Aucafidus is a trojan planet located on L4 point of Subralis (HD 28185 d, the name literally means "heaven"). Both Aucafidus and Subralis orbits a main sequence star HD 28185 (also known as HIP 20723 or SAO 149631), or locally known as Bicuxs or Biculus.

The planet has exceptionally large iron-nickel core, comprising almost half of the planet's volume, and thus sufficiently strong magnetic field. Due to this large core, Aucafidus is slightly more massive than Earth, and its overal density is much higher, resulting in higher surface gravity, despite being smaller than Earth.

Aucafidus is inhabited by 25 billion physical thinking beings, spread among roughly 2 million cities on southern continents, occupying about 20% of the entire surface of Aucafidus.

The surface is highly earth-like, with higher surface gravity, at 12.43 m/s2, and higher atmospheric pressure, almost twice than that of Earth.

Aucafidus does not possess any natural satellite.
