How long does it take our solar system to make an orbit around the Milky Way?

Filed Under bookcases 

miyuki & kyojin asked:


I was looking in several astronomy books in my bookcases, and I see different figures given for the amount of time it takes our Sun and its family of planets, asteroids, etc. to travel once around our galaxy. some of my books are old, while others are new. Does anyone know the latest estimate?

      The best calculation is an estimate of between 225 million years.
