What reading level is Planetary And Stellar Studies book?
To quickly assess the difficulty of the text, read a short excerpt:
Star. ) = 6312 X (light of 13^-mag. Star. ) so that a cluster of only 6, 312 stars of the magnitude would give the light of a 4th-mag. Star. Sir John Herschel, however, considered that if the light of Omega Centauri were compressed into a point, and not diffused as it is over a considerable area, the cluster would probably shine as a star of about the 3rd magnitude. This would give Number of stars = (2'5i2) IOtS = 15856 a sufficiently large number of stars to be contained in a portion of the sk...y considerably less in area than that covered by the full moon.
Were it possible to approach this cluster to say y^th of its present distance, it would then expand into a circle of about 33 in diameter, and in this circular portion of the sky would be crowded say 15, 000 stars of between the 3rd and 4th magnitude a truly magnificent spectacle.
