Sandwiched between Hydra-Centaurus and Pavo-Indus, the Virgo Supercluster, one of several lobes of one of several million larger superclusters in the observable universe, spans around 110 million light-years in diameter.
On the outskirts of this supercluster, in a short filament extending from the Fornax to the Virgo Cluster, lies the Local Group, whose volume is very approximately one seven-thousandth that of the Virgo Supercluster.
Accounting for a mere one fifteen-millionth of the Local Group’s size, the Milky Way contains 200-400 billion identifiable stars and over 100 billion planets within the 100,000-120,000 light-years of its boundaries.
Orbiting this galaxy’s center once every 220-250 million years, at around 828,000 km/h, is a relatively infinitesimal yellow star.
Held in this star’s gravitational field, and about 1,300,000 times less voluminous, is a gas covered blue-green planet whose dominant carbon-based life forms still largely believe that this whole universe was specifically designed for the sole purpose of having them in it.
