KONTAN.CO.ID – This is the reason why the planets in the solar system orbit in the same plane. The planets in the solar system orbit the same planet in the same plane.
When you were in elementary school, you may have seen a complete model of the solar system with the orbits of each planet orbiting the sun. Although invisible, the planets in the solar system orbit in the same plane as other celestial bodies, such as the moon and asteroids.
But what is the reason these celestial bodies orbit in the same plane?
The beginning of the formation of the solar system
To answer that question, we need a time machine that goes back 4.5 billion years. Quote from BiologyThe solar system is a large rotating cloud of dust and gas.
Nader Hakipur, an astronomer at the University of Hawaii at Manoah, was quoted as saying Biology.
The massive cloud measures 12,000 astronomical units (AU), with 1 AU being the average distance between the earth and the sun, about 93 million miles (150 million km). The cloud became so large that even though it was only filled with dust and gas molecules, it began to collapse and shrink under its own mass, Hakihipur said.
As the swirling cloud of dust and gas began to crumble, the debris spread out evenly. The dough is like a pizza maker swirling in the air.
The dough rises when rolled, but becomes thinner and more even. This is a picture of what happened at the beginning of the solar system.
In the middle of the cloud, all the gas molecules are squeezed and heated, Hakihipur said. Under tremendous heat and pressure, hydrogen and helium atoms combine to form billions of nuclear reactions in the form of a baby star, the sun.
Over the next 50 million years, the sun will continue to grow, collecting gas and dust from its surroundings and emitting waves of heat and radiation.

As the sun rose, it shattered the empty space around it.
In such a lengthy process, a protoplanetary disk has been created that orbits the young star. The disk spanned hundreds of AU’s and was only a tenth of that distance. The protoplanetary disk rotates continuously for ten million years.
Sometimes they collide with each other and some of them even get stuck together. Over millions of years, these particles turn into millimeter-long grains, and then from grains to centimeters of gravel, the pebbles collide and stick together.
From there, most of the material on the protoplanetary disk stuck together to form larger objects. Some of these objects grow so large that gravity shapes them into planets, dwarf planets, and moons.
Other irregular objects such as asteroids, comets and some small moons are also formed.
The reason why the planets in the solar system orbit in the same plane
Once the formation of the solar system and the process of creating planets and other celestial bodies were known, the reasons for their orbits in the same plane were revealed. Basically, a planet or other celestial body orbits in the same plane, where it originated.
Even today, Earth, Mars, Jupiter, other planets or even asteroids are orbiting in their respective fields.
Although the eight planets and other celestial bodies in the solar system are of different sizes, they orbit at approximately the same speed.
