VELA SYSTEM: OVERVIEW |
|
The Vela system is
somewhat of a geographical oddity, quite what happened in the systems
earliest days is unknown, but it is thought that systems largest gas
giant, Maloth migrated inwards disrupting other rocky worlds, leading to
the capture of two, if any other worlds existed (which according to the
geology of what was left behind is very likely) they have been flung out
into interstellar space. The current system consists of a standard G
type star, two large gas giants, and extensive belt systems throughout
the inner region of the system. The system was federation founded in
earth year 2121. Astro-archaeology has brought up potential evidence of
manipulation of the system, this would explain the surprisingly earth
like satellites of Maloth, whose environments are so very similar.
However no artifacts have been recovered. Table below lists main
stars, then planets and belts in increasing orbital radius. Name: Vela Class: G0 V Luminosity: 1.25x sol Radius: 1.05x sol Surface temperature:
6030K Rotational period: 12
days Age: ~3,500,000,000
years Summary: bright G type
star, strange fast rotation, but in other respects typical, weather is
occasionally violent, with mass ejection storms cycling every 20 years
or so, the effect on planetary systems is however minimal. Belt: Extent: orbits between
45m km, and 70m km Density: moderate, most
bodies lie in a band between 61m km, and 63m km Object size
distribution:
~4400 objects 50km+
~1000 objects 150km+
5 objects 300km+
0 objects above 600km Composition: nearly all
metallic, some stony and igneous, thought to be planetary remnants, or a
region of planetesimals that never formed to create a planet. Summary: This belt is
typical of the inner belts found in the Vela system, many asteroids in
this belt have been dismantled for ship manufacture for the various
shipyard in this system, this belt is particularly favored because of
the high density of the asteroids, and structural integrity. Name: Vela region 2 Extent: orbits between
86m km, and 109m km Density: poor, most
bodies lie in a band between 61m km, and 63m km Object size
distribution:
~1600 objects 50km+
~300 objects 150km+
3 objects 300km+
0 objects above 600km Composition: large
mixture of types, thought that this region condensed from material
perturbed by Maloth, metallic is dominant but large amounts of all types
can be found, silicaceous and carbonaceous most significant of these
others. Summary: typical for
the vela system, again probably debris from early formation, some
objects used for ship manufacture, carbonaceous chondrites been used to
create the orbital tethers in system, a few have been hollowed and
inhabited, mostly these have become research facilities. Name: Maloth Mean orbital radius:
165m km Rotational period 16hrs Planetary diameter:
161000 km Year length: 413 days Average temp:

core assumed to be silicaceous Density: 1.21 Surface g: 27.22m/s/s Axial inclination: 1° Magnetic field: massive
and stable Moons:
Extensive 12 major satellites, with very different types present. Two
possess life, one seemed to have transferred life to the other about
2.3billion years ago, as biochemistry seems to share a common ancestor,
probably bacterial conveyed by meteorite impact. The two major moons are
listed below. Major
ring systems at orbits:
512000km-551000km
721000km- 801000km

1% other, mostly carbon dioxide and argon Density:
5.61 g/cm^3 Surface
g: 9.96m/s/s Orbital
inclination: 5° Magnetic
field: moderate, fairly stable similar to Earth’s Summary:
life bearing satellite, more information here. Summary: super-jovian
planet, unusual and nearly unprecedented in satellite type within
federation space, planet thought to have migrated inwards. The larger
moons are thought to have been captured during this migration, life
seems to have emerged when these planets had settled into their orbits,
and not from pre-capture times. Name: Vela region 3 Extent: orbits between
342m km, and 412m km Density: poor, bodies
scattered loosely within this band, no major regions Object size
distribution:
~400 objects 50km+
5 objects 150km+
1 object 300km+
0 objects above 600km Composition: great
range can be found in this belt, with metallic being dominant, also some
icy bodies can be found, and also large regions rich in scattered debris
(particle size average less than 5mm). Summary: This is the
last major belt in the Vela system and also the least material
containing, its origins are not clear, as Maloth should have swept this
region clear in its migration some suggest that Maloth displaced these
bodies as it moved inwards flinging them out behind it. Name: Forax Mean orbital radius:
3900m km Rotational period 17hrs Planetary diameter:
62000km Year length: ~47000
days (~130years) Average temp: ~60K Atmosphere:
gas giant type, Atmosphere
quite calm, though storms seem to coincide with the seasons. Density: 1.37 g/cm^3 Surface g: 11.8 m/s/s Axial inclination: 60° Magnetic field:
pronounced Moons:
mostly debris, 15 moons (icy) above 50km diameter
No significant ring systems Extra notes on system
The
rotation of the two large satellites Alva and Anan should be tidally
locked to their planet, but this is not so, though the length of day is
beginning to lengthen. The
Vela system has only recently been included within in the federation,
and forms one of the outpost systems. There is small scale ship
manufacturing between vela regions 1 and 2, and the population in the
asteroid complexes that attend them is less than 5000. If
intelligent life does emerge, and forms a civilization on either of
Maloth’s inhabited moons then the federation with have to withdraw
from those worlds, and remove all traces that it was. This can be done
quite quickly on Anan, with orbital tether in place people can be
shipped to the asteroid settlements in the inner belts, or be taken by
wormhole gate to the federation main. Though it is far more likely that
any disembarkment can occur at a much more leisurely pace, with the
thorough removal of all traces of habitation, and then as the infant
civilization starts to mature, the removal of the various orbital
facilities, and finally culminating in crashing the modified asteroids
into the sun. |
