Description

Have fun learning how your solar system works according to Newton's laws of physics. You have full control over the sun and the planets. Change the behavior of the planets by modifying their mass, radius, or image. Increase the Sun's mass enough and a planet is sucked in, burned up, never to return. Be master of your own universe by adding new planets and experimenting with changes and possible catastrophes. Zoom in to see the orbit in more detail. Zoom out to see more planets including Jupiter. Turn on tracing and see the full orbits. Speed up or slow down the time factor to create interesting and entertaining designs. This is all made possible by using a custom physics engine developed over two years to accurately simulate the delicate movements of the planets. Orbits HD will greatly increase your understanding of the play between mass, momentum, and the gravitational pull of the Sun. Compatible with IOS 7.1+, and supports pause/continue. Answer a phone call, then return to the simulation in progress. Engaging and educational on the iPhone and iPad.

What's New in Version 5.2

There is now a moon orbiting the Earth. Bugs fixed. Now compatible with iPhone 6 and iPhone 6 plus.
