(Particles trying to merge
on the side of a growing planet closest to the star would feel a much greater gravitational pull from the star than merging particles
on the far side of the planet; those
tidal forces would pull a growing planet apart.
When planetary scientists started studying the photographs and data from Voyager and the subsequent Galileo mission that studied the Jovian system during the 1990s and early 2000s, they confirmed this notion: these ridges, or lineae, are fructures, or cracks,
on Europa's icy surface, caused be the intense
tidal forces of the massive, nearby Jupiter and the orbital resonances with the other nearby moons.
A new study by Kaloyan Penev et al suggests that Q varies a lot depending
on the
tidal «
forcing period» (that is, the period at which a planet would appear to orbit, if viewed when rotating with the spinning star, with an extra factor of a half since there are two tides per orbital cycle).
Tidal forces acting
on Io are so pronounced that the satellite's interior is literaly molten, causing the moon to be the most volcanically active planetary body in the Solar System, sporting over 400 active volcanoes!
The liquid ocean scientists are so interested in is likely a result of
tidal forces working
on the moon as it whips around Jupiter.
The vast network of crisscrossing cracks that are seen
on the surface of Europa are caused by the intense
tidal forces of the massive, nearby Jupiter and the orbital resonances with the other nearby moons of the Jovian system, similar to the way that the gravity of the Earth's Moon causes tides
on the oceans of our home planet.
However, in rare instances, two of these objects orbit each other so closely ---- orbiting every few minutes ---- so that the helium from the lighter of the two gets pulled off by
tidal forces and accumulates
on the more massive white dwarf.
In addition,
tidal forces affecting the Oort Cloud come from the differential gravitational
forces exerted by stars in the Milky Way's galactic disk and by the galactic core
on the Sun and comets as a result of their relative location in the Solar System, which have been modelled with numerical simulations (Duncan et al, 1987).
The Galileo mission that studied the Jovian system during the 1990s and early 2000s confirmed the scientists» speculations that these ridges were fractures, or cracks,
on Europa's icy surface, caused be the intense
tidal forces of the massive, nearby Jupiter and the orbital resonances with the other nearby moons of the Jovian system.
Tidal forces have a greater impact
on comets than the perturbations of passing stars, and so comets located beyond 200,000 AUs are easily lost to interstellar space.
