It covers an area of 13,100,000 square kilometres (5,100,000 sq mi), or 8.8% of Earth’s total land area; and is the largest subregion of Asia by area, occupying approx. 29.4% of Asia’s land area, but is also the least populated, with a population of around 37 million, accounting for merely 0.74% of Asia’s population.

DELTA PER (Delta Persei). Dominated as it is by its two brightest stars, Mirfak and Algol (Alpha and Beta Persei), the next four stars of glorious Perseus, the mythical rescuer of Andromeda, are often ignored. This quartet, which consists of Gamma, Delta, Epsilon, and Zeta, are all nearly the same mid-third magnitude brightness, and add great sparkle to the northern constellation.
