A simple interactive program for playing with simulations of planetary systems, released under the GPL. #Solar system simulator #Planetary system simulation #Planet simulator #Simulate #Simulator #Simulation
Planets runs on Windows and Linux, and could doubtless be ported to your favorite flavor of Unix.
Planets was originally designed for kids, in particular, for a 4-year old nephew who is fascinated by astronomy.
The user interface is aimed at being simple enough that a fairly young kid can get some joy out of it. But the adults who have used it have found it to be pretty fun as well.
Here are some key features of "Planets":
■ Saving and loading of universes ■ Infinite undo (erase last action) and goback (return to point in time just after last action). This allows for undoing mistakes and replaying interesting configurations. ■ Traces of planet trajectories ■ Two ways of dealing with planet collisions: ■ merges, where the colliding planets are merged into one planet, and ■ bounces, where the colliding planets are bounced off each other elastically. This itself comes in two varieties: ■ force bouncing, where the force between planets is made repulsive at close quarters. ■ true bouncing, where simple pool-table physics calculations are made to determine when planets collide, and compute the appropriate bounce from said collision. ■ kidmode, a mode where the focus is (mostly) locked on the application, and interesting changes are initiated by merely banging on the keyboard. This mode is aimed at 1-5 year olds. ■ Center-of-mass following: it is possible to follow the center of mass of a subset of the planets. Thus, if you have a sun-moon-planet system, you can have the view automatically track the moon-planet pair. ■ Can display kinetic, potential and total energy of the system. ■ Both the gravitational constant and the gravitational exponent can be changed. ■ There is a simple control panel that makes it possible to see and change the simulation options. ■ Zooming, panning, and centering on the center of mass
Requirements:
■ Tcl version 8.3
