Dar System

Dar System is an isolated, unusual binary system of a red dwarf called Dar A and a stellar black hole called Dar B. It is located on the outskirts of the Silky Way Galaxy. Not many civilizations know about it and none have yet permanently settled here.
== Formation and Evolution ==
Althougt not seeming like it at the first glance, the Dar System has a very complex and intricate history.About 600 mya, in a stellar nursery near the Silky Way's edge a stellar system has started to form. Eventually two stars formed: a big O-type star (Dar B) and its smaller companion M-type star (Dar A). Dar A most likely formed about 1-2 million years later, from the mass surrounding Dar B. 
Dar A formed closer to Dar B, than it is today. Before migrating away from B, it acquired a protoplanetary disk from the mass still surrounding Dar B. After 3 Ma only one planet formed from the disk, and it was Dar Ac along with its moon.
5 Ma after its formation, the O-type star turned into a red supergiant. It was becoming more and more unstable. 5 Ma later it exploded in a type II supernova. The explosion left behind a stellar black hole and a supernova remnant, which now is gone, but is described in many ancient texts of different civilizations across the Silky Way.
The explosion created alot of heavier elements and scattered them across all of the system. 
Millions of years later, Dar A and the black hole Dar B started to accrete matter from the explosion and that's how Dar A's asteroid belt, different minor planets, Dar Ab, Dar Bb and one other Dar B's planet formed.
Sometime in the near past, the unnamed Dar B's planet got ripped apart by its parent.
== Objects ==
=== Stars ===
The Dar System is a binary system of a red dwarf and a black hole separated by about 9.5 astronomical units.
*Dar A - A young red dwarf star. It is quite big for a star its type. It measures around 280 000 km in diameter. It has a mass of 82 jupiter masses and like many other red dwarfs, is also a flare star. It has a surface temperature of 3000 Kelvin.
*Dar B - A stellar black hole. It was once a B-type star that 1 million years ago exploded in a type II supernova. It has a mass of 10 solar masses, a radius of 30 km and a surface temperature of 0.000000000616871 K. It's only 1 million years old. It was once a B-type star which exploded in a supernova explosion. A dust belt is orbiting Dar B and it's the only way you can see it.
=== Planets ===
There are 3 major planets in the Dar system. There is also an abundance of small minor planets orbiting the stars. Biggest of which is DarA (1).

Dar Bb	 	 	
Dar B 	 	 	
Dar Ab - Freezing TwilightBrief DescriptionThe first planet from Dar A and smallest planet in the entirety of the Dar system. Has no moons. Very thin atmosphere.
Dar Ac - Ringed Terrestrial GiantBrief DescriptionThe largest planet in the Dar system. Has 1 moon. Very thin atmosphere. A ring system which is a relic of a captured asteroid that got ripped apart.
Dar Bb - Doomed Planet
Brief DescriptionThe only planet of Dar B. An icy blanet. A very thick atmosphere. No moons. Eternal night reigns there. It is doomed to get ripped apart by its parent.
=== Small Bodies ===
As stated before, there are many of small bodies in the Dar System. The most notable of which are:
- DarA (1): The largest object within the belt of Dar A.
- DarA (5): A trinary asteroid system of bodies relatively the same size (A: 220 km, B: 210 km, C: 130 km) located in Dar A's belt.
- DarAB (2): An unusual large object located far out, orbiting the barycenter of the system. (Essentially orbiting Dar B, because of its mass.)
- Many other...
=== Debris Disks ===
There are two belts orbiting each star in the system. The one orbiting Dar A is an asteroid belt and the one orbiting Dar B is a debris disk, which is a remnant of a destroyed planet.
The largest object in Dar A's belt is the minor planet DarA (1), which is 479 km in diameter, while the largest orbiting within Dar B's disk is a small body approximately 10 km in diameter called DarB (4).
== Exploration ==
The Dar System is very inhospitable and thus hasn't been visited by many civilizations. The most known explorer of the Dar System is the Verdan Federation, which so far has visited all 3 major planets in the system.
== Location ==
Dar System is located in The Silky Way, almost outside the ring of it. It is a quite isolated system. The nearest system to it is 100 light years away, which is the lonely, Y-class brown dwarf Apomonom.
== Future ==
In the next few million years, Dar B will rip apart its planet, due to it passing its roche limit. Then in 3 trillion years Dar A will turn into a blue dwarf, to then transform into a white dwarf. In a very long time Dar A will eventually cool down and turn into a black dwarf, and eventually Iron Star. In the far, far, far future, Dar B will decay via hawking radiation.
== Trivia ==
-The Dar System is based off a real system called GRO J0422+32
