Spacefarers Guide to Planets

 
Spaceflight requires knowledge of the the bodies around you, this is a comprehensive guide to the different types of stars and planets one may find while on thier travels.
 
   

Information Picture
Type:   Sustained Terraformed World

Average Mass: 0.1 - 0.5 Earth Masses

Comment: These are small rocky planets that just happened to be within the right temperature range for life, Terraforming a planet is a much more economical in the long run then building stations for a growing population. Only found in well developed systems that need the extra space. Due to its low gravity "Sustained" world needs constant attention to keep its life supporting properties. The most famous Terrerformed world is Mars from the Sol system which provides much needed space for Earths population.

Type:   Terraformed world with introduced life

Average Temperature: 20C

Average Mass: 0.5-2.0 Earth Masses

Comment: Larger type of the two types of Terraformed worlds, these are usually terraformed for the purpose of space or to grow foodstuffs. They are large enough to sustain terraforming without help.

Type: World with oxygen atmosphere and Indiginous life

Average Temp: 20C

Average Mass: 0.7-2.0 Earth Masses

Comment: These worlds are surprisingly common in the galaxy, the closest to Sol being in the system Tau Ceti, Worlds with indiginous life can be both troublesome and very rewarding to the newly arrived settler, the life forms on these planets may be dangerous or they may be profitable and unique.

Type: Small Gas Giant

Average Temp: From 50C to -250C

Average Mass: Around 15 Earth Masses

Comment: Commonly found planet throughout the galaxy, the small gas giant is useful in the scooping of hydrogen and other gasses.

Type: Medium Gas Giant

Average Temp: From 50C to -200C

Averge Mass: Around 100 Earth Masses

Comment: Commonly found planet throughout the galaxy, the medium gas giant is useful in the scooping of hydrogen and other gasses. Although it should be noted that the medium gas giant can be dangerous to the larger ships scooping gas, as the gravitational pull can suck an unwary pilot in.

Type: Large Gas Giant

Average Temp: From 50C to -200C

Average Mass: Around 300 Earth Masses

Comment: Commonly found planet throughout the galaxy, the large gas giant is useful in the scooping of hydrogen and other gasses. Although it should be noted that the large gas giant can be very dangerous to the larger ships scooping gas, as the gravitational pull can suck an unwary pilot in.

Type: Very Large Gas Giant

Average Temp: From 50C to -200C

Average Mass: Around 2000 Earth Masses

Comment: One of the rarer planets a very large gas giant is almost a star. Due to thier high gravity they can be very dangerous for larger ships. They are commonly mined for thier hydrogen to provide fule for ships.

Type: Rocky Planey with thin atmosphere

Average Temp: 100C to -100C

Average Mass: Around 0.5 Earth Masses

Comment: These bleak worlds provide the resources required for modern life, they commonly feature mining stations. Almost all mining is now done on either planets of this type or barren airless planetoids. These planets are sometimes also capable of being terraformed which can be an asset to expanding systems.

Mars was a good example of this type of planet but it has been terraformed.

Type: Barren Rocky Planetoid

Average Temp: 200C to -200C

Average Mass: Around 0.1 Earth Masses

Comment: Common mining planet, usually bleak and cold, These planets only offer a wealth of minerals to persuade settlers. Found almost everywhere in the universe

Type: Rocky World with thick corrosive atmosphere

Average Temp: Up to 500C

Average Mass: Around 1 Earth Mass

Comment: These worlds are useless and deadly, one cannot even begin to set up mining operations before the acidic atmosphere has reduced your MB4 to a boiling pool of metal. Avoid at all costs

Notable planets of this type include Venus and Achenar 5

 

Type: Highly Volcanic worlds

Average Temp: Around 150C

Average Mass: Between 0.05 and 2 Earth Masses

Comment: These planets are highly dangerous but also provide a large amount of cheap energy to those willing to tap it with the use of coils around the planet.

Notable planets of this type are Lucifer in the Sirus system and IO in the Sol system

Type: World with water weather system and corrosive atmosphere

Average Temp: Around 10C

Average Mass: Around 1 Earth Mass

Comment: These planets are those which would have sustained life but for some reason cannot, usually because of radiation from a nearby star. They initially appear tempting but soon turn out to be inhospitable and costly.

