Asteroid Launcher - Free Unblocked Impact Simulation
Asteroid Launcher is a scientifically grounded browser game created by Neal Agarwal as part of the Neal.fun project. It lets you choose an asteroid - from a modest house-sized rock to a city-destroying behemoth - select a target anywhere on Earth, and watch a real-time simulation of the aftermath. Crater diameters, blast radii, energy released in megatons of TNT, and the scale of destruction are all computed from actual astrophysics models.
Play it here for free, unblocked, with no download or account required. Works instantly on desktop and mobile.
How to Play
- Click Play Now to load the simulation in your browser - it starts in seconds.
- Choose your asteroid - select size (from 25 metres to 500+ km) and rock composition.
- Pick a target - click anywhere on the interactive Earth map to set your impact location.
- Launch - watch the simulation calculate and visualise the impact: crater size, fireball radius, shockwave range, and more.
- Compare impacts - try different asteroids and locations to understand what scale of space rock actually poses a civilisation-level threat.
What Makes It Special
Unlike most browser games, Asteroid Launcher isn't about reflexes or points - it's a genuine scientific tool dressed up as entertainment. Every number you see is derived from published planetary science research. The simulation accounts for asteroid density and composition (rocky vs. iron), entry angle, and the target's geography.
The game puts cosmic scale into visceral human terms: a 500-metre asteroid strike on a major city isn't just "big" - the simulation tells you exactly how many kilometres of total destruction you're looking at. That kind of perspective is rare, memorable, and genuinely educational.
