Orbit Simulator
Place planets around a star and drag their launch velocity to shape the orbit. A dashed path shows where each one is heading. Too slow and it falls in, too fast and it escapes. Turn on mutual gravity to see bodies pull on each other.
What you can do
- Up to six bodies, each with a draggable launch velocity
- A predicted path for each orbit, bound or escaping
- Live speed, distance, period and eccentricity
- Set circular or escape speed with one press
- Ready-made scenes, including a planet with a moon
