orbit and all the planets that surround it and also the moon (satellite) natural) that surrounds the planet as well because it is bound by the gravitational force or attraction of each. So far, there are eight known planets (of which there were originally 9, including the planet Pluto, but after various studies, Pluto is not part of the conditions for becoming something called a planet), also with five dwarf planets/ dwarfs, 173 natural satellites, and millions of other celestial bodies such as meteors, asteroids, comets, and others, both within the solar system itself, and those that pass through it.

The solar system has an arrangement consisting of the sun as the center of its orbit, 4 (four) inner planets, namely: Mercury, Venus, Earth and Mars, the Asteroid Belt, 4 (four) outer planets, namely: Jupiter, Saturn, Uranus and Neptune , Kuiper Belt, Scattered Disc, and Oort Cloud. Then, on every planet, including dwarf planets, some have natural satellites and some don't. For example, those that do not have natural satellites are the planets Mercury, Venus, and others, while the planets that do have natural satellites are as follows:

A. EARTH = 1 Natural Satellite named "Moon"

B. MARS = 2 Satellites

C. JUPITER = 79 Satellites

D. SATURN = 82 Satellites

E. URANUS = 27 Satellites

F. NEPTUN = 14 Satellites

• Orcus = 1 Satellites
• Pluto = 5 Satellites
• Salacia = 1 Satellite
• Haumea = 2 Satellites
• Quaoar = 1 Satellite
• Makemake = 1 Satellite
• Varda = 1 Satellite
• Gonggong = 1 Satellite
• Eris = Satellite

The solar system has planets that have different distances for each planet from the sun, namely:

1. MERCURY = 57,900,000 Km (Inner Planet)

2. VENUS = 108,000,000 Km (Inner Planet)

3. EARTH = 150,000,000 Km (Inner Planet)

4. MARS = 228,000,000 Km (Inner Planet)

• Ceres = 415,000,000 Km (Dwarf/Dwarf Planet)

5. JUPITER = 779,000,000 Km (Outer Planet)

6. SATURN = 1,430,000,000 Km (Outer Planet)

7. URANUS = 2,880,000,000 Km (Outer Planet)

8. NEPTUN = 4,500,000,000 Km (Outer Planet)

• Pluto = 5,906,000,000 Km (Dwarf/Dwarf Planet)
• Haumea = 6,450,000,000 Km (Dwarf/Dwarf Planet)
• Makemake = 6,850,000,000 Km (Dwarf/Dwarf Planet)
• Eris = 10,100,000,000 Km (Dwarf/Dwarf Planet)

We can briefly know the solar system in the following description, starting from the sun as the center of its orbit:

A. THE SUN

The sun is a local star, which is a giant ball of hot gas that comes from a burning of hydrogen gas with helium which has a composition of 3/4 is hydrogen gas and 1/4 is helium. The sun has a very large size, about more than 1.3 million earth volume and 333,420 times heavier than the earth. The gigantic pressure from the sun can turn the sun into atomic hydrogen power. The large expenditure of energy from the sun makes the temperature very hot, and can reach 15 million degrees Celsius. This extraordinary heat is able to turn the surface of the sun into a very hot hell.

The sun has a surface or better known as the photosphere which can emit heat of more than 5,500 degrees Celsius. The heat is enough to be able to melt almost all the elements that exist. The photosphere is covered with bright spots called granules, from which heat from the core erupts through the radiation zone and convection zone to the surface. Above the photosphere is the atmosphere of the sun, with the chromosphere below it and the corona above it. The very large flames are very hot hydrogen called "Solar Prominence" which can radiate to a distance of more than 100,000 kilometers.

The sun has rays and other forms that come from the radiation emitted by the sun giving us enough heat and light directly and also qualified energy for a process of photosynthesis in plants, as well as fuels such as petroleum and coal which are formed from organisms and plants small ones, which also get and store energy from the sun.

The sun has a cooler middle, there are also sunspots. These black spots are in a group and move across the surface of the sun. The number of these black spots varies and reaches a maximum every eleven years. Scientists believe that these black spots are related to cooling and changes in the weather on earth.

The sun at a certain time, when the earth and the moon as well as the sun are in one line, will cause a phenomenon called an "eclipse", this occurs because one of them loses light / is blocked from the sun. A lunar eclipse occurs when the moon moves behind the earth and forms a shadow. Meanwhile, a solar eclipse occurs when the moon is between the sun and the earth, and this also produces a shadow a few kilometers wide from the earth. Other planets can also be blocked by the moon. From Earth, we can see the moon and also its shadow across the planet's surface.

The sun is a very large astronomical object, there are still many things that we cannot understand, including scientists about the sun. Therefore, in December 1995, NASA launched SOHO (the Solar and Heliospheric Observatory). SOHO is orbited towards the sun with a balance between the earth's gravitational pull and the sun's gravity. The SOHO periodically monitors and transmits information to earth via radio antennas. This has been going on for several years until now.

