Asteroid Hazard is a space strategy game based on real orbital mechanics. Asteroids, comets, and interstellar objects are hurtling toward Earth. You have launch vehicles, interceptors equipped with optical guidance systems, and time — but not much of it. What sets this game apart from the rest: → Real Keplerian orbits. Every trajectory follows Newton’s laws. → The real Solar System—from Mercury to Neptune. → Optical guidance locks onto the target and corrects the interceptor’s course—just like in real interplanetary space missions. → Three classes of threats: asteroids, comets, and interstellar objects—each with its own orbital patterns and interception difficulty. → Upgrade system: interceptor launch frequency, intercept speed and range, optical tracking system improvements, number of simultaneously launched spacecraft, and threat detection system enhancements. → Cross-platform leaderboard: compete with friends and dangerous asteroid hunters around the world This isn’t a toy solar system. It’s a simulation created by a scientist who has discovered 6 comets and over 500 asteroids, including those approaching Earth. Can you defend the planet?
