  The paper explores connection between the order and the type of an entire
function and the speed of the best polynomial approximation in the unit disk.
The relations which define the order and the type of an entire function through
the sequence of its best approximations, have been found. The results were
obtained by generalization previous results of Reddy, I.I. Ibragimov and N. I.
