What name do astronamers give to the wobbling of the earth on its axis?

"Wobble" isn't a very precise term.
The Earth has a small, short period "wobble" simply due to the fact that it isn't perfectly symmetrical and balanced.
This also causes a small, longer period "wobble" due to the effect of the Moon's gravity on the (slightly asymmetric) Earth.
And there are wobbles due to other (and to me unknown) causes.
But I suspect what you're talking about is what's technically called precession, which has a special name because it's a very particular type of "wobble". The Earth precesses on its axis in a cycle lasting about 29,000 years. Because of this, Summer 15,000 years ago ... or 15,000 years from now... would have occurred in the northern hemisphere in December rather than June.

∙ 14y agoThe gradual change of the direction of Earth's axis - often compared to the wobble of a spinning top - is called precession. It is caused by gravitation from the Moon and Sun, combined with the fact that Earth is not a perfect sphere. The weird part is that, due to the spinning of the Earth, if any force is exerted to straighten up the Earth's axis, it changes direction, instead, at a right angle to that force. Same as in a spinning top.

The earths rotation is direct cause of?
seasonsRotation around the sun gives the seasons because the earth is tilted. Rotation about earth's axis give day and night.
How long does it take Eris to rotate on its axis?
25.9±0.5 hr, according to the Wikipedia article.
What stars does not move in the night sky because it is directly over the Earth's axis of rotation?
Which following stars . . you didn't give any names :) But the Pole star is almost in line with the Earth's north and south poles, less than 1 degree off.
Does earth spins on it's axis from east to west causing night and day?
Yes. Because Earth spins around the sun and rotates on its axis, different parts of the world face the sun at a different time, causing day and night. +++++++ Answer ++++++++++ Your question is about the earth's orbit causing night and day. The answer for that is NO. It's the earth's rotation that causes night and day. The earth's axis of rotation compare to the orbit is what causes the seasons.
Does the earth spin around the sun or moon?
The Earth neither spins round the Sun nor the Moon. The Earth rotates(spins) on it own axis, top give us night and day. The Moon revolves (orbits) round the Earth once a month (Moonth). The Earth and Moon, as a binary system revolve (orbit) round the Sun once a year. The Moon making 13 orbits of the Earth in once a year.
What does earth spinning on its axis give us?
Day and night.
The earths rotation is direct cause of?
seasonsRotation around the sun gives the seasons because the earth is tilted. Rotation about earth's axis give day and night.
How does earth shape give as different seasons?
The earth's shape (almost spherical) has absolutely no influence on the seasons, which are associated with the inclination of its axis relative to its orbital plane.
What does earth make when it spins on it's axis every 24 hours?
One revolution, give or take a tiny bit.
What is the direction of mars from earth?
You can't give a definative direction as such as the Earth spins on its axis and also orbits the Sun, as does Mars, so their relative positions to each other alter. Mars is further away from the Sun than Earth.
Which side of earth is in day light?
Whatever answer I give you will be wrong in 12 hours. The Earth spins on its axis every 24 hours, so each side of the planet gets about 12 hours of day light per day. (Less in winter, and more in summer, due to the 23 degreetilt of the axis.)
What is the diagnoses AXIS?
What does Axis I, Axis II, Axis III, Axis IV and Axis V when used with a mental diagnoses? Could you please give more information. Was AXIS diagnosed in an adolescent or due to alcohol or drug abuse? Thank you
Does sun give off more heat in the summer?
No, the sun does not give off more heat in the summer. It only seems hotter because the axis of the Earth, that you are on, is now pointed closer to the sun, where as in winter you are actually farther from the sun, since the axis is pointed in the other direction, and therefore you do not experience the same warmth as in summer.
How long does it take Eris to rotate on its axis?
25.9±0.5 hr, according to the Wikipedia article.
Does the x axis give latitude coordinates?
you are correct!
What terms did the allies offer the axis by declaring that they would accept unconditional?
axis countries must give up completely
What stars does not move in the night sky because it is directly over the Earth's axis of rotation?
Which following stars . . you didn't give any names :) But the Pole star is almost in line with the Earth's north and south poles, less than 1 degree off.
