Plotting help! Time is of the essence

[scidam]

You can try to continue with the following piece of code:

i

mport matplotlib.pyplot as plt
# ---------- Constants ----------
SCALE = 10**6
EARTH_RADIUS  = 6378000 / SCALE
MOON_RADIUS = 1737000 / SCALE
MOON_DIST = 384e6 / SCALE
# -------------------------------

fig = plt.figure()
ax = fig.add_subplot(111)
Earth = plt.Circle((0, 0), EARTH_RADIUS, color='g', label = 'Earth')
Moon = plt.Circle((0, MOON_DIST), MOON_RADIUS, color ='r', label='Moon')
ax.add_artist(Moon)
ax.add_artist(Earth)
plt.xlabel('x-position (Mm)')
plt.ylabel('y-position (Mm)')
plt.xlim(-10 ** 7 / SCALE, 10**8 / SCALE)
plt.ylim(-10 ** 7 / SCALE, 4* 10**8 / SCALE)
ax.set_aspect('equal')
plt.grid()
plt.show()

AFAIK, Matplotlib is designed to make publication ready figures. It is possible to create
animation using Matplotlib, but it is not primarily designed for this.
