Recently, we have shown that the orbital radii of planets and major satellites could be described by the parabolic law r_n = const.×n², where values of n are consecutive integers. The constant depends on a particular system and includes a dimensionless factor f, which is now correlated with some relevant parameters. Using the parabolic law, we discuss a possible existence of the terrestrial- and/or Jovian-type planets in extra-solar single-star systems, assuming variable stellar mass. An extension to the pulsar PSR B1257+12, the only one with three detected planets, is considered.
