I do not mean in relatively of distance from earth. I mean how they are seen in the night sky.
None, the constellations are just collections of stars as seen in our night sky. Even the stars in a given constellation are 100's or 1000's or 10000's or 1000000's of light years apart from one another.
If you're asking where in the night sky, the answer is always changing since the planets move through the sky differently than the stars.
None really as the constellationas are actually made up of stars that are millions and trillions of light years from each other and the Solar System.
Depends on the time of year and which planet and where it is compared to Earth. The planets move in relation to the stars, so their positions change throughout the year.
If you mean right now, Saturn is in Leo and Mars is in Cancer.
In June, Jupiter will be near Sagittarius, Mars will be closer to Saturn in Leo, Uranus will be in Aquarius, and Neptune in Capricorn.
