Stars orbit around the galactic center due to the gravitational pull of the supermassive black hole located at the center of the galaxy. This gravitational force keeps the stars in their elliptical orbit around the center.
The direction of stars' orbits around the galactic center is determined by the initial conditions of the stars, including their position, velocity, and angular momentum. These initial conditions are influenced by the gravitational forces of nearby stars and gas clouds.
No, not all stars orbit in the same direction around the galactic center. The direction of a star's orbit depends on its initial conditions, so some stars may have a clockwise orbit while others have a counterclockwise orbit.
The time it takes for a star to complete one orbit around the galactic center varies depending on its distance from the center and its orbital speed. On average, it takes the Sun approximately 250 million years to complete one orbit around the Milky Way galaxy.
Yes, the direction of a star's orbit around the galactic center can change over time due to interactions with other stars or gravitational disturbances. However, these changes are usually gradual and may take millions of years to occur.
