Rikki Tikki Traveller said:Roasting is just inside the habitable zone (like Venus) and Freezing is just outside the habitable zone (like Mars). Farther out is not really detailed yet in Mongoose Traveller.
Not necessarily. "Freezing" might have to be outside the Habitable Zone, but a world in the Habitable Zone can easily be "Roasting" if it has a thick greenhouse atmosphere like Venus.
Or you could have a planet on an eccentric orbit that swings between the two extremes.
And vacuum worlds will be alternately Roasting and Freezing on their day and night sides since they have no atmosphere. Our own Moon goes from a maximum of about 120°C on its dayside to -200°C on the nightside. I did suggest an "E" (for Extreme) temperature code to reflect this, but I guess that didn't make the final cut.
