Astronomers report finding a rare “perfect solar system” where the planets in the system move in incredible synchronization with each other.
Scientists report the discovery of a “perfect solar system” that formed without violent collisions to form a group of planets of different sizes like our planet.
The solar system, called HD110067, is 100 light-years from Earth and includes six planets, all of the same size. It has not changed much since its formation 12 billion years ago.

These undisturbed conditions make them ideal for learning how these planets formed. Do these planets have life?
The birth of our solar system was a violent process. While the planets were forming, the collision of some stars caused orbital disturbances until the speed of rotation (rotation) of every planet in our solar system, including the orbit around the sun (revolution), which is not related to each other.
But in HD110067, the planets are not all the same size. But there is also simultaneous rotation. The orbit around the sun is perfectly proportional.
By the time the innermost planet has orbited the star 3 times, the second, third and fourth planets will have orbited the star almost twice, and when these three planets have orbited the star 4 times, the last two planets will have orbited exactly 3 times.
This orbit around the Sun is so precise that Dr. Raphael Locke of the University of Chicago and lead researcher HD110067 described it as a “perfect solar system.”
“It is ideal for studying how planets form,” he said. “This is because the solar system did not have a chaotic beginning like ours. It has not been disturbed since its birth.”
Dr Marina Lafarga-Magro from the University of Warwick said the solar system is beautiful and unique. “It was really exciting to see something no one had ever seen before.”
Over the past 30 years, astronomers have discovered thousands of star systems. But there is no suitable system to study this. How do planets form? By planets of similar size and undisturbed systems, it is considered a valuable treasure for astronomers. This is because it is much easier to compare and contrast planets. This will help to create a clear picture of how it was formed and how it developed?
The HD110067 system also contains bright stars that will make it easier to track signs of life in the atmospheres of planets in the system.
All six planets in this system are called “quasi-Neptune” planets, which are planets 2-3 times larger than Earth but smaller than Neptune, but astronomers still do not know the details, and this type of planet is very advanced.
They do not know. Are subplanets composed mostly of rock, gas, or water, or do they have the right conditions for life to occur?
Dr Locke said the discovery of the HD110067 system was a good opportunity. To find answers to these questions
“It may not take 10 years. We know these planets. We know where they are. We just need a little more time. But it will happen,” Dr. Locke said.
If after this observation the research team finds that Sub-Neptune can support life. It would dramatically increase the number of habitable planets. Consequently, this will increase the chances of discovering signs of life on planets other than Earth.
