>A new "Earth-like" planet! OMG it's going to be just like Earth! Let's all draw it that way!

No. This shit-hole is Tidally Locked. That means that its sun only shines on the same half of the planet all the time. This means no air currents, which are a byproduct of changing temperatures. No air currents also means no precipitation, even if there are fluids on the surface. Hell there probably isn't even an atmosphere.

This is one barren ass rock guys.

It does mean air currents. Really fucking strong ones.

> That means that its sun only shines on the same half of the planet all the time. This means no air currents, which are a byproduct of changing temperatures.

Actually the tidal locking would mean high-speed winds between the illuminated and the dark side, due to large temperature differences.
The atmosphere can not be ruled out yet.

It actually depends on its dynamical history, location of the snow line, availability of gas due to transport by external bodies (example: late heavy bombardment), outgassing, etc.

Lol no.

Surface heating -> convection -> if there is water vapor, condensation and precipitation

Because hot and cold air don't just leave each other alone. There will be extreme pressure differences where the temperature changes.

>>1882582
It's difficult to know it. The internal heat released due to radioactive decay has influence on presence of a liquid metallic core (and hence a strong enough magnetic field), tectonic activity, etc.

The thickness and composition of the atmosphere influences physical and chemical erosion, climate, etc.
Oceans, clouds and ice caps regulate albedo, energy transport and a shit-ton of other stuff.

We need spectroscopic data on that shit.

>> No.1882600

Doesn't the existance of two poles with large temperature differences create somesort of planetary convection wind? Huge masses of air going from one pole to another and vice versa? That would be freaky.

>> No.1882607

>>1882582
my immediate suspicion is that you'd have very severe weather patterns (at least, intense winds/surface activity) at the horizon. obviously everything outside of that narrow band would be completely uninhabitable.

physically, i'm thinking you'd have a massive ring vortex stretching all the way around the planet at the horizon.

but i'm just a 4th year grad student in aerodynamics...

Hot air will flow up toward the dark region and cold air would flow underneath toward the hot region. Intense wind.

I wonder if a locked planet could inhabited in the rim close to the dark, where the perpetual sun would be balanced by the cold winds.

Imagine the possibilities for wind power along the rim there.

You'll need really durable materials, but constant, powerful winds = reliable power output.

From my knowledge base, you are sounding pretty ignorant of the topic.
