Solar System's True Center Of Gravity Calculated



Scientists have identified the true center of gravity of the Solar System. According to this, the center of gravity of the solar system lies not in the sun's core but on its surface.

Have you ever thought about the center of gravity of our Solar System? Most of you will probably say that the center is the middle of The Sun, the core. But that's not true. Because the sun, unlike what we think, does not stand in a fixed position when it revolves around its axis. All planets, especially Jupiter, which is the largest planet in the solar system, have a slight gravitational pull on The Sun. The Sun therefore shows an oscillation as it rotates around itself.

A new study published in The Astrophysical Journal has managed to detect the true true center of the Solar System with a margin of error of 100 metres. While 100 meters may seem like a great distance when you think of it humanely, when you think of the solar system's billions of kilometers in diameter, you can call it a margin of error close to zero.


How was the center of the solar system detected?



As you know, the sun is the heaviest celestial body in the Solar System, and the rocky planets, gas giants or meteors in the system, can exert a very low gravitational pull on the Sun. However, in order to perform a precise measurement, the impact of all the celestial bodies that could apply gravity to The Sun had to be calculated one by one, which is exactly what was done in the research.


As we mentioned above, planets can exert a very low gravitational pull on The Sun. Therefore, the center of gravity of the Solar System is not far from the center of The Sun, and according to published research results, the center of gravity of the solar system is located on the surface of the Sun. Considering that the half diameter of the sun is 696 thousand kilometers, we can say that the planets deflect the center of gravity of the Solar System by 696 thousand kilometers.

Why is it important to detect the center of gravity of the solar system?



The next work by scientists, who are currently able to precisely measure the Solar System's center of gravity, will be to measure gravitational waves of supermassive black holes, or pulsars, thousands of light years away. So the methods used to detect the center of the Solar System will then be used to detect black holes.
