Kerbol, also known as "the sun", is a main sequence G2 (yellow dwarf) type star and is home to the Kerbol System, Kerbin, and Kermanity.
"The Sun is the most well known object in the daytime sky. Scientists have noted a particular burning sensation and potential loss of vision if it is stared at for long periods of time. This is especially important to keep in mind considering the effect shiny objects have on the average Kerbal."