Notable planets or this type are Eden in the Alpha Centauri system

Type: World with ammonia weather system and corrosive atmosphere

Average Temp: -100C to 50C

Average Mass: Around 1 Earth Mass

Comment: Previously thought devoid of life these planets are in fact possible homes to the Thargoids, who have evolved many adaptions to cope with the harsh conditions. Of little economical value to humans these systems demonstrate that Thargoids and humans could co-exist.

Notable systems include Pleione 4b a base of the Thargoids

Type: World with methane weather system and corrosive atmosphere

Average Temp: -100C to 50C

Average Mass: Around 1 Earth Mass

Comment: Dangerous and of little economic value, avoid at all costs.

Type: Small Barren sphere of rock

Average Temp: -100C to 100C

Average Mass: 0.01 Earth Mass

Comment: Too small to mine profitably, these planets have little use.

Type: Asteroidal Body

Average Temp: -100C to 100C

Average Mass: 0.001 Earth Mass

Comment: Bordering on asteroids these are too small to mine profitably.


Spacefarers Guide to Stars

Stars can be devided up into four categorys based on thier colour. Thes categorys are Brown, Red, Orange, Yellow, White and Blue

BROWN
Type: Brown Dwarf Substella object

Average Surface Temp: 1000C

Average Mass: 25000 Earths

Comment: Cross between a very large gas giant and a very small star

 

RED
Type: Faint Type M Red Star

Average Surface Temp: Around 3500C

Average Mass: 70000 Earths

Comment: Small and dim this star precludes the chance of life forming in the system in which it exists. Its less stable counterpart is known as the type M Flare star. One of the most common stars in the universe.

Type: Type M Red Star

Average Surface Temp: Around 3000C

Average Mass: 80000 Earths

Comment: Brighter than the Faint Type M, this red star is very common. Unlikely candidate for life but it may be possible on inner planets.

Type: Type M Flare Star

Average Surface Temp: Around 3000C

Average Mass: 30000 Earths

Comment: Common star, smaller and more unstable than other red star types. Life extremely unlikely due to hard radiation from solar flares.

Type: Red Giant Star

Average Surface Temp: Around 4000C

Average Mass: 300,000 Earths

Comment: While capable of sustaining life these stars are rather unstable and short lived.

ORANGE
Type: Type K Orange Star

Average Surface Temp: Around 5000C

Average Mass: 160,000 Earths

Comment: Relatively bright and stable the Type K orange Star makes a good star for life. Unstable counterpart Type K Flare Star

 

Type: Bright Giant Star

Average Surface Temp: Around 8000C

Average Mass: 7,000,000 Earths

Comment: Uncommon Giant star. Quite capable of supporting life. Bright Giant Star systems of note are: Canopus (6,-6), Alioth (0,4), Dubhe (-3,7), Alcyone (32,32), Polaris (0,76)

Type: Supergiant Star

Average Surface Temp: Around 3500C

Average Mass: 7,000,000 Earths

Comment: Very uncommon giant star. Rather impressive but rare. Supergiants of note are: Antares (-39,-34) and Betelgeuse (59,14)

YELLOW
Type: Type G yellow star

Average Surface Temp: 6000C

Average Mass: 340,000 Earths

Comment: Our sun is a type G yellow star so human settlers are often the most comfortable when being settled under systems of the same type. While average in most respects Type G's are perfect for life.

WHITE
Type: White Dwarf Star

Average Surface Temp: 10000C

Average Mass: 250,000 Earths

Comment: Although quite hot these stars are too small to produce enough heat or light, I had a lot of trouble getting close enough to take a picture as their gravity sucks you in when you get too close. Notice the rings of gas around it, these are remnants of the star it used to be.

Type:Type A hot white star

Average Surface Temp: 9000C

Average Mass: 700,000 Earths

Comment: Slightly hotter and brighter then its Type F brother the type A makes a fine star for life.

Type: Type F hot white star

Average Surface Temp: 7000C

Average Mass: 700,000 Earths

Comment: Although not as bright as a Type A it is still a good star for life

Type: Bright White Giant Star

Average Surface Temp: 8000C

Average Mass: 7,000,000 Earths

Comment: Fairly rare star, it is unsuitable for life due to its unstable nature
