On a more terrestrial basis, our home galaxy is larger than 587,862,540,000,000,000 miles.
When the Milky Way and Andromeda eventually collided, astronomers calculated that the collision would produce an even larger cluster of stars.
The product of this galactic collision is called Milcomeda.
Astronomers from the European Space Agency (ESA) said: “Our own Milky Way contains the wreckage of much smaller galaxies that it has encountered and swallowed in the past, and is currently being swallowed by the elliptical galaxy Dwarf Sagittarius.
In turn, it seems that our Milky Way will be included in its giant neighbor, the galaxy Andromeda, resulting in an elliptical galaxy called Milcomeda, the new home for the Earth, the Sun and the rest of the solar system for about two billion years. “
