Which star is recognized as the brightest in the constellation Perseus?

The brightest star in the constellation Perseus is Alpha Persei, also known as Mirfak. This star is notable for its apparent magnitude, which is approximately 1.79, making it stand out prominently in the night sky. Alpha Persei is a yellow supergiant, and it serves as a significant point of reference for identifying other stars and celestial objects within Perseus.

In the context of this question, Algol, while an important star in Perseus known for its eclipsing binary nature, is not the brightest; it has a lower apparent magnitude (around 2.12) compared to Alpha Persei. Epsilon Sagittarii does not belong to Perseus, as it is actually located in the constellation Sagittarius. Antares, although a bright star in its own right, is part of the constellation Scorpius, not Perseus. Thus, Alpha Persei stands out as the clearest choice in this question due to its brightness and significant role within the constellation itself.
