This page details the '''Stellar Classification''' system used in [[Starship Simulator]] to categorize stars based on their spectral characteristics, temperature, and luminosity. The game utilizes the real-world '''Morgan-Keenan (MK) System'''.

== Overview ==
Stars are classified by a string of characters (e.g., '''G2V'''). This code provides a snapshot of the star's surface temperature, its position within a temperature bracket, and its size/brightness (luminosity).

* '''Letter (O-Y):''' The Spectral Class (Temperature).
* '''Number (0-9):''' The Numerical Sub-class (Temperature precision).
* '''Roman Numeral (I-VII):''' The Luminosity Class (Size/Life stage).

== Spectral Classes (OBAFGKMLTY) ==
The primary sequence runs from the hottest (O) to the coldest (Y). A common mnemonic to remember the main sequence is: ''"'''O'''h, '''B'''e '''A''' '''F'''ine '''G'''irl/'''G'''uy, '''K'''iss '''M'''e, '''L'''ovenly '''T'''oday, '''Y'''ay."''

{| class="wikitable" style="width: 100%;"
! Class !! Color !! Temperature (Kelvin) !! Characteristics
|-
| style="background:#9bb2ff;" | '''O''' || Deep Blue || > 30,000 K || Extremely hot and massive; very rare and short-lived.
|-
| style="background:#bbccff;" | '''B''' || Blue-White || 10,000 – 30,000 K || Highly luminous; often found in young stellar clusters.
|-
| style="background:#f8f7ff;" | '''A''' || White || 7,500 – 10,000 K || Common naked-eye stars with strong hydrogen lines (e.g., Sirius).
|-
| style="background:#fff4ea;" | '''F''' || Yellow-White || 6,000 – 7,500 K || Slightly hotter and larger than the Sun.
|-
| style="background:#fff200;" | '''G''' || Yellow || 5,200 – 6,000 K || "Yellow Dwarfs" like our Sun (Sol is a G2V).
|-
| style="background:#ffad5b;" | '''K''' || Orange || 3,700 – 5,200 K || "Orange Dwarfs"; Slightly cooler and smaller than the Sun.
|-
| style="background:#ff6060;" | '''M''' || Red || 2,400 – 3,700 K || "Red Dwarfs"; the most common type of star in the galaxy.
|-
! colspan="4" | Extended Classes (Brown Dwarfs)
|-
| style="background:#b03060;" | '''L''' || Deep Red || 1,300 – 2,400 K || Very cool objects; transition between stars and brown dwarfs.
|-
| style="background:#800080; color:white;" | '''T''' || Magenta/Methane || 700 – 1,300 K || Methane-rich brown dwarfs; emit mostly infrared light.
|-
| style="background:#4b0082; color:white;" | '''Y''' || Ultra-Cool || < 700 K || Theoretical "Cold" brown dwarfs; surface temps can be room temperature.
|}

== Numerical Sub-classes (0–9) ==
Each letter class is divided into ten sub-divisions to provide more detail on temperature.
* '''0''' is the '''hottest''' end of a class.
* '''9''' is the '''coolest''' end of a class.

''Example: An '''A0''' star is significantly hotter than an '''A9''' star. Following the sequence, an '''A9''' is only slightly hotter than an '''F0'''.''

== Luminosity Classes (Roman Numerals) ==
The Roman numeral at the end of the spectral type describes the star's size and "Luminosity." This tells you if the star is a tiny dwarf or a massive supergiant.

* '''0 / Ia-0:''' Hypergiants (Extremely rare and massive)
* '''I:''' Supergiants (Ia: Luminous, Ib: Less Luminous)
* '''II:''' Bright Giants
* '''III:''' Giants
* '''IV:''' Subgiants
* '''V:''' Main Sequence (Dwarfs) — ''This is where the Sun and most stable stars live.''
* '''VI:''' Sub-dwarfs
* '''D / VII:''' White Dwarfs (Remnants of dead stars)

== Example Breakdown: '''Sol''' (''Our Sun'') G2V ==
* '''G:''' Spectral Class (Yellow, ~5,800 K).
* '''2:''' Sub-class (Hotter end of the G-scale).
* '''V:''' Luminosity Class (Main Sequence Dwarf).
