George O. Smith 
Troubled Star 

An advanced alien race is considering our sun as a reference point on their star route, but must first determine if there are any intelligent life-forms in its solar system, since altering the sun would be fatal for all the system’s life. The aliens seek to contact the most highly-regarded being on planet Earth, coming up with Dusty Britton of the Space Patrol. What they DON’T realize is that he’s an actor, star of a hit sci-fi TV show! Egotistical Dusty quickly realizes that he must now play his TV role in real life in order to save the solar system from disaster. An excellent mix of space opera, humor, and suspense! (Goodreads)
