Simulate Solar Orbit in Python

The repo includes three implementations of simulation.

1. File solar_orbit_2d.py plot the 2d orbit with Matplotlib
2. File solar_orbit_3d_plt.py plot the 3d orbit with Matplotlib3d
3. File 'solar_orbit_3d_ipyvolume.py' plot 3d orbit with ipyvolume
4. File 'three_body.py' simulate a three body orbit
