Kepler-30, a three-planetary system located 10,000 light-years from us, shares a striking resemblance to our Solar System.
In a study recently published in the scientific journal Nature, scientists say they have discovered the first star system in which all the planets lie on the same orbital plane as our solar system.
Moreover, at the center of this system lies Kepler-30, a star as bright and large as the Sun.

The Solar System is a truly unique star system, with the orbits of all eight planets forming elliptical paths arranged on a flat disk, in sync with the Sun's rotation.
Even though humanity has discovered more than 5,000 exoplanets – meaning a huge number of star systems they belong to – we have never seen "brother" planets orbiting on the same disk like this.
To discover this unique system, a research team from the Massachusetts Institute of Technology, the University of California at Santa Cruz (USA), and other organizations analyzed data from NASA's Kepler space telescope, a device that tracks up to 150,000 stars.
To search for Kepler-30's planets and determine their orbits, they tracked dark spots appearing on the star's surface, as well as sunspot-like structures on this world .
From the data points, the authors concluded that Kepler-30 rotates along an axis perpendicular to the orbital plane of the largest planet.
Researchers then determine the orbital alignment of the planets by studying the gravitational effects of one planet on another.
By analyzing the planets' time variations as they passed the star, the research team derived their corresponding orbital configurations and discovered that all three planets aligned along the same plane.
This harmony gives the system a unique stability, much like our solar system, where the planets have been peacefully harmonizing for billions of years.
Associate Professor James Lloyd, from Cornell University, who was not involved in the study, commented that the new findings could shed light on how life evolved in the universe.
For a planet to have a stable climate suitable for life, it needs to be in a stable orbit. Therefore, the prevalence of star systems similar to our Solar System also helps us understand how common life is in the universe.
