Galaxy
The Whirlpool Galaxy (left), also known as M51, an Sc galaxy accompanied by a small irregular companion galaxy, NGC 5195 (right).
The solar system orbits the center of the Milky Way Galaxy at a velocity of approximately 828,000 kilometers per hour (about 225–230 kilometers per second).12
This orbital journey is estimated to take roughly 225 to 240 million years to complete, a duration often referred to as a cosmic year. While these figures are widely accepted, it is important to note that the exact speed can vary based on the specific measurement methods and models used by astronomers to account for the galaxy's rotation and the distribution of dark matter.123
