What process starts Galaxies and stars to rotate?
A new star in a large cloud of gas would pull gas in from all directions so what decides its rotation?
And how does all the rotation in the Universe start?
Water down a plug hole I understand but in a early Universe with the first stars I don't.
The North Star!
All the constellations appear to rotate round the pole star because the pole star is in line with the axis that the Earth rotates around with us on board.
Cassiopeia and the Big Dipper appear to rotate counterclockwise around the North Star in the northern hemisphere.
All 8 planets in our solar system rotate around a star, our sun. Virtually all planets rotate around a star.
All stars rotate (spin). Some spin faster than others, but all stars will rotate as without this rotation, the star will literally fall into space.
Neutron stars rotate rapidly due to their conservation of angular momentum. When a massive star collapses into a neutron star, its core spins faster as it contracts. Since angular momentum is conserved, the neutron star continues to rotate rapidly as a remnant of the collapsed star.
No, a planet does not necessarily have to rotate around a star. There are rogue planets that do not orbit any star and instead wander through space independently. These planets are not bound to a specific star and travel alone through the galaxy.
easy you go up to it and push on it
The North Star, or Polaris. This star remains nearly stationary in the sky while all other stars seem to rotate around it due to the Earth's rotation on its axis.
Not just the big dipper but all of the stars appear to rotate around the North Star because Earth is rotating. The North Star does not appear to move because it is in line with Earth's axis of rotation.
I don't know whether such a star exists, but that might be the case for a star with an extremely large diameter.
None. The sun is a star, and no moons rotate around stars.
