Do all the planets follow roughly the path of the old 12 zodiac constellations in the sky?

why so for this??



and do the constellations follow the path of the sun in the sky or near it ?



please describe and explain.



Thanks for your answres!Do all the planets follow roughly the path of the old 12 zodiac constellations in the sky?
all previous answers have missed out that neptune has an eccentric orbit, the other 7 planets and pluto all orbit anti-clockwise in the same plane and pass throught every constellation, but neptune was hit hard by a large object a few billion years ago and goes clockwise in a alightly different plane so does not pass through all the constellations in every neptunian year
All the planets orbit the sun within the same plane (give or take a few degrees), including the Earth.

The Earth's axis is tilted to that plane by 23.5 degrees, so it cuts across our sky at an angle (called the "ecliptic").



So from our point of view, all the planets appear in our sky pretty close to that ecliptic line.



The constellations are not in orbit around the sun.

They are the patterns that people see in the random arrangement of distant stars.

The 12 zodiac constellations are just the ones that humans saw along that ecliptic line in our sky.

The 88 official constellations are all over the entire sky - they rise and set like any astronomical object does due to the Earth's rotation. And they change their location in our sky due to the Earth's orbit around the sun.



But the constellations have absolutely no relationship to our solar system or our perspective on the planetary orbits.Do all the planets follow roughly the path of the old 12 zodiac constellations in the sky?
All the planetary orbits (of the 8 recognised planets) lie in the same plane, or very close to each other. Because of this, they will always appear to be following similar paths in the sky.



From the Earth point of view, this means that the planets and the Sun follow similar paths in the sky. The planets are never far from the ecliptic.
Yes



This is because the planets formed with an orbiting disk around the sun. Different parts of the disk coalesced into planets. This is why all the planets are on the same plane.Do all the planets follow roughly the path of the old 12 zodiac constellations in the sky?
Some times,planets get into a 13th Constellation known as Ophucus

Due to p recession of equinox
