Gravity Plus电脑版

Play with planetary orbits in this fun exciting space physics sandbox. Try to make a solar system full of asteroids, moons, planets, and suns. Touch the screen to add a planet. Drag your finger across the screen to give a planet a little bit of velocity. Enough speed will cause your planet to orbit. When planets collide, they combine together into a larger planet. At certain sizes, objects change color to indicate a different type of object: sun, planet, asteroid, etc. A Great Physics Sandbox Game!
