Science Fiction Blue Mystery Suspense Book Cover Ideas with Sky Moon Danger Planet Asteroid

A serene and expansive blue sky forms the backdrop, dominated by a large, mysterious watery planet taking up the lower half of the cover. A glowing moon hovers in the top right corner, while a larger neighboring planet with faint rings sits majestically in the top left, its shadows cast subtly across the sky. In the middle-ground, an ominous asteroid hurtles diagonally across the scene, emanating a trail of glowing particles, hinting at its impending collision with the planet. The scene encapsulates suspense, danger, and mystery, with sharp contrasts between the tranquil planet and the threatening asteroid.

The book title, "Collision Course," is in a bold, futuristic sans-serif font with a metallic sheen, situated centrally at the top. The author's name, "Dawn Steinman," is placed at the bottom in a sleek, modern serif font, tinted slightly in silver to reflect the celestial theme.

The cover is divided into thirds - the top third is mainly sky and planets, the middle features the asteroid, and the bottom hosts the author’s name against the eerie vastness of the watery planet. The title is prominently centered, drawing immediate attention, while the celestial components surround it.
