Viewed from the Galactic North Pole, the Milky Way galaxy is moving anticlockwise.
It is very easy. Since the Earth is in the Milky Way, you don't even have to move to get to the Milky Way.
They don't specifically orbit the black hole. Stars orbit the Milky Way because in general, they are attracted to the other masses in the Milky Way. The supermassive black hole is only a tiny fraction of the total mass of the Milky Way. Well, you might say that they move around the black hole, but that's only because it happens to be there. Without they black hole, they would move around the center of the Milky Way anyway.
We are in the Milky Way. It is in the sky all around us.
All of them. We are inside the Milky Way; the Milky Way is all around us.
Sort of. But please note that: (1) Moving around another object is called "revolving", or "orbiting", but not "rotating". (2) Planets move primarily around their stars. The stars (with all their planets) also revolve around the center of the Milky Way. (3) Stars (and everything with them) revolver around the center of the Milky Way, NOT specifically because of the black hole, whose mass is way too small for that. Stars move around the center of the Milky Way because they are attracted by all the OTHER masses in the Milky Way (of which the central black hole is only a small part). These other masses include a large amount of some yet-unknown mass, known as "dark matter".
The stars in the Milky Way move in the opposite direction of the sun.
There's only 1 universe the milky way is a galaxy
All of them. The Milky Way is all around us.
Moons do not orbit the Milky Way because they Milky Way is a galaxy. But if you are thinking about the amount of moons in the Milky Way total, it is around 1-2million. Probably even more.
No, the sun is gravitationally bound to the Milky Way galaxy. Its orbit around the galactic center keeps it within the Milky Way.
All of them. The Milky Way is all around us.
No-one found it. The Milky Way was there to be seen before our ancestors were walking around Africa.
