Planetary environments are categorised by the combination of the planet's climate (hot, temperate and cold) and type of atmosphere (toxic, breathable and absent/none). There is an additional category to the various combinations of the above, 'Gas Giant', which covers both the atmosphere and the climate.

The images you will see while ascending/descending to/from atmosphere on the various bodies can be viewed in the Planets Rules page.

The following table shows the amount of damage a character receives if unprotected in an hostile environment. This damage is only applied when you are outside and exposed to the elements, ie: not in a city. Upon reaching 0 HP an unprotected character will fall into unconsciousness and cease to receive environmental damage.

Planet Type	Damage
Hot No Atmos	30%
Hot Toxic	15%
Hot Breathable	5%
Temperate Breathable	None
Cold Breathable	5%
Cold Toxic	15%
Cold No Atmos	30%
Gas Giant	15%
Sun	Dead*
Moon	None
Asteroid	30%
Comet	Dead*
Blackhole	Dead*

Environmental damage is taken on your current HP every 60 minutes.

*See Sun & Black Holes Damage Rules.
