The Planet Eater

From the Back of the Book As a Space Hawk, you've gone up against some of the most deadly enemies in the solar system. But you've never faced an opponent as awesome as Nemesis. This all-powerful alien, with its 400,000-mile-long spaceship, devours any planet in its path--and Earth is next. It's a challenge only the Space Hawks can meet--or can they? Unless the Space Hawks can overcome Nemesis, Earth is doomed!
