Historic system famous as both the birthplace of humanity and as the political capital of the Federation. A very expensive and prestigious system to live in and a popular tourist venue. Most rich humans will visit Earth once in their lives. All the major corporations have their headquarters on Mars, terraformed in 2286, which is the main centre for administration.

Sol is a single-star system in the Orion-Cygnus Arm of the Milky Way Galaxy . The terrestrial planet Earth is a popular tourist destination due to its historical value as the birthplace of humans . Terraformed Mars is the capital planet of the Federation .

To enter the Sol system a player must first obtain a permit from the Federation. This permit is given after gaining the rank of Petty Officer with the Federal Navy Auxilliary.

These are objects that have a near-Earth orbit, yet far enough from the Sun so that the surface material never evaporates, having a diameter over 50 metres. As of August 5, 2009, 6,244 near-Earth asteroids are known, ranging in size up to ~32 kilometers ( 1036 Ganymed ). [ 12 ] [ 13 ] The number of near-Earth asteroids over one kilometer in diameter is estimated to be 500 - 1,000. [ 14 ] [ 15 ] The composition of near-Earth asteroids is comparable to that of asteroids from the main asteroid belt, reflecting a variety of asteroid spectral types . [ 16 ]

A small number of NEOs are extinct comets that have lost their volatile surface materials. Although having a faint or intermittent comet-like tail does not necessarily result in a classification as a Near Earth Comet, making the boundaries somewhat fuzzy. The rest of the near-Earth asteroids are driven out of the asteroid belt by gravitational interactions with Jupiter . [ 3 ] [ 18 ]

Many Atens and all Apollos have orbits that cross (though not necessarily intersect) that of the Earth, so they are a threat to impact the Earth on their current orbits. Amors do not cross the Earth's orbit and are not immediate impact threats. However, their orbits may evolve into Earth-crossing orbits in the future.

All asteroids should be sorted using a 0-padded 8-digit sortkey created from the <year><day><month> of closest approach. For example, 1991 BA should use [[Category:Near-Earth objects in 1991|19910118]] for 1991 January 18.

A near-Earth object ( NEO ) is any small Solar System body whose orbit can bring it into proximity with Earth . By definition, a Solar System body is a NEO if its closest approach to the Sun ( perihelion ) is less than 1.3  astronomical unit (AU). [2] If a NEO's orbit crosses that of the Earth's and the object is larger than 140 meters across, it is considered a potentially hazardous object (PHO). [3] Most known PHOs and NEOs are asteroids . [1]

Known NEOs include more than seventeen thousand near-Earth asteroids (NEAs), more than one hundred near-Earth comets (NECs), [1] and a number of solar-orbiting spacecraft and meteoroids , large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of the Earth. [4] NEOs have become of increased interest since the 1980s because of increased awareness of the potential danger some of the asteroids or comets pose, and methods of mitigation are being researched. [5]

Based on the orbit calculations of NEOs, the risk of future impacts is assessed on two scales, the Torino scale and the more complex Palermo scale , both of which rate a risk of any significance with values above 0. Some NEOs have had positive initial Torino or Palermo scale ratings after their discovery, but as of January 2018 [update] , more precise calculations based on subsequent observations led to a reduction of the rating to or below 0 in all cases.
