Scientists find ‘perfect solar system’, key to answering questions about how planets formed

Astronomers report finding A rare “perfect solar system” where the planets in the system move in incredible sync with each other.

Scientists report discovery A “perfect solar system” that formed without violent collisions to form a collection of planets of various sizes like our own.

The solar system, named HD110067, is 100 light years from Earth and has six planets, all of the same size. And they have hardly changed since their formation 12 billion years ago.

These undisturbed conditions make them ideal for learning how these planets formed. And do these planets have life?

The birth of our solar system was a violent process. while the planets were forming Some stars collide causing orbital disturbances until the speed of rotation (Rotation) of each 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 similar in size. But there is also a synchronous rotation. And the orbit around the sun is perfectly proportional.

By the time the innermost planet orbits the star 3 times, the second, third, and fourth planets will orbit the star approximately 2 times. And when these three planets have orbited the star 4 times, the last two planets will orbit exactly 3 times.

This orbit around the Sun is so precise that Dr. Rafael Luke of the University of Chicago Lead researcher described HD110067 as a “perfect solar system”.

He said: “It is ideal for studying how planets form. This is because the solar system did not have a chaotic beginning like ours. and has not been disturbed since 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 system that is appropriate for studying that. 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 the planets. This will help create a clear picture that How were they formed and how did they evolve?

The HD110067 system also has bright stars that will make it easier to track down signs of life in the atmospheres of planets in the system.

All 6 planets in this system are called “sub-Neptune” planets, which are planets that are 2-3 times larger than Earth but smaller than Neptune, but astronomers still don’t know the details. This type of planet is very

They don’t know. Are sub-Neptunes made mostly of rock, gas, or water, or do they have the right conditions for life to occur?

Dr. Luke 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. Luke said.

If after this observation of the research team it is found that Sub-Neptune can support life. It would greatly increase the number of habitable planets. and therefore This will increase the chances of detecting signs of life on planets other than Earth.
