Asteroid Hazard
Defend Earth!
Only for iPhone

Real cosmos. Real physics. Real threat. Built by a real astronomer.
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?
The first major update for Asteroid Hazard! You asked for it, and I listened: introducing version 1.1.0 — an update that makes everything more convenient!
What’s New:
- Asteroid orbit filtering: display only the orbits that are important to you at any given moment;
- Quickly view the interceptor(s) that have locked a target — very convenient;
- Switch between targeting modes: with or without tracking — whichever you prefer;
- Zoom control buttons — for comfortable one-handed gameplay;
- Comets and interstellar objects now show their direction of travel — no need to zoom out;
- Asteroids flash to warn you that they’re about to disappear;
- New online leaderboards: compete for the title of best hunter of the week and month;
- And, of course, an updated tutorial system — it’s now more detailed and intuitive!
In addition, all detected bugs have been sent on indefinite unpaid vacation.
In a word — Convenient!
Happy hunting!
