The Kamehameha Wave

Extra credit: Knowing a Kamehameha wave travels at half the speed of light, and that 1 light-minute equals 1/10 of an AU, how long would it take for the blast to reach the sun?

Goku can fly, so the time depends on how far he is from the sun. Also, he protects the Earth, so he'd never destroy the sun.
