Orbit Xplorer

Physics educational software for high school, college and university students and teachers. May also be of interest to the amateur astronomer and physicist. With Orbit Xplorer orbit simulator you can do lab exercises in gravitational physics. Study elliptical orbits, double stars, escape velocity, Keplers third law, Lagrange points, the three-body problem and more.
Educational orbit and gravitation simulator for high school, college and beginning university physics and astronomy. Input mass, radius, coordinates and velocity components of 2 to 10 bodies manually or by dragging and dropping predefined bodies. Then watch how the orbits evolve under the mutual gravitaional attractions. Save and print the simulation.
Great for lab exercises in gravitational physics or for verifying numerical answers to textbook problems.
Includes 29 introductory to advanced premade simulations with activities page in html-format. The simulations provided with Orbit Xplorer include geocentric and heliocentric world view, elliptical satellite orbits, gravity assist, Keplers laws, double star, Lagrange points, Hohmann orbit, inner solar system, extrasolar planet. Uses actual pictures of planets.
Plot orbits in a plane or in 3D. View time, distances, speeds, accelerations, energies and acceleration vectors as they change. Adjust the simulation speed to fit your computer. Zoom and change parameters during the simulation. Run up to four simultaneous simulations.
With Orbit Xplorer orbit simulator you may:
Calculate and plot the orbits of up to 10 gravitationally interacting bodies.
Easily create, run, save and print your own orbit simulation.
View time, distance, velocity, acceleration and energy.
Create graphs of distance, velocity, acceleration and energy versus time.
Run up to four simultaneous simulations.
