Thank you selden!! I will do some research on 'brown dwarf'!!

I am just wondering if it is possible for a natural system with a gas giant as the "star"? That means a systme basically has no sun light.

OK, its turn out that selden is right :D I found the following paragraph, http://science.nasa.gov/headlines/y2004/27sep_shieldsup.htm Its temperature, 6000 C, is about the same as the surface temperature of the sun. A spacecraft flying through the stream won't melt, though, or even notice the heat. ...
