Motion of a substantial part of the superfast exoplanets is found to be in the close resonance with the well-known “solar” timescale P 0 ≈ 0.11 days and/or the timescale 2 P 0 / π ≈ 0.07 days (at 99.9% confidence for exoplanet periods P < 2 days). There is also a noticeable lack of the exoplanetary “unstable” orbits with P ≈ 3 π P 0 ≈ 1.05 days, which copies the famous “period gap” of the cataclysmic variables at P ≈ 0.11 days; strangely enough, the ratio of the central periods of these two gaps is equal to π 2 . The exoplanet phenomenon is supposed to be caused by a coherent, with the P 0  timescale, oscillation of gravity, operating within the extra-solar planetary systems.
