Answer:

225 -250 million Earth-years

Explanation:

A galactic year or cosmic year is the time it takes for the Sun (and the solar system) to make an orbit around the center of the galaxy (Milky Way). The solar system travels at a speed of 828,000 Kilometers per hour (230 [tex]\frac{km}{s}[/tex]).

 So the time it takes to make this turn, measured in Earth years, should be between 225 and 250 million years.
