Goku can't even survive without oxygen to breathe. Even if his body could survive the heat, gravity, and radiation of the sun (which is highly, highly unlikely), he would die from his lungs being filled with million - degree plasma.
Brad, you need to understand what "canon" means. If something is non - canon, it doesn't count. It never happened. It's no more usable than fanfiction.
DBZ characters are not anywhere near lightspeed, except the ones who can teleport (and that's not really speed, anyway). The best speed feat that is quantifiable is Gotenks flying to Buu's house somewhere else on the planet in 1 minute. If we generously assume that it was on the other side of the earth, then he can move at about mach 1000. That's very impressive, but not near lightspeed. Even at the very end of the manga, Super Buu w/Gohan absorbed (the second strongest character in the entire series) took so long to fly to Goku and Vegeta's location somewhere else on earth that Goku, Vegeta, and Baba had time to have an entire conversation where Goku convinced Vegeta to fuse with him before Buu got there. Light can circle the earth over 7 times in one second.
