The orbit takes about 225 million years and the Sun has completed about 21 such orbits during its 4.5 billion year life.
Or as Eric Idle once sung…
Just remember that you’re standing on a planet that’s evolving
And revolving at nine hundred miles an hour,
That’s orbiting at nineteen miles a second, so it’s reckoned,
A sun that is the source of all our power.
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour,
Of the galaxy we call the “Milky Way”.
Our galaxy itself contains a hundred billion stars.
It’s a hundred thousand light years side to side.
It bulges in the middle, sixteen thousand light years thick,
But out by us, it’s just three thousand light years wide.
We’re thirty thousand light years from galactic central point.
We go ’round every two hundred million years,
And our galaxy is only one of millions of billions
In this amazing and expanding universe.
I think about this and laugh when people don’t want to travel. The most traveled person on earth and the least traveled are within .00001% (I made that up) margin of difference.
We are all travelers.
