If checked, the world details (as edited by the user) will be downloaded along with the system details when the user presses on one of the large red buttons.Click on any details button next to a planet to generate more details at random. The details will appear in a new edit box overlaying the web page.

Orbit number (decimal) around parent star. This can be adjusted with the arrow buttons.Orbital Distance:
The world's rotational period is the same as its orbital period and cannot be changed. The Axial Tilt is zero and cannot be changed. One side is always facing towards the star and is permanently day, the other is permanently night. The 'day' and 'night' sides are set to the upper and lower temperature limits which is based on the atmosphere.
The world's rotational period is the same as its orbital period and cannot be changed. The Axial Tilt represents the inclination of its orbit around the planet relative to the planet's orbit around the star and so there can be seasonal influences. One side is always facing towards the planet, leading to long days and nights relative to the parent star. Note: The T5 rules specify that satellite orbits 'em' and closer will be locked to their planet. If a randomly generated satellite rotation or user entered result is greater than the orbital period, it will be reduced to the orbital period and regarded as tidally locked.
Diameter (km):
Equatorial Diameter of world in kmJump Point (km):
Distance required to safely jump. This distance includes clearing a planet's jump point for satellites, and the star.Time to Jump Point at ...:
Time to jump point at standard Gs from Maneuver Drives.Density Type:
Basic internal materials of world.Density (Earth=1):
Density where Earth = 1Mass (Earth=1):
Mass in Earth Masses - calculatedGravity (G):
Calculated gravity in Gs (Earth=1)Orbital Period:
Calculated Orbital period in Earth YearsRotational Period (Hours):
Rotational Period in Earth Hours. If Tz or Lk, rotation period & orbital period are the same.Atmospheric Pressure
Atmospheric Pressure in Earth AtmospheresAtmospheric Composition
Description of Atmopsheric CompositionAlbedo
Albedo is the proportion of energy reflected into space (between 0 and 1)Greenhouse Effect
The Greenhouse retention of heat by the atmosphere as a multipler (e.g. 1.05 = 5%)Axial Tilt (degrees)
Axial Tilt - used to calculate seasonal variationsBase World Temperature
The average temperature for the world calculated using stellar luminosity, distance from the star, greenhouse effect and albedo.Average Daytime Temperature
The base temperature plus the typical temperature rise caused by the sun during the day. The average daily maximum temperature.Average Nighttime Temperature
The base temperature minus the typical temperature fall during the night. The average nightly minimum temperature.Summer Increase
The maximum increase of temperature in summer when a hemisphere is tilted towards the parent star.Winter Decrease
The maximum decrease of temperature in winter when a hemisphere is tilted away from the parent star.Upper Temperature Limit
Daytime temperature plus summer increase.Lower Temperature Limit
Nighttime temperature minus winter decrease.Hydrographic Percentage
More precise percentage of planet covered in liquid.Surface Liquid Composition
Are you SURE that's water!?Native Life?
The world has or does not have native life. Regardless, the world may have imported species.Intelligent Life Status
Indication of the (Native) Intelligent Life on this world.Seismic Stress
Seismic Stress minus 4 is the daily chance on 4D for an earthquake, Mod +2 if on a fault line.Resources
The raw resources available to this world.Labor
A measure of the labor force available.Infrastructure
How sophisticated the infrastructure is.Efficiency
Impediments to or enablers of economic growth; negative efficiency means the world is a net importer.Heterogeneity
Higher is more culturally diverseAcceptance
Higher means a greater acceptance of outsidersStrangeness
Higher means more weirdSymbols
Lower means use of more concrete symbols; higher means more abstract symbols.General description
This way of looking at symbols taken from a post by Thomas Jones-Low found here. A general description of the culture.
