The Worlds of the Solar System


The planets and moons orbiting our Sun 

The Inner Worlds

Vulcanus

The inner-most world of Sol, Vulcanus is a small, rocky world, scorched by the Sun and devoid of life. It was discovered in 1823 by Daniel Vulcanusworth, after whom it has been named.

Mercurius

Mercurius is the innermost of the ancient known planets. It is a small planet, with only simple siliceous proto-life on the surface forming strange patterns viewable from space. There are no great reserves of antibarides on Mercurius, or anything of the like, which means that there is most likely no interest in human development of the world, if it even were possible in such hostile environments. There is no atmosphere on Mercurius.

The silicate proto-life found on Mercurius is extremely well adapted to life in hot, atmosphereless environments. It is the origin to the strange, space-ship borne plague of "St. Peter's barnacles". The silicids bore into the metal and wood of mechanical things and produce an extraordinarily hard layer of dead material, resembling a layer of moss or lichen. Though they do not seem to survive low temperatures very well, you can still find remains clinging to the hulls of the few crafts returning from Mercury.

The Terrestrial Worlds

Venus

Venus is the third planet from Sun, and closely resembles its sister planet Tellus. Venus is a world of heavy atmosphere and high mountains: at the sea level, the pressure and heat of the air make it impossible for humans to live for any amounts of time, and thus humanity can be found in the high highlands. Venus is the home of the greatest mountains in the solar system, up to the 15 kilometers of Mt. Andiban. The seas of Venus are so hot that they may occassionally boil, and the humidity of the lowlands is very great. The surface of Venus is frequently covered in mist and clouds, especially below the habitable parts of the highlands, and thus Venus is frequently called the world of the Mist Sea.

There are areas above the mistline that have human habitation. Mountains and highlands break above the heat and pressure, and on the slopes and plateaus much terrestrial life exists, unlike on Earth. Humans live in scattered city states, which are connected by thermal and gas dirigibles and other atmonautical craft: the aerotechnical prowess of the Venereans is renown throughout the worlds.

The majority of arthroids live on Venus: arthroids are a species of large and intelligent arthropods who have, because of contact with humanity, evolved speech and extelligence.

Venus' day is about 1.9 Earth days, and its year is 118 venerean days long. Venus does not have any great seasonal changes because of it's near-zero axial tilt.

Venus has a ring of debris orbiting it, possibly the result of a destroyed moon. It is called the Veil.

Tellus

The Earth is the fourth planet from the Sun, a hospitable world of seas and land, with a gigantic satellite planet orbiting it. About 70% of the surface is water, and the rest is land that can rise up to 8 kilometers above ground in mountainous regions. There are seven great landmasses: the two Americas, Australia, Asia, Africa, Antarctica and Greenland.

The Earth is most probably the origin of the biological area that comprises the Terrestrial worlds, and it most certainly is the origin of the primate species human. The human is a hairless bipedal mammal, who uses her hands in most ingenious ways. The human was the first species of the Terrestrial biosphere to evolve language, and uses it to form extelligent groups called "cultures". This super-biological construction enables the human to perform extraordinary feats with the physical world, and the inner construction of its mnemetical systems. The human has spread from Earth to Venus, but has not found foothold on Mars or Selene, except as an extension of its extelligence.

There is a small arthroid presence on a southern island, where also descendant reptilians of the ancient sauruses live.

Selene

The Moon, Luna or Selene is the gigantic satellite of Tellus, formed when an unknown planet and Earth collided in the astronomical past. Earth ejected great amounts of matter, much of which were the remnants of antibaric trace amounts of matter left on it, resulting in a moon with a greater than usual antibaric composition.

The Moon has only a very thin atmosphere, constantly leaked from and generated by its subselenous biosphere that is confined to the huge system of caverns flooded with oceans of sealants and water-seas beneath the surface. Life on Selene is gaian, and is probably the oldest area of terrestrial life after Earth itself.

Selene has very slight seismic activity, caused by the friction between antibaric and probaric matter.

Mars

Mars is the smallest of the three Terrestrial planets orbiting the Sun directly, but not nearly as small as Selene. It is a world of cold and sandy plains and desert, with extremely cold polar regions, almost devoid of ice.

Plant-life on Mars performs its photosynthesis with red leaves instead of green, which absorb more of the copious green light sent out by the sun.

Mars has no human presence, but it does have primates - the gigantic Martian apes.

Mars has three small satellites: Metus, Timor and Bellona.

The Solar Rings

Nemesis' Tail

Nemesis' Tail is the ring of debris orbiting the Sun that was formed when the antibaric-betaneutral rocky planet Nemesis entered the Solar System and was ripped apart by the gravity of the Sun and the planets. The ring orbits the Sun in a highly elliptical path, and its overlaps the paths of the Terrestrial planets, causing great meteor storms.

The Tail is the main source of antibarics on the Terrestrial worlds, and the only viable source of betaneutral matter in the whole Solar System.

Asteroid Field

The Asteroid Field is a very sparsely populated ring of debris around the Sun, orbiting between Mars and Jupiter. It is not very interesting.

The Jovian Worlds

Jupiter is the sixth planet from the Sun. It is the largest planet in the Solar system, and the first of the gas giants, the large planets made mainly out of gases and without rocky surfaces.

Jupiter radiates thermal energy into the space surrounding it, causing the Jovian biosphere to be almost as warm as that of the Gaian biosphere.

Four satellite planets orbit Jupiter, with an assortment of other minor planets and planetoids.

Io

Io is the first satellite planet of Jupiter, and the smallest. Not much if known of it.

 

Europa

Europa is the second world of Jupiter. Not much is known of it.


Ganymedes

Ganymedes is the largest of the Jovian worlds, slightly larger than Earth. It is most probably the origin of the Jovian biosphere. Not much is known of it.


Callisto

Callisto is the fourth world of Jupiter. Not much is known of it.


Saturnus

Saturnus is the seventh planet of the Solar System, and a gas giant. It has a splendid ring of debris and several large planets orbiting it - but there seems to be no life. Saturnus, unlike Jupiter, is cold, and the Saturnalians are likewise.

Significant satellites: Hyperion, Theia, Tethys, Rhea, Mnemosyne and Iapetus.


Minerva

Minerva is the eighth planet from the Sun. It has several planets orbiting it, amongst them Pallas, Arachne, Nike and Medusa.


Nox

Nox is the ninth and last planet of Sol, and the last gas giant. It has a satellite, the gigantic rocky planet Thanatos, which is about three times the size of the Earth.
