    The Earth orbits the sun, it takes the sun between 225 and 250 million Earth years.

    One journey of our sun and planets around the center of our Milky Way galaxy is sometimes called a cosmic year. That’s approximately 225-250 million Earth-years

    A bit over 225 million years, Revolution varies a bit each time.

    Our solar system travels in a sinusoidal wave around the Milky Way. Best guesstimate, 250 million years which matches the Permian-Triassic extinction aka great dying.

    225,000,000 to 260,000,00. years for one revolution, NOT rotation. Different sources give different ranges.

    About 240 million years.

    About two hundred million years.

    Considering that anything remotely human has only been in existence for less than a million years, it gives you an insight into the gulf of  "deep time".
