System classifications

The Standardised Classification of Solar Systems Is a generalised form of classification of planet types around a star.

The Formula is [star type][how many planets from star][planetary type, terrestrial/gaseous][atmosphere, only applies to terrestrials] If moons are present, they are represented by the planet's type, plus [moon order from planet]

 Types: 

Different star types are O, B, A, F, G, K, M, and L, going in order of decreasing size and brightness.

There are 5 different types of planets. A is Terrestrial, B is Gaseous, C is Ice Giant, D is Dwarf Planet, and C is a liquid surface terrestrial.

There are 5 types of atmosphere, represented as -am1 through -am5. They only apply to terrestrial type planets, as any Gaseous Planet already has a Type 5 atmosphere.

Type 1 - Exosphere- Barely any atmosphere.

Type 2 - Light - Atmosphere is dense enough to produce notable wind and Weather effects.

Type 3 - Habitable- Atmosphere is abundant to allow a wide range of weather phenomena.

Type 4 - Dense- Atmosphere is above the range to crush humans, But survivable for probes and enclosed habitats.

Type 5 - Toxic - Atmosphere is completely unsurvivable at surface level due to density and/or toxicity. Probes may have short lifespans, or be instantly crushed.

 Examples: 

The 3rd planet from a G-type star, with a light atmosphere, would be G3A-am2

Alternatively, the 14th moon with little atmosphere, from the 5th planet from the sun, which is a gas giant, would be:

G5B14A-am1 (Star)-(planetnumber)-(planettype)-(moonnumber)-(moontype)
