"Planet Gravity - Newtons law" is a physics-based simulation game available on Android. The game allows players to simulate asteroids flying through space and create their own solar system. With each level, the game presents new missions for players to complete, making it an engaging and interesting way to pass the time.

This sandbox-style game is focused on object gravity simulation and aims to increase the player's interest in the universe. However, the game does not provide any information about the developer or licensing information. If you're interested in creating your own universe freely, the game suggests two other options, "myDream Universe" and "Sandbox Planet," which can be found on the Appstore.
