What are the four types of solar systems?


Science News Desk – Our solar system is unique. But earlier scientists used to think that all solar systems in the universe would be the same, but as information about new planetary systems came, they found that our solar system is somewhat unique. This has been confirmed by studies both from the University of Bern and the National Center of Competence in Research in Geneva, and from Planet, which have been published in the journal Astronomy & Astrophysics.

For the past several years, astronomers have been finding that in observations of planetary systems outside the Solar System, planets have similar sizes and weights to their neighbors. But it has not been possible to decide whether there are only two types of planetary system, one like ours or one in which all the planets are the same size. So the researchers devised a framework in which to determine the similarities or differences of planets within the same type of system, and in this effort they discovered four types of solar systems or planetary systems.

The researchers divided these into four classes: uniform, ordered, anti-ordered, or mixed, in systems of similar composition, the planets have similar masses to neighboring planets. In general, as planets move away from the Sun, their mass increases, as in our solar system. The weight of the planets in an irregular or anti-order decreases with distance, and the size of each planet in the compound varies greatly.

The researchers say that this type of profiling of the planetary system can be applied to other factors such as the radius, density, water content of the planets. But the question arises that what kind of structure (Structure of Planetary System) is seen a lot in the planetary systems. Which factors play a role in the formation of structure and which do not. Researchers say they may have some answers.
