Solid. Everything except hydrogen and helium would be in a solid state I think.

That’s not obvious because of the ultra low pressure.

Agreed. I haven’t thought about this stuff since taking gen chem in college, so I went and looked up the phase diagram for Neon, as an example.

At low pressures, it looks like as little as 15 Kelvin is enough to make Neon a gas.

However, deep space is 2.7 Kelvin. Though of course it gets much hotter near stars and even simply being inside a galaxy is enough to hit 10-20 Kelvin.
