Tidal heating in planets extracts energy from orbital motion
Tidal heating in planetary bodies taps into orbital energy, converting it to heat while driving orbital evolution such as circularization and migration.
The retrieved papers consistently describe tidal heating as a process driven by tidal friction that extracts energy from orbital motion, leading to phenomena like orbital decay, circularization, and migration. Therefore, the claim is supported by multiple relevant astrophysical studies.

This study explains how orbital energy is dissipated as tidal heat in planetary interiors, driving inward migration and circularization.

This paper models tidal dynamics and shows how tidal dissipation and heating are linked to the evolution of planetary orbits.

This work discusses how Earth-Moon tidal interactions couple over geological time, explicitly linking tidal energy dissipation to changes in the lunar orbit.
