Star Cooler Than Venus Found

crossconnects writes to mention that Discovery is reporting that astronomers have found a nearby star with a mild surface temperature of 660 degrees fahrenheit. "The spectacularly unspectacular object is of special interest because it falls right smack in the middle of the final frontier that divides mega-planets from the puniest stars. Stars in that realm theoretically qualify as an entirely new stellar type -- what's called a Y class dwarf."

Re:Nuclear fusion?

Stars above about 13 jupiter masses fuse deuterium and above 65 jupiter masses also fuse lithium, according to Wikipedia. Below 13 jupiter masses, well, it's hard to say...
