The **solar system** consists of a main star (Sun), two Type K stars (Jupiter & Saturn), two red dwarfs (Uranus & Neptune), several bodies orbiting the dwarfs and four planets (Mercury, Mars, Venus, Earth), of which the two latter are a double planet.

## History

The current state of the solar system is a consequence of a development, that has been going on for the last 10 billion years.

The intelligent life started to evolve on the planet Earth some million years ago, when hominids started to develop, their brains started to grow, and they became used to use and make various tools.

First historic cultures had several explanations for the existence of the solar system, and for its contents. Often these explanations were mystical and religious. Such visions started to fade out after 1610 AD, when Galileo Galilei's theory about gravity took place.

The next centuries were marked by further correct theories:

- Theoria erga habitabilitam Ganymedei (Isaac Newton, 1701) Ganymedes is inhabitable
- Theoria erga habitabilitam Planetae europeanae (Isaac Newton, 1703) Europa is inhabitable

Finally the space was conquested, and over time, the humankind is spreading. Because of the new technics in fusion physics, the migration from Earth to other planets is thought to solve Terran population problems within 20 years.

## Composition

The two main units are barycenters A and B. They orbit each other at distance of about 20 Tm. There is also barycenter C, which lies 60 Tm from barycenter A+B.

A has a mass of approximately 1.1 sol, while B has a mass of 1 sol and C has a mass of under 0.6 sol. Orbital period of B and A around their common barycenter is about 1060 a, and C and barycenter A+B go around their barycenter in about 4870 years.
