Orbits

Gravity and Orbits is a a Java application designed to enable you to investigate the forces that affect planets. Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies,...

The Ejs N-body Orbits model displays the dynamics of three to five identical masses orbiting each other subject to Newtonian gravity. The simulation displays the periodic orbital motion of the masses. The initial configuration of the system can be changed via slider. You can modify this...

The Orbits Within Spherical Galaxies model displays the two-dimensional trajectories of particles (stars) within a galaxy having a spherically symmetric mass distribution that heuristically approximates the distributions found in galaxies and bulges. The model uses a mass density proposed by...

The EJS Ballistics and Orbits model displays ballistic trajectories near the Earth. The model shows the trajectory with respect to the inertial coordinate system and the trajectory as seen from a point of view that is co-rotating with the Earth. You can examine and modify this simulation if you...

Planet's Orbits (for Windows 98/ME/2000/XP) is an accurate digital orrery with a wealth of functionality. The program uses the DE404 ephemeris (accurate for dates between 2000 B.C. and 6000 AD) for the calculation of planetary (except Pluto) and lunar positions. The calculation of the positions...

Simulates the motion of a single planet in a binary star solar system. Uses Simulink to solve the equation of motion for the planet. The stars are assumed to be stationary. Have fun changing the system parameters to generate strange orbits!


Platforms: Matlab

By entering the appropriate orbital elements, you can plot the orbit around a 3D view of Earth. The funcion also allows for click-and-drag camera manipulation. You can also do a fly-by.Enjoy!
