Which constellation is farthest from the earth?

Constellation is an area on the celestial sphere, which is a sphere with any distance and all celestial bodies shine on it.

Please refer to the schematic diagram below. The celestial sphere is based on the observer/earth/sun (compared with the distance between stars, the distance of these images can be ignored; In order to depict the ecliptic, the picture is centered on the sun, which is actually rare. All the constellations are distributed on the surface of the celestial sphere, and the zodiac is no exception:

It can be seen that the zodiac signs (but the 88 constellations) are equidistant from us, and it is meaningless to discuss the distance between constellations. In addition, according to this definition, the constellation is essentially a direction, just like what we call "southeast and northwest" in our daily life. Those who are interested can think about this problem carefully.
