minus-square@deegeese@sopuli.xyzlinkfedilink28•5 months agoSorry, but that’s wrong. Roche limit applies in a circular orbit, tidal effects are irrelevant in a head on collision.
minus-square@willow@lemmy.blahaj.zonelinkfedilinkEnglish29•5 months agoFamous 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.
