OK, one problem is that our solar system is tilted 90 degrees to the galaxial plane. Like if you took a quarter and stood it on edge on top of another quarter. So not only are we at a 90 degree angle but we're also oscillating up and down through the galaxial plane, putting a lot of variables into play here.
EXPLANATION OF THE MODEL:
It is not simple to position of our Solar System with respect to the Plane of the galaxy -the Milky Way. There are few books of Astronomy screening a diagram of the coplanarity of the Solar System with the galaxy, so we regularly think that what is "up" or north for the Earth it is also "up" or north for the galaxy. However, the plane of the Solar System is not coplanar with the plane of the Milky Way, but it is tilted almost 90°.
The Solar System describes three kinds of motion, each one at a specific speed and with a limited alternation:
1. The wider and fastest movement is the orbital motion of the Solar System around the nucleus of our galaxy. The speed of the Solar System orbital motion around the center of the galaxy is 217.215 Km/s. The Solar System completes one track around the galaxy each ~226 million years.
2. The second movement, described in most of astronomy books, is the oscillation of the Solar System from north to south and vice versa with respect to the galactic plane. It is a swing upwards and downwards, determined mainly by the gravitational pull among the celestial bodies in the Solar System. The speed of this movement is of 7 Km/second.
3. The third movement is in route towards the center of the galaxy and the order reversed or moving away from the center of the galaxy. It is also a swinging movement, but influenced by the gravitational pull of outer and inner celestial bodies of the galaxy that are near to the Solar System. This motion has a speed of 20 Km/s, and it is drawing now toward Hercules constellation.
