Nasa Finds Chilled Out Star This is reportedly the "coolest" star ever found, with a surface temperature of 80 degrees Fahrenheit. I'm not up on all the details here, but I find myself wondering if a star like that could be colonized directly. If the surface temp is 80 degrees, why not build something on the surface? The biggest issue I think would exist would be Gravity. I find myself wondering what the gravitational force is that is acting on a person on the surface. Otherwise, wow. Imagine having a home on the surface of the star.
