Algenib (α Per) - Other names for it are Mirfak or Marfak. This yellow-white supergiant with an apparent magnitude of 1.8 is the brightest star in the constellation. With an absolute luminosity 5800 times greater than that of the Sun, it is located 390 light-years away.

Algol (β Per) - It is the most famous eclipsing variable star - it is the main representative of eclipsing variable stars with a subgroup of Algol type. Sometimes it is referred to as the "winking demon", which is related to its representation as the eye of Medusa. It was also depicted this way in ancient Greece, but there are no records proving that anyone noticed its light changes at that time. It was first observed by Italian astronomer Geminiani Montanari from Bologna in 1667, making it the only known variable star in the Middle Ages. Its true nature was correctly recognized by English astronomer John Goodrick in 1782.

ζ Per - A binary star in an interesting setting. The companion, with a magnitude of 9.5, is located at a distance of 12.9" from the main pale blue component with a brightness of 2.9 magnitude, and there are two other stars nearby in the same field of view. The first star, with a magnitude of 11, is located at a separation of 33", while the second star, with a magnitude of 9.5, is at a distance of 94". It is located 750 light-years away. The closest star shares a common proper motion with the main component.

ε Per - The binary star, with a brightness companion of 8.1 magnitude, is located at a distance of 8.8" from the primary component (2.9 magnitude). The primary component is 2,500 times brighter than our Sun. It can be resolved with a telescope with a 6cm objective diameter. It is located 640 light-years away.

Miram (η Per) - Astronomical text translation:

A very easily distinguishable pair with magnitudes of 3.8 and 8.5 at a separation of 28.3". It resembles the well-known double star Albireo, as its components have a golden-blue contrast. 66" almost west of the main component, there is a close double star composed of components with magnitudes of 10mag and 10.5mag, which is likely part of the η Per system. A dozen fainter stars form a small star cluster around this system.
