Wouldn't gravity tidal forces rip those planets eventually apart? Like we expect ie Phobos to end up, and Mars has much gentler gravity gradient than this would

Wouldn't gravity tidal forces rip those planets eventually apart? Like we expect ie Phobos to end up, and Mars has much gentler gravity gradient than this would have.
Or would tidal locking somehow prevent it?
- wiml 2y agoI think even for a white dwarf the Roche limit is well inside the inner edge of the habitable range. So a planet that gets torn apart by gravity would already have been uninhabitably close.
