Solar system 'VAD128' is a dual star system that comprises the stars 'VAD128.A' and 'VAD128.B' and the retinue of celestial objects gravitationally bound to them: 8 planets and their 726 moons, as well as asteroids, meteoroids, planetoids, comets, and interplanetary dust.

The principal components of this star system are the stars 'VAD128.A' and 'VAD128.B' that dominate it gravitationally. 'VAD128.A' is a yellow dwarf class star that contains about 99% of the system's known mass, 'VAD128.B' is a brown dwarf class star that contains about 0% of the system's known mass.

System 'VAD128' is located more than 2536 lightyears from the center of the galaxy.

VAD128.2, the second planet in this system, may feature life forms. Its average temperature is 337K (64C) and it's atmosphere contains 32% of oxygen. One year on VAD128.2 lasts 802 days, one day lasts 30 hours. It's diameter is 6618 km, 0.5 times the diameter of the Earth.
