In his early astronomical career, he studied variable stars and in particular close eclipsing binary stars. He attended Cambridge University in 1938 and later that year he went to Harvard College Observatory. After the war he became head of the astronomy department at the University of Manchester. He later assisted NASA with the Apollo program as an external expert. He was editor-in-chief of the journal ''Astrophysics and Space Science'' since its foundation in 1968 until his death in 1993. The asteroid 2628 Kopal was named in his honor. Monographs * Zdeněk Kopal: ''An introduction to the study of eclipsing variables.''

2628 Kopal
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler".
