# Best approximation for Sun's trajectory around galactic center?

What is the current best approximation for the path the Sun takes around the center of the Milky Way?

I have found some information on the approximate position of the Milky Way's center, the speed of the Sun's orbit, and the inclination/declination of the Sun's orbit. I have also seen models suggesting the Solar System oscillates up and down as it revolves around the galactic center.

I am wondering if there is any agreed upon approximation (a 3d plot of position vs time) that includes all of these factors.

The Sun orbits in the Galactic potential. The motion is complex; it takes about 230 million years to make a circuit with an orbital speed of around 220 km/s, but at the same time it oscillates up and down with respect to the Galactic plane every $\sim 70$ million years and also wobbles in and out every $\sim 150$ million years (this is called epicyclic motion). The spatial amplitudes of these oscillations are around 100 pc vertically and 300 pc in the radial direction inwards and outwards around an average orbital radius (I am unable to locate a precise figure for the latter).
• To an anonymous user who made a comment and a non-edit to my answer: The ~300pc radial oscillation in ~150 million years means an average in-out oscillation speed of a few km/s; perfectly compatible with the currently understood $U$ velocity of the Sun wrt the local standard of rest. – ProfRob Sep 15 '16 at 13:45
