In the vast celestial canvas, stars often bear multiple names, reflecting historical observations and cultural interpretations. One such star, α Ceti, the brightest star in the constellation Cetus (the Whale), is sometimes referred to as Menkab. While not commonly used today, this name carries a historical significance, offering a glimpse into the past.
Menkab, derived from Arabic, signifies "the nose of the whale." This name aptly reflects the star's position within the constellation, marking the celestial whale's snout. However, Menkab is not the official name assigned by the International Astronomical Union (IAU). Instead, α Ceti is formally known as "Menkar," a slightly altered version of the original Arabic name.
The transition from "Menkab" to "Menkar" highlights the evolution of astronomical nomenclature. While "Menkab" remains a historical artifact, "Menkar" has become the accepted standard in modern astronomy. This shift emphasizes the importance of establishing a unified and consistent naming system for celestial objects, especially as our understanding of the cosmos expands.
While "Menkab" might be a less familiar name, it serves as a reminder of the rich history woven into our understanding of the stars. Each name, whether commonly used or relegated to the annals of history, reflects a moment in time, a cultural perspective, and a dedication to mapping the celestial landscape.

Task: Research another historical star name that has been replaced by a modern, official designation.
Instructions:
Example:
You might find information about the star "Algol" (β Persei), whose historical name meant "the demon star" due to its variable brightness. This name was replaced by "β Persei" following the establishment of a standardized nomenclature system.
Remember: You can use online resources such as Wikipedia, the International Astronomical Union website, or astronomy books for your research.
This is a research exercise, so the answer will vary depending on what you find. The important thing is to follow the instructions and demonstrate your understanding of how star names have changed over time.
