The Heliocentric System is a cosmological model which states that the location of the Sun is near central point and celestial bodies like planets, comets, and asteroids revolve around it.

Putting the Sun at the center of our Solar System, other astronomers began to realize, simplified the orbits for the planets. And it helped explain what was so weird about Mars.

The impressive cosmic model measures 1.5 meters across, and is believed to be the first model of its kind to represent the motions of our Solar System’s planets and moons in a heliocentric model.

With those numbers, Dr. Quarta solved 180 different optimal control thrust vector problems using either 1, 2, or 3 ion thrusters, for heliocentric orbits between .85 AU and 1.15 AU.
