Solar system 'PDE247' is a dual star system that comprises the stars 'PDE247.A' and 'PDE247.B' and the retinue of celestial objects gravitationally bound to them: 5 planets and their 468 moons, as well as asteroids, meteoroids, planetoids, comets, and interplanetary dust.

The principal components of this star system are the stars 'PDE247.A' and 'PDE247.B' that dominate it gravitationally. 'PDE247.A' is a red giant class star that contains about 74% of the system's known mass, 'PDE247.B' is a red giant class star that contains about 25% of the system's known mass.

System 'PDE247' is located more than 3295 lightyears from the center of the galaxy.
