Pisces is right next to Aries and Aquarius, and right across from Virgo.
The Pisces constellation is actually bordered by several other constellations: Triangulum Andromeda Pegasus Aquarius Cetus Aries
Since the beginning of Time itself, just like every other constellation ! What's your question's purpose, anyway?
There is no zodiacal constellation north of other zodiacal constellations. A zodiacal constellation is a constellation that is along the ecliptic. There are zodiacal constellations to the left and right of Aquarius (Pisces & Capricornus, respectively), but just other, regular constellations above and below Aquarius.
Pisces is a constellation, not a single star. The constellation contains a very large number of stars and other cosmic objects which have no astrophysical relationship with one another. It is simply that they are located in such direction from earth, and are so far away, that they appear to move together. The distances to the cosmic objects that make up Pisces covers a huge range, as do the distances to other major stars. There is, therefore, no meaningful way to answer your question.
Hard to compare... One is a planet, the other a constellation.
Any constellation is a group of stars that appear to form some kind of pattern, but have no connection with each other. They all happen to be in roughly the same direction from us, but they're all at different distances. So there's no such thing as a constellation's distance from us.
In the November sky, the constellation Pisces has a right ascension (RA) of approximately 1 hour and a declination (Dec) of around +10 degrees. This places Pisces in the region of the celestial sphere where it can be observed during the evening hours. While not as prominent as other constellations, it can still be seen with the naked eye under dark skies.
The constellation Pisces is primarily made up of several notable stars, including Alpha Piscium (also known as Van Maanen's Star), which is the brightest star in the constellation. Other significant stars include Beta Piscium (also known as Fumalsamakah) and Gamma Piscium. The constellation is often depicted as two fish connected by a ribbon, symbolizing the mythological story of the fish that helped save Aphrodite and Eros. Overall, Pisces consists of dimmer stars, making it less prominent than some other constellations.
The matches for a Pisces are any other water sign (Cancer, Scorpio, or another Pisces); or the opposite sign for a Pisces, Virgo
Pegasus is a constellation located in the northern sky. It can be found near other notable constellations such as Andromeda and Pisces. Its shape is often likened to a large square or a Great Square of Pegasus.
The Fishes...
Generally speaking Pisces - Aquarius relationships are harmonious.
