Hamers: «Gravity can cause
strong tidal effects, just as the moon's gravity causes high and low tide on earth.
A sizeable moon in retrograde orbit will, once captured, have
a strong tidal effect on the primary (Neptune in this case) in such a way as to make the moon's orbit become both smaller and more nearly perpendicular to the primary's equator.
Not exact matches
Since a thinner ice shell retains less heat, the
tidal effects caused by Saturn on the large fractures in the ice at the south pole are no longer enough to explain the
strong heat flow affecting this region.
It is rather early to speculate, but maybe Pluto captured Charon only a few hundred million years ago (rather than billions), and we are seeing the
effect of the very
strong tidal interactions that would have ensued.
Since the
tidal effect is
strongest when the moon is closest to the primary, it also tends to make the orbit more circular.
The dwarf elliptical galaxy SagDEG in the direction of the Milky Way's center is stretched and distorted from the
tidal effects of the Milky Way's
strong gravity.
Such proximity introduces hazards that are of negligible importance for life on Earth: increased exposure to (time - varying) short wavelength radiation,
stronger magnetic fields,
tidal effects, and atmospheric removal by the stellar wind.
The preoccupation with focusing only on the visible surface of the earth, and disconnecting the
strongest tidal and gravitational forces in the Earth / Moon system has lead to this misunderstanding of why the lunar
tidal effects (when not considered) that produce the teleconnections seen in so many global circulation patterns leaves so many easy to answer questions.
