Planets are suddenly too cold

[SapphireCarbuncle]

It appears that since 19 x8, even planets in a star's red zone tend to have temperatures below zero if their albedoes are non-zero. Is this a bug or a feature?

probably a bug

[Dan Dixon]

Sounds like a bug. Thanks for reporting this. We'll look into it.

[SapphireCarbuncle]

like, if a planet is placed at sqrt(luminosity in sols) AU from its star and is given an albedo of 0.31, its effective temperature is always -16.5, even with a super-thick atmosphere (in fact, thicker atmospheres speed up cooling).

I'm having trouble duplicating this issue...

Can you write out the exact steps I need to take to make this happen (something like this):

- Open Solar System
- Turn on Habitable Zone
- Add Mercury at ~0.3au
- Select Mercury
- In the temperature tab, change Albedo to 0.31

[SapphireCarbuncle]

I've added the sun, and I placed 3 mercuries at 0.3, 0.6 and 1 AU.
Mercury 1 (0.3 AU): 466 K
Mercury 2 (0.6 AU): 331 K
Mercury 3 (1 AU, Earth's orbit): 257 K (-16.5)
Note that neither planet size nor atmospheric pressure affect the effective temperature. I've tried that, it does nothing.

I've had this ever since the second update to Alpha 19 preview... Greenhouse effect not being calculated to surface tempeture.

Edit: Forgot to mention, that this effects all non-premade objects, which means All random rocky planets, all random moons etc.
