WebOnce the heliocentric transfer orbit has been selected, we next determine the spacecraft's velocity relative to Earth. The relative velocity, which we will define as the vector v s/p , is the difference between the spacecraft's heliocentric velocity, v s , and the planet's orbital velocity, v p (see Figure 5.10). WebThis was before people understood about the forces of gravity and celestial motion. This became known as the GEOCENTRIC theory (things that start with 'geo' are to do with earth, things that start with 'helio' are to do with the sun). This problem with the geocentric theory is that it was wrong. Some ancient astronomers such as Aristarchus of ...
