Our place in the universe

Everything that has been, everything we know, everything that will be, happens on a planet known as the Earth. We think that it is the only planet that has life on it, but we could be wrong. The Earth is part of a vast interplanetary system stretching around 8 388 511 095 miles across. Our Solar system has eight planets, as well the possibility of several hundred Dwarf planets with five currently recognized. In addition to this, it has about 707,664 minor planets. Furthermore, it has 462 natural satellites. Along with 3 460 known comets. And still, it is all a speck amid across the interstellar voids that we share with others 100 billion stars in a galaxy that we call the Milky Way, which we find in the Local Interstellar Cloud. This cloud is in the Gould Belt that in turn lies in the Orion Arm. Now, the Milky Way is in the Local Group that is a cluster of galaxies which have about a dozen other galaxies. Currently, all of this is part of the Virgo Supercluster that contains thousands of clusters of galaxies, including the Local Group as one of its smaller members. All this is in the Laniakea Supercluster. And still, the universe extends to infinity. Though we know how it got here after a Big Bang that happened about 13.799 billion years ago, all this makes one simple conclusion: That we all are stardust that is all interconnected to each other biologically, to the Earth chemically, and to the rest of the Universe atomically.
