Pisces is a constellation, not a physical object with a surface temperature. It's a grouping of stars that appear close together in the night sky from our perspective on Earth.

Each star within the constellation Pisces has its own unique surface temperature, which can vary greatly depending on the star's size, age, and composition.

To find the surface temperature of a specific star in Pisces, you would need to specify the star's name. For example, the star Fomalhaut, which is located near the constellation Pisces, has a surface temperature of approximately 8,500 Kelvin.
