Solar system

The Solar system is the system of bodies centered around the Sun, also known as Sol. The system is also known as the Sol system or just Sol. The system is made up of a single star and eight major planetary bodies. It is located in the Orion Spur of the Milky Way. The system is connected by a single hyperlane to the Alpha Centauri system. 
The system is most notable for its third planet, Earth, the homeworld of Humanity. This makes Sol the homesystem of Humanity. The system has as such become a major galactic center ever since humans developed space travel. With a population ofover twenty billion, it is the second-most populated system in the galaxy, after the Pelanna system. A little over 40% of the system's population is concentrated on Earth. The remainder is spread out across colonised natural bodies: Mars, Venus and moons such as Luna or Europa. Around three percent of the system's population lives in interplanetary environments, with nearly half of that population living on Tannhäuser.
