This study examined the distribution of planets in multi-planetary exoplanetary systems to determine if there are factors that influence planetary arrangement. The researchers analyzed systems with 4 or more planets, applying the Titius-Bode relation to calculate slopes and intercepts for each system's semi-major axis versus planet rank plot. They found the systems clustered around a Titius-Bode a value of 0.04, indicating the relation can be applied flexibly to other systems beyond our solar system. However, our solar system did not show as strong a correlation, possibly due to Mercury's proximity to the Sun. Future work will incorporate more exoplanetary systems and data to further analyze planetary arrangement trends.
