Sol System

The Sol System is a large system in the Sol Sector in the Orion Arm, which is home to Earth and the UFHW.

System components
The components of the system are shown on this list below, along with their orbital distances (in AU).
 * Sol
 * Mercury (0.38 AU) - a small terrestrial planet with a limited atmosphere, orbiting so close to its sun, that temperatures rise up to over 700 K (420oC). In 4.5 billion years, Mercury should get vaporized by the red giant Sol.
 * Venus (0.72 AU) - a medium sized terrestrial world with an extremely strong greenhouse effect, causing the temperatures to rise up to 750 K (475oC). Human theories prove that the planet used to support oceans and possibly even life, until the planet&apos;s large volcanoes erupted, releasing vast amounts of carbon dioxide into the planet&apos;s atmosphere.
 * Earth (1 AU) - another medium sized terrestrial planet with a dense atmosphere with lots of oxygen. The powerful atmosphere modifies the planet&apos;s temperatures to 290 K (15oC) and supports various forms of life, including the Humans, one of the Galaxy&apos;s most prominent species. Its powerful magnetic field protects the planet from ultraviolet radiation, which would harm most forms of life if the magnetic field never existed in the first place.
 * Luna - Earth&apos;s moon. A dry, airless ball of rock which does not have a potential atmosphere. It&apos;s major cities are protected by large domes of thick glass.
 * Mars (1.52 AU) - a small terrestrial planet, with an oxygen-rich atmosphere. Here, temperatures average at 278 K (5oC). It was the target of a major terraforming project lasting from 2339 to 2552.
 * Asteroid belt
 * Ceres (2.7 AU)
 * Jupiter (5.2 AU) - the largest gas giant in the system, having a diameter of over 140,000 km (88,000 miles) and many moons. Its lethal radiation and annoying gravity well proves impossible to escape. Miles beneath its clouds, hydrogen becomes a liquid, then under more pressure, a liquid metal.
 * Io - colloquially labelled as the Sol System&apos;s pizza moon.
 * Europa - Europa is mined by the Solar Mining Agency for oxygen and various other chemicals. It has a subsurface ocean, over 100 km (62 miles) deep, with jellyfish-like life forms.
 * Ganymede - the largest moon in the Sol System.
 * Callisto - an inactive, dark moon.
 * Saturn (9.58 AU) - famous for its huge ring system, Saturn proved too far out of the Sol System to be colonized. It is mined for helium-3, having the second largest supply of the isotope in the Sol System after Uranus. It is also a liquid planet like Jupiter, but its low density prove that it can float on water.
 * Titan - the only moon in the Sol System, with a potential atmosphere.
 * Uranus (19.2 AU) - having an axial tilt of almost 98 degrees, Uranus has a strange rotation and an even stranger internal composition. Uranus is an ice giant, with a thick atmosphere, which becomes a dense sea of liquid chemicals, including water, ammonia and methane once the pressure becomes critical. The helium-3 supply of Uranus is massive: Uranus is the largest producer of helium-3 in the Orion Arm. The supply of the isotope originates somewhere near its core.
 * Neptune (31.1 AU) - Neptune is another ice giant, but with much less hel-3.
 * Kuiper belt
 * Pluto (30-49 AU) - Pluto is the furthest known object in the Sol System which is inhabited by the public. Its elongated orbit modifies temperatures at an unprecedented rate: 55 K (-218oC) in the summer and a chilly 33 K (-240oC) in winter. In fact, it would take you less than a second to freeze over on Pluto without a spacesuit. The air is made of nitrogen, which is a liquid and a gas in the summer and a form of snow in the winter.
 * Charon - a moon which forms a binary system with Pluto.
 * Nix
 * Hydra
 * Haumea (43.13 AU) - Haumea is a very strange object. Its rotation rate is about four hours, meaning that the planetoid is extremely flattened, like an ellipsoid.
 * Hi&apos;iaka
 * Namaka
 * Makemake (45.79 AU)
 * Eris (68 AU)
 * Dysnomia
 * Oort Cloud
 * Sedna (518 AU)
