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 |
|
Type: Barren Rocky Planetoid Average Temp: 200C to -200C Average Mass: Around 0.1 Earth
Masses |
|
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 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 |
|
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 |
|
Type: Asteroidal Body Average Temp: -100C to 100C |
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 |
If you know a
system containing this type of star |
BLUE | |
Type: Type A hot blue star Average Surface Temp: 9000C Average Mass: 1,700,000 Earths Comment: Quite uncommon Type A's are the smaller brother of Type B's although they still produce a respectable amount of light and heat. |
If you know a
system containing this type of star |
Type: Type B hot blue star Average Surface Temp: 20000C Average Mass: 7,000,000 Earths Comment: Impressive stars that are capable of sustaining life on planets far away from them. Good example of this is Achenar |
|
Type: Blue Supergiant Star Average Surface Temp: 13000C Average Mass: 71,000,000 Earths Comment: These awesome stars are extremely rare and extremely short lived, the only know example nearby is in the Rigel (92,6) system. |
