Some info about our Galaxy
All the stars in the Milky Way orbit around a supermassive black hole at the center of the galaxy, which is estimated to be four million times more massive than our own. Luckily, it’s a safe distance from Earth, about 28,000 light-years. Our galaxy (100,000 light-years in diameter) is one of countless billions in the universe, each with millions, or more frequently billions, of its own stars. The Milky Way winds along a one-galactic orbit average speed of approximately 828,000 km/h. Our solar system takes about 230 million years to complete one revolution around the galactic center.
The local group
Our Galaxy is part of the Local Groupa “neighborhood” of about 10 million light years, made up of over 30 galaxies that are gravitationally linked to each other. Aside from our own galaxy, the largest of this group is which is on course with the Milky Way (about four billion years old). There Milky Way for the Greeks it represented milk lost by Hera while breastfeeding Hercules, which spilled and spread across the sky. Hercules, in fact, was the son of Zeus and of the mortal Alcmena who, for fear of retaliation from the wife of the king of the gods, abandoned him immediately after his birth. .
