The Traveller5 Second Survey format defines a standard for describing star systems in the Official Traveller Universe. It is composed of a series of fields describing various aspects of the Main World (MW) in each system including physical and cultural characteristics, and some details about other bodies in the system of interest to travellers.
The data for Regina (Spinward Marches 1910), home of Duke Norris and an influential world on the edge of the Third Imperium can be summarized in Second Survey format as:

The location of the world within a sector, given as a
four digit number identifying a position on a hexagonal grid.
The first two digits are the distance from
the spinward edge in parsecs ranging from 01
through 32. The second two digits are the distance
from the coreward edge in parsecs ranging from 01

The second eHex digit is the number of
planetoid belts in the system. A Main World of
size 0 is termed an asteriod belt, and is not
counted here.
If unknown, ? can be specified.

This is given as a decimal integer, and will always be at least 1 (the Main World) plus the number of planetoid belts (see PBG) plus the number of gas giants (see PBG) but will include other planets orbiting the star(s) in the system.
Note that gas giant satellites are not counted, unless
the satellite is the Main World itself - identified with
remark Sa.

Traveller5
The allegiance code is a 4-character code which is selected to uniquely identify a polity in Charted Space. Previous editions used a 2-character code (see below).
| Code | Pre-T5 | Description | Location |
|---|
Classic Traveller, MegaTraveller, Traveller: The New Era, Traveller: 4th Edition
Older versions of Traveller use a 2-character code. Due to the limited number of useful 2-character codes, these are not unique across Charted Space. In addition to the secondary entries in the above table, the following codes are seen:
| Code | Description | Edition |
|---|---|---|
Dr

Dd
| Domain of Deneb | MegaTraveller. |
Fd

Stellar Data
1910 Regina A788899-C Ri Pa Ph An Cp (Amindii)2 { 4 } (D7E+4) [9C6D] BcCeF NS - 703 8 ImDd F7 V BD M3 VStellar data lists the stars in the system.
Normal stars fuse hydrogen, and occur in a variety of colors (due to temperature) and sizes (sub-dwarfs to super-giants). After a dwarf star exhausts its fuel it will briefly become a cool red giant then leave behind its core as an incredibly dense and bright white dwarf. A giant star will explode and leave behind an even denser neutron star or black hole. An object too small to fuse hydrogen but large enough to fuse deuterium is known as a brown dwarf.
Normal stars are described by their
spectral class and luminosity. This uses a subset of the
Morgan–Keenan classification system
(also known as Yerkes or MKK), such as G2 V where G2
is the color/temperature (2⁄10th of the way
from yellow G to orange K on the spectrum) and
V is the luminosity/size (main sequence).
Stellar Spectral Class
| Code | Description | Temperature (K) |
|---|---|---|
O
| Blue | >33,000 |
B
| Blue-White | 10,000-33,000 |
A
| Blue-White | 7,500-10,000 |
F
| Yellow-White | 6,000-7,500 |
G
| Yellow | 5,200-6,000 |
K
| Orange | 3,700-5,200 |
M
| Red | 2,000-3,700 |
Stellar type indicates the spectral classification of a star; colors are the essential perceived colors of the star's visible light.
Stellar Luminosity
The luminosity gives the magnitude, or brightness of the star. This correlates with the size of the star, although it varies depending on spectral class.
| Code | Description | Diameter (Sol = 1) |
|---|---|---|
Ia
| Bright Supergiant. | 52 - 3500 |
Ib
| Weak Supergiant. | 30 - 3000 |
II
| Bright Giant. | 14 - 1000 |
III
| Normal Giant. | 4.6 - 360 |
IV
| Subgiant. | 3.3 - 13 |
V
| Main Sequence Star. | 0.2 - 10 |
VI
| Subdwarf. | 0.1 - 1.2 |
D
| White Dwarf. | 0.006 - 0.018 |
Classic Traveller, MegaTraveller, Traveller: The New Era, Traveller: 4th Edition
White dwarfs (the cores of dead stars) are represented by the size
code D, optionally followed by a spectral code,
e.g.
DB,
DA,
DF,
DG,
DK,
DM.
(Note: This differs significantly from the real-world
classification of white dwarfs.)
Some files may use luminosity code VII for white
dwarfs instead.
The special code BH may be used for black holes.
Traveller5
White dwarfs are represented by the size
code D with no spectral code.
The special code BD may be used for brown dwarf,
sub-stellar objects.
The special code BH may be used for black holes.
The special code NS may be used for neutron stars.
The special code PSR may be used for pulsars, rapidly spinning neutron stars with active radio beams.
eHex - Extended Hexadecimal
Traveller encodes numbers using "extended
hexadecimal", which is really a way of encoding numbers larger
than 9 into a single printable character. Numbers in the range
0-9 are represented as 0-9 as normal.
Like hexadecimal, values in the range 10-15 are represented
as A-F (always uppercase). But the
encoding continues for values in the range 16-17
as G-H, 18-22
as J-N, and 23-30
as P-W.
Codes X, Y and Z may be
used for 31-33 or may be reserved for exceptional values.
Code X, in particular, is reserved
for unknown values, such as the details of intentionally
unexplored systems. Codes I and O are
unused to avoid confusion with
1 and 0.
In fields such as UWP and PBG
you can use ? to represent unknown values.
