Eccentricities, ∣Z∣, as a function of the innermost period Pin of TOI-4495 (square) and 43 pairs of Kepler near-resonant planets (circles) from S. Hadden & Y. Lithwick (2017). Anticipating different tidal dissipation rates on terrestrial (Rp < 1.7 R) and gaseous (Rp > 1.7 R) planets, we mark them in red and blue, respectively. ∣Z∣ consistent with zero are shown as open circles.
