Just wanted to make a thread where people can ask theoretical questions and see if anyone can answer them.

My question is this.

What would happen on the dark side of an exoplanet(that is what any planet that is not orbiting OUR Sun is called) that was orbiting so close to its star, that the sun could make its surface molten and it was in the same fashion that the Moon orbits earth? By this I mean a permanent dark and light side. The rotation just happens to be at exactly the right amount so that the suns light would only ever see one side. What would that dark side be like?

I guess it would depend IMHO if there was an atmosphere or not

there is a known exoplanet that is said to be close enough to it's sun that IIRC the winds travel about mach 15 from the day side to the the night side & the winds are superheated

Let's assume there was. I was told such a planet would start to look a little like a teardrop as the molten bits going into the atmosphere and accreting on the dark side. Or it would melt apart like a snowball. Over very long timeframes of course. Those were two quick theories tossed out by my Geology professor.
