<![CDATA[ "TIC 120362137 is currently the most compact known 3+1-type quadruple star system." ]]>
A quadruple star system consists of four stars that are gravitationally bound to each other. These systems can provide insights into stellar formation and evolution, and their dynamics can be complex due to the interactions between the stars.
Compact star systems are characterized by their close proximity of stars, often leading to unique gravitational interactions and phenomena. These systems can challenge our understanding of stellar dynamics and the limits of star formation.
