Do other planets have precession?

Question

is the motion of precession just something that spinning bodies nearly inevitably do? what about the sun?

Answer 1

As far as I know, yes, other planets do have precession.  The gravitational pull that each planet projects, depending on size, density, and relative closeness to other planets, or stars (our sun for instance) causes rotation.  I've never heard of any other planet or comparable land mass that does not precess.  I also believe that without precession, planets like Earth wouldn't be able to sustain life due to inadequate sunlight, so...if there are another other Earth-like planets, I'm sure that motion has to be a factor

Answer 2

Yes, any  *solid* spinning body will precess.  You would need perfect symmetry of the body and orbit to not have some precession.

Answer 3

Yes, all rotating bodies experience procession to some degree.  Procession is largely relevant to the mass of other bodies gravitational pull (for instance, the Earth's procession is called lunisolar precession, and is caused by the torque force of the moon and sun as applied to the Earth).  So, indeed, a star (such as the sun) experiences precession, though unless there is large amounts of mass, it might not be noticeable.

Answer 4

Yes, it is inevitable as any small disturbance causes precession of rotating bodies. But it can be too small to be measured from Earth.

Answer 5

Yes. As a object gathers mass, from gasses or bodies collide, their rotation cause them to become round. Unlike the teaching's of the ancient Greeks objects in space are not perfectly round. They are wider at the equator.

The gravitational pull, from other Stars, and Planets, will causes any object to precess, including the Sun.
