Tell Your Friends.....

In the northern sky, amidst the mythological constellation of Perseus, lies Mirphak, a celestial beacon whose brilliance outshines all others in its stellar family. Known formally as Alpha Persei and traditionally as Mirphak or Algenib, this star has been a point of fascination and study for astronomers and stargazers alike1.

A Supergiant’s Tale

Mirphak, a yellow-white F-class supergiant, is the prime member of the Alpha Persei Cluster, also known as Melotte 202. With an apparent magnitude of 1.8, it is easily visible to the naked eye and has been a navigational star for centuries. The star’s mass, approximately 8.5 times that of our Sun, and its radius, a staggering 68 times larger, mark it as one of the true giants of our galaxy1.

The Dance of Gravity

This supergiant sits at the heart of the Alpha Persei Moving Cluster, a group of stars bound by gravity, dancing through the cosmos in a synchronized ballet of stellar motion2. The cluster, a rich field of study, is easily observed with binoculars or a small telescope, offering a glimpse into the dynamics of star families.

A Star’s Destiny

The fate of a star like Mirphak is a subject of intrigue. Astronomers ponder whether it will end its life in a spectacular supernova or fade away as a white dwarf. Mirphak’s mass hovers around the critical threshold that determines the outcome of its final performance2.

Cultural Luminary

Beyond its astronomical significance, Mirphak holds a place in cultural history. Its traditional name, derived from Arabic, means ‘elbow’, a nod to its position in the sky. In Hawaiian astronomy, it is known as Hinaliʻi, a name commemorating a great tsunami and marking the beginning of the migration of Maui1.


Mirphak continues to shine as a subject of scientific inquiry and cultural lore. As we gaze upon this stellar giant, we are reminded of the vastness of the universe and the timeless tales written in the stars.

I hope you enjoyed this journey through the cosmos, exploring the wonders of Mirphak. If you’re interested in stargazing, Mirphak’s consistent brightness makes it an excellent starting point for a night under the stars. Happy observing!
