Sažetak
The square law rn = r1n2 for orbital sizes rn (r1 is a constant dependent on the particular system, and n are consecutive integer numbers) is applied to the recently discovered planets of u Andromedae and to pulsars PSR B1257+12 and PSR 1828-11. A comparison with the solar planetary system is made. The product nvn of the orbital velocity vn with the corresponding orbital number n for planets of u Andromedae is in good agreement with those for terrestrial planets, demonstrating the generality of the square law in dynamics of diverse planetary systems. "Quantized velocity" of nvn is very close to 24 kms-1, i.e. to the step found in the quantized redshifts of galaxies. A definite conclusion for planetary systems of pulsars requires additional observations.
