We live in a rocky planet — Earth — orbiting the center of mass of our Solar System every about 365 terrestrial days.
The single star of our Solar System is the Sun, a middle-aged ordinary galactic star.
Our star the Sun is just one of the hundreds billions stars of our galaxy, the Milky Way.
Our Galaxy is a spiral of moderate mass, and we live in one of its outer spiral arms.
Together with the Sun and the other planets and bodies of the Solar System, we travel around the Milky Way’s center every about 200-220 million terrestrial years.
Our Galaxy is a solitary one. Our closest neighbor is Andromeda, a spiral galaxy 2.5 million light years from Earth, very much similar to the Milky Way.
Andromeda and the Milky Way are going to merge in about 4500 million terrestrial years, giving existence to a larger single galaxy.
This future larger galaxy will continue its cosmic journey and will eventually merge with other thousands galaxies in the immense Virgo Cluster; and the cosmic journey will go on.
We all live in the same tiny space rock.
We are all cosmic beings.
