WebJun 27, 2024 · [ Recent measurements on the size of the Milky Way using the VLBA have scaled the distances and speeds up---the Sun's distance from the center is 8.15 kpc and the circular rotation speed at the Sun's position is 236 km/sec---but how the speeds change with distance, the shape of the rotation curve, is still as described here.] 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. One galactic year is 230 million Earth years. The Solar System is traveling at an average speed of 230 km/s (828,000 km/h) or 143 mi/s (514,000 mph) within its trajectory around the galactic center, a speed at which an object could circumn…
