Radius - 3 x 1018 m

The Virgo Cluster of galaxies, which includes the Milky Way, has a radius of approximately 8 x 1023 m Distances become so large when describing astronomical terms that other units are used, such as a light year and a parsec. 1 parsec is equal to about 3. 26 light years (3. 086 × 1016 m) Largest commonly used prefix is a gigaparsec. 1 Gpc = 3 x 1025 m
