In theoretical computer science, more precisely in the theory of formal languages, the star height is a measure for the structural complexity of regular expressions and regular languages. The star height of a regular expression equals the maximum nesting depth of stars appearing in that expression. The star height of a regular language is the least star height of any regular expression for that language.The concept of star height was first defined and studied by Eggan (1963). (Wikipedia).
Teach Astronomy - Stellar Size
http://www.teachastronomy.com/ The size of a star is a fundamental quantity, but it's very hard to measure because stars are so far away. The Sun, our nearest star, is half a degree across on the plane of the sky, but if we move the Sun to a distance of one parsec its size would be about
