* No central point: Unlike planets orbiting a star, galaxies don't orbit a single, massive object.
* Gravitational interaction: Galaxies are held together by the collective gravity of all the stars, gas, dust, and dark matter within them. They also interact gravitationally with other galaxies in their local group.
* Movement within groups: Galaxies in a group or cluster tend to move around each other, influenced by their mutual gravitational pull. Think of them like a cosmic dance, constantly shifting and interacting.
* Expansion of the universe: On a larger scale, the universe is expanding. This means that galaxies are moving further apart from each other.
So, the Milky Way doesn't orbit anything specific, but it does move within the local group of galaxies and participates in the overall expansion of the universe.
