How does the Milky Way galaxy move in the local Group? Is there a circular motion around the center of the local Group like the sun moves around the center of the galaxy?
The local Group is a group of galaxies that includes the Milky Way and Andromeda galaxies, as well as several smaller galaxies. It is the gravitationally bound region that these galaxies occupy within the larger universe.
The Milky Way moves within the local Group through a combination of its own motion and the gravitational pull of the other galaxies in the group. It is currently moving towards the Andromeda galaxy at a speed of approximately 110 kilometers per second.
Dark matter plays a significant role in the movement of the Milky Way within the local Group. It is believed that the majority of the mass in the local Group is made up of dark matter, and its gravitational pull helps to hold the galaxies together and influence their movement.
Scientists study the movement of the Milky Way within the local Group through various methods, including observations of the positions and velocities of other galaxies within the group, computer simulations, and studying the effects of gravitational interactions between the galaxies.
Yes, it is predicted that the Milky Way will eventually collide with the Andromeda galaxy in approximately 4.5 billion years. This collision will result in the formation of a new, larger galaxy known as Milkomeda.
