The stars of the system, the white star and the yellow dwarf (spectral types A1 V and G2 V). Both stars are relatively close to each other, but because of the effects of stabilizers, they remain fairly stable in terms of activity.

Both suns rotate around their center of mass at a distance of 0.29 AU. from each other.

Currently, it is a small, hot planetoid with extremely inhospitable conditions for life. The "atmosphere" is a cloud of suspended dust and some gases.

Raos
- Orbit radius: 25.3 a.e.
- Orbital period: 51.99 years
- Planet radius: 8,100 km
- Number of satellites: 0
The fifth planet of the system is a relatively boring sight. It is a brownish planetoid almost without an atmosphere and without life, containing several unusually rich deposits of rare-earth minerals, which made planetside mining operations to be viable. Despite the fact that the planet was the last to form, it cooled down very quickly as it turned out to be deprived of heavy elements, which prevented it from issuing a full-fledged core and magnetosphere. Because of this, in spite of its size, gravity is quite low on it - 0.9 terrestrial.
Asteroids
- Orbit radius: 29-40 a.e.
- Orbital period: ---
- Radius: from 20 m to 400 km
An asteroid belt is located between Raos and Gaulurr, which does not represent anything extraordinary except for its density - the estimated total mass of the asteroid field could be 97% the mass of a planet the size of Harr.
Perhaps the belt was formed by itself, or it is the remains of a building material left by the Ancients.
Resources are being extracted in the belt, especially various rare-earth elements.
Gaulurr
- Orbit radius: 54 a.e.
- Orbital period: 162.11 years
- Planet radius: 106,400 km
- Number of satellites: 143 (8)
The largest and most massive planet in the system, by many also called the most beautiful. It has the largest number of satellites - 8 planetlike moons, and more than a hundred and forty trapped asteroids and comet nuclei, which are minor satellites. Its bright violet-purple color is caused by the composition of its atmosphere. Gaulurr is an extremely active planet, which has the most furious winds - the speed can easily reach thousands of kilometers per hour or more. The only gas giant in the system with a wide and highly visible ice ring. The planet contains numerous research probes and orbital stations, and an extensive network of industrial gas extractors, processing hephrene - a highly important gas for space travel, which powers hyperspace generators and reactors, and which provides the planet with its unique purple color. The gas deposits are truly colossal, with hephrene accounting for approximately 85% of Gaulurr's mass.

The humongous quantities of hephrene under such extreme conditions are a target of numerous scientific researches being conducted on the planet. This makes Harr one of the most important solar systems of the Alliance.
Hreot
- Orbit radius: 95.5 a.e.
- Orbital period: 381.25 years
- Planet radius: 64,800 km
- Number of satellites: 67 (5)
The smallest gas giant of the system, in size and properties most reminiscent of Jupiter.
Harot
- Orbit radius: 154 a.e.
- Orbital period: 780.71 years
- Planet radius: 84,300 km
- Number of satellites: 43 (4)
The most distant planet of the system and the second largest gas giant. It consists mainly of hydrogen, helium and methane, which gives the planet a rich blue color as a result.
Harot, both with Hreot, were considered a dim stars for a long time after their discovery, because of their extremely long orbital cycle (both planets have not managed to complete even two orbital turns since their discovery). The status of the planets was confirmed only after technology has progressed enough to allow a precise triangulation of the planet's distance.
