Class A:
Planets of this class are usually found in a star's outer or "cold zone".
They are typically 140 thousand to 10 million kilometers in diameter and have
high core temperatures causing them to radiate heat. Low stellar radiation and
high planet gravity enables them to keep a tenuous surface comprised of gaseous
hydrogen and hydrogen compounds.
Some Examples Include:
Alpha 4 & 5, Antares 4 & 5, Antos 5, Arcturus 5, Argelius 5, Betelgeuse
3, Canopus 6, Eminiar 10, Herculis, Jupiter (Sol 5), Rigel 13, Spica 1 &
2, UFC 892 10 & 11, Vega 5 & 6.
Class
B:
Class B Planets are usually found in a star's outer or "cold zone".
They are typically 50 thousand to 140 thousand kilometers in diameter and have
high core temperatures but do not radiate much heat. Low stellar radiation and
high planet gravity enables them to keep a tenuous surface comprised of gaseous
hydrogen and hydrogen compounds.
Some Examples Include:
61 Cygni 7, Alpha Centauri 6, Arcturus 6 & 7, Argelius 6 & 7, Betelgeuse
4 & 5, Canopus 7, Epsilon Bootis 4, Epsilon Indi 7 & 9, Neptune (Sol
8), Procyon 5, Rigel 10, 11 & 14, Saturn (Sol 6), Uranus (Sol 7)
Class
C:
Planets of this
class are usually found in a star's "habitable zone". They are typically
10 to 15 thousand kilometers in diameter. They have high surface temperatures
due to the "greenhouse effect" caused by their dense atmospheres.
The only water found is in vapor form.
Some Examples Include:
61 Cygni 2 & 3, Alpha Tauri 2, Arcturus 2, Argelius 1, Epsilon Indi 2, Medusa,
Rigel 1, Sirius 2, Tau Ceti 2, Tholia, Venus (sol 2).
Class
D:
Planets of this
class are usually found in a star's "habitable zone". They are typically
10,000 to 15,000 kilometers in diameter. They have a molten surface because
they have been recently formed. The atmosphere contains many hydrogen compounds
and reactive gases. Class D planets eventually cool, becoming Class E.
Some Examples Include:
Epsilon Indi 3, Excalbia
Class
E:
Planets of this class have
a molten core and are usually found in a star's "habitable zone".
They are typically 10,000 to 15,000 kilometers in diameter. Their atmospheres
still contain hydrogen compounds. They will cool further eventually becoming
Class F.
Some Examples Include:
61 Cygni 4, Altair 3, Arcturus 3, Capella 3, Canopus 4, Janus 6, Rigel 3, Vega
3
Class F:
Class F planets are usually found in a star's "habitable zone". They
are typically 10 to 15 thousand kilometers in diameter and have surfaces that
are still crystalizing. Their atmospheres still contain some toxic gases. They
will cool eventually becoming Class C, M or N.
Some Examples Include:
Delta Vega 2, Vega 4
Class G:
Planets of this class can be found in any of a star's zones. They are typically
8 to 15 thousand kilometers in diameter. Their surfaces are usually hot. Their
atmospheres contain heavy gases and metal vapors.
Some Examples Include:
Capella 4, Ceti Alpha 5, Rigel 12, Tau Ceti 5, Taurus 2, Triacus (Epsilon Indi
4)
Class H:
Planets of this class are usually found in a star's "habitable zone"
or "cold zone". They are typically 1,000 to 10,000 kilometers in diameter.
They have partially molten surfaces and atmospheres that contain many hydrogen
compounds. They cool becoming Class L.
Some Examples Include:
Alpha Centauri 5, Gothos, T'khut (40 Eridani 2)
Class I:
Planetary bodies of this class can be found in any of a star's zones. They are
usually found in orbit of larger planets or in asteriod fields. They are typically
100 to 1,000 kilometers in diameter. They have no atmospheres. Their surfaces
are barren and cratered.
Some Examples Include:
Ceres, Deimos, Kera, Luna, Phinda, Phobos
Class J:
Planets of this class are found in a star's "hot zone". They are typically
1,000 to 10,000 kilometers in diameter. They have high surface temperatures
due to the proximty to the star. Their atmospheres are extremely tenuous with
few chemically active gases.
Some Examples Include:
Alpha Centauri 1, Alpha Tauri 1, Altair 1 & 2, Arcturus 1, Canopus 1, Capella
1 & 2, Deneb 1, Mercury (Sol 1), Procyon 1 & 2, Sirius 1, Vega 1 &
2
Class K:
Planets of this class are usually found in a star's "habitable zone".
They are adaptable for humanoid colonization through the use of pressure domes
and other life support devices. They are typically 5,000 to 10,000 kilometers
in diameter. They have thin atmospheres. Small amounts of water are present.
Some Examples Include:
Alpha Centauri 2 & 3, Alpha Taur 4, Altair 6, Antares 2 & 3, Argelius
3 & 4, Betelgeuse 2, Canopus 5, Mars (Sol 4), Mudd, Procyon 4, Rigel 9,

Class L:
Planets of this class are usually found in a star's "habitable zone"
or "cold zone". They are typically 1,000 to 10,000 kilometers in diameter.
Low solar radiation and minimal internal heat usually result in a frozen atmosphere.

9), Psi-2000, Sauria, Sirius 8 & 9, Time Planet
Class M:
Planets of this class are found in a star's "habitable zone". They
are typically 10,000 to 15 thousand kilometers in diameter. They have atmospheres
that contain oxygen and nitrogen . Water and life-forms are typically abundant.
If water covers more than 97% of the surface, then they are considered Class
N.

Class N:
Class N planets are usually found in a star's "habitable zone". They
are typically 10,000 to 15 thousand kilometers in diameter. They have atmospheres
that contain oxygen and nitrogen . Water and life-forms are typically abundant.
If water covers less than 97% of the surface, then they are considered Class
M.
Some Examples Include:
Argo, Ascella, Canopus 8, Deneb 3
Class S:
Planets of this class are usually found in a star's "cold zone". They
are typically 50 million to 120 million kilometers in diameter and have high
core temperatures causing them to radiate heat and light. These are the largest
possible planets, because most planetary bodies that reach this size do become
stars.
Some Examples Include:
Bader Beta 10, Bruedon Beta 4, Horst 10, M'kyru Epsilon 4, Morphus, Delta 10,
Pandemus Epsilon 5, Ruhr Beta 6, Rydle Delta 7, Shonoisho, Delta 6
Class T:
Planets of this class are usually found in a star's "cold zone". They
are typically 10 to 50 million kilometers in diameter. They have high core temperatures
causing them to radiate enough heat to keep water in a liquid state.
Some Examples Include:
Bruedon Epsilon 5, Optima Alpha 5
Class Y:
Class Y - Demon Planets and planetoids of this class can be found in any of
a star's zones. They are typically 10,000 to 15 thousand kilometers in diameter.
Atmospheric conditions are often turbulent and saturated with poisonous chemicals
and thermionic radiation. Surface temperatures can reach in excess of 225 C.
Starfleet Note:
Communication is frequently impossible, and transport may be difficult. Simply
entering orbit is a dangerous prospect. No known environment is less hospitable
to humanoid life than a Class Y planetary body.
