Planet Classifications

Class

A Gas Giants, 500,000 to 15,000,000 km in diameter

B Ice Giants, 30,000 to 100,000 km in diameter

C Venus-like Planets with a greenhouse effect and noxious gasses and acids

D Lava Planets

E Mineral-Rich Worlds like Janus VI

F Young Earthlike World, still evolving

G Desert Planet, hot, only occasionally capable of supporting life

H Small Rock World with diverse, gaseus atmosphere

I Small, Rock World, and sometimes like Pluto, is made up of mostly Ice

J Toxic, uninhabitable World, like Gothos

K Cold, Desert World with a Thin Atmosphere, like Mars

L Oxygen-Argon World, somewhat Earthlike, life seldom develops, and sometimes climate, in part of in full, is

hotter and colder almost beyond habitability

M Earthlike Planets that have life, sometimes Sentient Life

N Ocean World, like Argo

O Ice World

P Water-Ice Worlds

Q Worlds with erratic orbits and wildly erratic climate

R Rogue Planet, occasionally with a strong Greenhouse Effect that's self-sustaining

S Brown Dwarf, 15,000,000 to 5,000,000,000 km

T Gas Supergiant with liquid oceans, 10,000,000 to 20,000,000 km i diameter

U Methane Planet, sometimes supports alien life

V Dimensionally Phased Planet

W Diamond Planet

X Extremely Unstable Planet

Y Extremely Poisonous Lava World with some significant land masses, chemical mixtures that are too toxic for

even life like the Tholians, Ariolans, and Sholians to evolve

Z Multidimensional World with Weird Chemical/Mineral Compositions

Any planet not a Gas Giant is typically .5g to 1.5g (6,500 to 19,500 km in diameter), and sometimes Rock Worlds are Uberearths 1.6g to 8g (19,800 to 104,000 km), and some classes such as the Class H, I, O, P, Q, and some X, Y and Z Planets are .1g to .4g (1,300 to 5,200 km)
