The galactic year, also known as a cosmic year, is the duration of time required for the solar system to orbit once around the centre of the Milky Way galaxy. Estimates of the length of one orbit range from 225 to 250 million "terrestrial" years.
This means "we" have been around the centre of our Galaxy, only 20 times.
Estimates place the speed of rotation at approximately 230 kilometers a second, or 828,000kph (515,000 mph)
