Using a complex orbit of multiple objects

The simulation scenario allows for easily adding more objects with varied orbit patterns.

How to do it...

We can use a script like this:

import rebound

# setup simulation
sim = rebound.Simulation()
sim.getWidget()

# add star
sim.add(m=1)

# add ten 'planets'
for i in range(10):
 sim.add(m=1e-3, a=0.4+0.1*i, inc=0.03*i, omega=5.*i)

# center all particles
sim.move_to_com()

# advance the simulation
sim.integrate(500)

# get our final display on screen
fig = rebound.OrbitPlot(sim)
fig

This results in a display like:

How it works...

Just as with the simpler case, we start a simulation. Then, in this case, we add a couple of objects. Each of the objects has a complex orbit about the star. We advance the clock by hundreds of cycles with sim.integrate(500) to gather a complete picture, and we display the results.