2. MERCURY

Mercury in Mariner 10's research on the planet Mercury found that Mercury is a very barren and dustiest planet. This planet is very little covered by the atmosphere, so there is nothing to protect it from meteor attacks. The surface of the planet Mercury is filled with holes, like those of our moon. This planet has a very extreme temperature, which is almost and has reached even exceeding 430 degrees Celsius, meaning that it is really, really, really hot, incredibly hot and burning, and sometimes it can also suddenly become minus up to -180 degrees Celsius (really very cold gripping), Anyone want to live in Mercury?

2. VENUS

Venus is the planet's closest neighbor to Earth, with a distance of about 42,000,000. Venus is surrounded by a very thick atmosphere composed of carbon dioxide (CO2) and other gases, as well as acidic sulfur. With the thick atmosphere on Venus, it is enough to put pressure on the surface of the planet 90 times greater than the atmospheric pressure on Earth where we live. The pressure is enough to destroy the house to the ground. The gas that surrounds Venus absorbs the sun's heat perfectly, so that Venus cannot escape from what is called the greenhouse effect. Venus' temperature is around 470 degrees Celsius (very hot or cold huh!), and makes it the hottest planet compared to other planets (don't you think about living there, besides Mercury). Venus is about the same size as our Earth, and has 4/5 the mass of Earth.

3. EARTH

Earth as we see it is our heaven for now, namely earth, aka home sweet home, which is the only planet that has life that we just found out about. Earth is one of the four planets that has the closest orbit to the sun. When viewed from outer space, Earth is the most amazing planet, because it has many changes that other planets don't have. For example, like white clouds that can change patterns, the blue color of the ocean, as well as the green and brown colors of a plain.

Earth as we already know, the earth is the only planet that has water, which is an absolute requirement for the formation of life. We also know that there is another planet that allows life to exist because it has water and an atmosphere, namely the planet Saturn. If so, do you want to live there? I'm afraid that later you'll end up living with micro-organisms anyway.. xixixixixi.

4. MARS

Mars is known as the red planet, because the red dust is enough to give the planet a rosy red effect, which covers its surface. The dust is made from the oxidation of iron, which in earth is known as rust (but not gold rust!). The Martian surface is marred by old holes, fissures, and volcanoes. On the planet Mars there is also the highest mountain in the solar system, namely Mount Olympus with a height of 25 km. Mars is one of the planets that has an atmosphere with temperatures during the day like those on earth. However, the atmosphere on Mars is very thin, so temperatures at night can reach minus -130 degrees Celsius (very cold). In research about this planet, it was concluded that only microscopic life can live on or under the surface and these organisms are in the water.

5. JUPITER

Jupiter is the largest planet in the solar system and has the combined weight of the other four planets. Jupiter rotates very fast, one rotation can take more than 10 hours on its imaginary line. Jupiter is mostly composed of hydrogen and helium gases which also have gravitational pressure, and these elements become liquid when they approach the core. Jupiter has a dense core, like a giant storm and is filled with a large red spot that is three times larger than Earth.

Jupiter has the most moons among the other planets in our solar system. About 400 years ago, Italian astronomer Galileo Galilei used a telescope to investigate Jupiter and found the moons around the planet, and the most dominant were the four largest moons discovered by Galileo, namely: Io, Ganymede, Europa, and Callisto.

6. SATURN

Saturn is about the same size as the planet Jupiter, and is made mostly of liquid and solid hydrogen and helium. The planet is surrounded by a halo ring of immense brightness, and is made up of billions of dust and ice no bigger than a tennis ball. The ring surrounds the planet Saturn without stopping.

7. URANUS

Uranus isn't as big as the planets Jupiter or Saturn, but it's still four times wider than Earth and 14 times as massive. Uranus is located very far from the sun, so this planet has a surface temperature of minus up to -210 degrees Celsius. Uranus circles the sun on almost every side, so each day and night is 42 years long

8. NEPTUN

Neptune is slightly smaller than the planet Uranus, and has about the same temperature as the planet Uranus. Neptune also has oceans of water, methane and ammonia thousands of kilometers deep around its rocky core. Above it, there is an atmosphere of hydrogen and helium gas with an average wind speed exceeding 2,000 km/hour. From a distance, on the blue surface of the planet, there are wisps of white clouds. Like Jupiter, Neptune also has a giant storm area, which is called the Great Dark Spot.

The solar system can be briefly concluded, that the solar system is only a small part of a system in our universe. It is estimated that there are still many other solar systems in this universe, not only thousands, maybe even billions of other solar systems that exist outside besides our own, if we look at the number of galaxies, the number of which is fantastic is incredible. what we already know, that the formation of galaxies is a collection of billions of stars (sun) or billions of solar systems that are in it. And the number of galaxies... wow... billions too. For that, we must be grateful to God the Creator, Who Has Created It All, and the life in it, namely humans, who are one of the creatures that inhabit and reside on a planet that has life, namely earth, the only planet of life in the solar system.
