A polar orbit is an orbit in which a satellite passes above or nearly above both poles of the body (usually a planet such as the Earth, but possibly another body such as the Sun) being orbited on each revolution. It therefore has an inclination of (or very close to) 90 degrees to the equator. Except in the special case of a polar geosynchronous orbit, a satellite in a polar orbit will pass over the equator at a different longitude on each of its orbits.
A most-perfect magic square of order n is a magic square containing the numbers 1 to n² with two additional properties: Each 2×2 subsquare sums to 2s, where s = n² + 1. All pairs of integers distant n/2 along a (major) diagonal sum to s.
