On a website it is written as 225 million years, but mostly 230 million years is written out on others. 250million years must be the wrong answer. Please confirm before updating
answer updated to 230 but actually it is about 225 to 250. The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. Estimates of the length of one orbit range from 225 to 250 million terrestrial years.
