Milky Way Galaxy
The Milky Way Galaxy as seen from Earth.
The Sun orbits the center of the Milky Way Galaxy at an orbital speed of approximately 220 to 225 kilometers per second.12
While these figures are commonly cited in astronomical studies, it is important to note that the exact value is not firmly established and can vary based on the methods used for measurement. This orbital motion is distinct from the Sun's movement relative to its neighboring stars or its velocity relative to the universe at large. At this speed, the Sun completes a full circuit around the galactic center approximately every 225 to 240 million years.312
