# I made a graph trying to show the Sun's movement relative to the Galactic Plane. It doesn't seem to be correct

I made a Desmos Graph following the most voted answer of this question, but I'm not sure if it is correct, because it suggest that the formation of the Sun happened shortly after it would have crossed the galactic plane, but the Sun did not exist before that. Is that possible?

• First, your $x$ is wrong. The universe isn't even $\sim 57$ billion years old. Please edit your question to correct it. – fasterthanlight May 28 at 0:28
• Probably not. The sun is executing radial epicyclic motion around the galactic center, so its distance increases and decreases periodically. The question you are referring to does not say anything about radial motion, so anything you have plotted on that basis must be wrong. – AtmosphericPrisonEscape May 28 at 0:34

• @fasterthanlight ok, but where is the Sun now? if I mark x=4.6*10^9 the graph show that the Sun is going down, towards the galactic plane, where the post I mentioned states that the Sun is currently going up. – Zeniel Danaku May 28 at 1:16
• @fasterthanlight again, and I quote "As the Sun is currently above the plane and moving upwards, and each cycle takes about 70 million years with an amplitude of 100pc, it will be roughly 30 million years before we cross the plane again" The "correction" you made marks the sun as going down. – Zeniel Danaku May 28 at 1:48
