Animation
The animation above shows how a halo orbit looks from above in an inertial frame. The blue sphere is the Earth, the yellow sphere is the Moon, the red line is the Moon's orbit, and the turquoise line is the halo orbit. It is basically an orbit about the Earth that stays on the far side of the Moon and plays an orbital game of "Crack-the-Whip" with the Moon.
Animation
This animation shows how a halo orbit looks from above in a coordinate frame that rotates with the Earth and Moon, so they appear to hold stationary. The blue sphere is the Earth, the gray sphere is the Moon, and the two red spheres are the Lagrange points L1 and L2. The spacecraft is orbiting near the L2 point.
