Kneva Sulchin is a binary star system, the primary star is Kneva. Kneva is a K0V Orange Main Sequence star, radius of 5.73 x 105 km (0.82 of Sol), mass of 1.22 x 1030 kg (0.61 of Sol), temperature of 4900 K, and luminosity of 1.35 x 1026 W (0.35 of Sol). The companion star, Sulchin, is an M7V Red Dwarf orbiting 3.82 x 107 km (0.26 AU) with a radius of 2.68 x 105 km (0.38 of Sol), mass of 5.3 x 1029 kg (0.27 of Sol), temperature of 2400 K, and a luminosity of 1.69 x 1024 W (Less than 1% of Sol).

Kneva Prime
| Class: | J |
| Distance: | 0.82 AU |
| Period: | 287.5 Days |
| Radius: | 66,276.55 km |
| Gravity: | 1.09 G |
Close enough to Kneva & Sulchin that the atmosphere is more turbulent than the average Class J planet. There is an extensive system of rings composed of frozen hydrocarbons and ice along with 15 small asteroidal moons. Gravitational forces pull planetary gasses from the planet to Kneva at a relatively slow rate, eventually it will loose all of it's atmosphere and become a Class X world in a few billion years. This planet also has an unusually low gravity, for reasons unknown. It is possible that it's compositional mass contains unusual compounds at the core, though no unusual readings (other than the lower gravitational field) have been detected.
Asteroid Belt
At a distance of 2.66 AU (mean) there is an extensive asteroid belt approximately 1.2 AU's in depth. The field is possibly the result of a planetary collision, there is sufficient mass to account for perhaps 2 planets though it could also be the result of a failed planet formation. Asteroids are primarily composed of Iron, Aluminium, Silver, and Lead.
Kneva 2
| Class: | J |
| Distance: | 5.24 AU |
| Period: | 12.79 Years |
| Radius: | 63,847.55 km |
| Gravity: | 12.48 G |
A standard Class J planet with an extensive system of moons, 27 smaller asteroidal moons and 11 larger moons though the largest is only 685.2 km in radius. All but 2 of the larger moons are Class D2, the other 2 being Class A2 (529 km radius) and Class B2 (685 km radius). Asteroidal moons match composition of those in the asteroid belt, making them likely captures of stray objects from the belt.
Kneva 3
| Class: | I |
| Distance: | 19.39 AU |
| Period: | 91.07 Years |
| Radius: | 28,625 km |
| Gravity: | 10.05 G |
This planet is composed as one would expect for a Class I world, hydrogen-helium atmosphere transitioning to methane, ammonia, and water near the small core. It has a system of 11 asteroidal moons with a single larger (Class C2 with 829.65 km radius) moon in orbit.
Kneva 4
| Class: | I |
| Distance: | 34.56 AU |
| Period: | 216.63 Years |
| Radius: | 24,551.40 km |
| Gravity: | 1 G |
Peculiar for even a smaller Class I world, this world has Earth-normal gravity due to an unusually small rocky core. While it's atmospheric composition places it firmly in Class I the lower gravity make it an oddity. There is a system of 5 asteroidal moons, all of which very close to the upper atmosphere and 5 larger moons as well. All of the larger moons are relatively unremarkable, each being class D2 with higher than average concentrations of ice but otherwise not noteworthy. The planet itself has one other unusual characteristic, the asteroidal moons have a composition that does not match those within the asteroid belt and likely were captured when the system passed near an extra-solar asteroid field. These moons have a high concentration of rare-earth metals such as neodymium and iridium.
