Gravity Simulator
Interactive Space Physics Sandbox In Your Browser
Explore gravity through two interactive physics engines built for experimentation and learning. Test how objects fall on different planets and moons with the Object Drop Engine, or create realistic orbital simulations featuring planetary motion, collisions, slingshots, and N-body gravity systems. Gravity Simulator runs entirely in the browser with real-time controls, cinematic visuals, and scientifically inspired physics - no downloads or installations required.
Hey Product Hunt 👋
I built Gravity Simulator to make gravity and orbital physics feel interactive instead of abstract.
Most online physics simulations are either too limited, visually outdated, or locked behind heavy desktop software. I wanted to create something that runs entirely in the browser while still feeling immersive, responsive, and scientifically inspired.
Gravity Simulator currently includes two interactive simulation engines:
🌍 Object Drop Engine: Test how gravity affects falling objects across planets and moons using different gravitational environments.
🪐 Orbital Gravity Simulator: Create and experiment with orbital systems, planetary motion, collisions, slingshots, and chaotic N-body interactions in real time.
The goal was to blend education, experimentation, and visual simulation into a single accessible platform for students, educators, creators, and space enthusiasts.
Some of the biggest challenges were balancing physics accuracy with browser performance, designing intuitive controls, and making the simulations feel visually cinematic while remaining interactive.
I’d genuinely love feedback from the PH community:
• What experiments would you want to try?
• Which features would make this more useful or fun?
• What celestial mechanics tools would you like to see next?
Thanks for checking it out 🚀

Who hunted Gravity Simulator?
Gravity Simulator was hunted by Aman Mathur. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
