It causes the set of constellations visible on any particular night each year to change over many years.
It slowly changes which star is nearest to the north pole of the sky.
So, Polaris will not always be the "pole star".
The Moon's gravitation
Precession, which in this case refers to a movement of Earth's axis. A full "turn" takes about 26,000 years.
In the last couple of million years, the Earth has experienced dozens of ice ages. The last one ended about 15,000 years ago. We don't know if they are related at all to the Earth's "precession", which is a 26,000-year-long "wobble" in the Earth's spin. There is no reason for precession to have any effect on Earth's climate, since the 'tilt' of the axis remains constant throughout the cycle of precession.
It depends on what object you are talking about. If you are asking about the precession of the Earth's axis, then that is about 26,000 years.
seasons are caused by the tilt of the earth. since the earth is in a slight eliptical orbit around the sun, when we are closer to the sun in January is where the northern hemisphere will still have winter and further from the sun in July when summer occurs. this is expected to flip in 26,000 years because of earths 3rd axis known as axial precession
Yes - more or less. It changes its direction in space ("precession") very slowly, making a full cycle every 26,000 years or so.Yes - more or less.

precession
Procession of the Equinox
The Earth is a spinning top (gyro) with a different moment of inertia about the spin axis than the other two axis. Therefore, it acts like a spinning top with both precession and nutation. Precession of the polar axis (relative to a 'fixed' distant star) forms a cone. The precession period (~26,000years) is the time it takes for the cone to be traced. Nutation occurs normal to the precession cone and has a much faster period (~18.6yrs).
I think you are referring to a phenomenon called Nutation.
it creates the seasons.
Earths rotation around its axis
Due to the earths precession (How the earth 'wobbles' on its axis) the pole star changes over time. Though this takes many, many years
the Earths rotation
There would be no four seasons if the earths axis was not tilted.
A Precession is the changing direction of earth's axis
Earth's axis wobbles.
Yes they are.
