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?

Hi. I last read 240,000,000 years or so. From the web "It takes the Solar System about 225–250 million years to complete one orbit " http://en.wikipedia.org/wiki/Milky_Way

Based on current observations from various instruments, the best calculation is an estimate of between 225 million and 250 million years.
