Comment on what would happen if a rogue, earth-size planet ran straight into the sun? anything interesting?

Roche limit applies in a circular orbit, tidal effects are irrelevant in a head on collision.

Famous example of a comet breaking up from entering Jupiter’s roche limit in a highly eccentric orbit (not circular). Spaghettification is also an example of how tidal forces still apply during a head on collision.

Eccentric orbit is still an orbit with tidal forces.
A dead in crash will stretch the sphere, but without angular momentum, it’s just a raindrop.
