Solar System: Know how the planes of the planets of the solar system became one

Many processes in space seem normal, but their reasons are strange. Something similar has also been found with a process in our Solar System. All the planets revolving around our Sun have the same plane. The reason for this was being investigated for a long time. Behind this is the long process of formation of the solar system, from which the planets and other bodies of the solar system were formed. Astronomer Nader Hajihipour of the Manoa’s University of Hawai’i has explained it in detail by explaining the solar system formation process.

Hajihipor, while explaining the formation of the Solar System, told Live Science that what is the reason behind the planes of the Orbits of Planets being similar. In his interview, he said that the reason for the planets to revolve around the Sun in one plane had started 4.5 years ago. At that time, the size of the solar system was enormous. Then it was a swirling cloud of dust and gas.

This swirling cloud was 12 thousand times larger than the distance between the Earth and the Sun. Due to such a considerable size, it started shrinking under its own weight, with which the dust and clouds also started shrinking and taking a flattened shape. At the same time, the molecules in this latter centre also began to compress, and the Sun was formed under a tremendous temperature and pressure. After 50 million years, the Sun continued to grow and swallow the surrounding gas and dust.

Hajihipor said that during its growth, the Sun started ingesting the gas and dust around it. Along with it, started sending intense heat and radiation. Slowly the Sun cleared the surrounding area. While at the same time, the cloud was also shrinking due to which the disk surrounding the Sun was formed. Which was flattening as well as spreading.

Over time, this cloud of dust and gas turned into a completely flat structure called a protoplanetary disk. This disk started revolving around the Sun. This disk spanned hundreds of astronomical units (Earth-Sun distance). But still, its thickness was equal to one-tenth of that distance. The plane of this disc later became the plane of all the planets.

Millions of years later, the dust particles of the protoplanetary disk came together and formed one millimetre-long grain in the disk. Over time, these grains grew and became fragments of one centimetre long. Later this became regular-shaped gravitational bodies such as planets, dwarf planets, moons. While many irregularly shaped objects such as meteoroids and asteroids. Turned into a comet.

Due to all these processes, the protoplanetary disk and the plane of the planets formed after that. When the disk was utterly dusty. After that, even after the formation of objects of different sizes, the entire plane remained the same. According to Hajihipor, this was the reason that the 8 planets of the Solar System and the orbits of other bodies were about one.
