galactic tide in a sentence

• Comets usually have highly passing stars and the galactic tide.
• Tidal tails occur as a result of galactic tide forces between interacting galaxies.
• It came from the Oort cloud with a loosely bound chaotic orbit that was easily perturbed by galactic tides and ejection trajectory.
• Comets are thought to orbit the Sun at great distances, but then be perturbed by passing stars and the galactic tides.
• Just as the Moon raises two water tides on opposite sides of the Earth, so a galactic tide produces two arms in its galactic companion.
• This shows that the effects of the galactic tide are quite complex, and depend heavily on the behaviour of individual objects within a planetary system.
• When the Sun's orbit takes it outside the galactic plane which bisects the galactic disc, the influence of the galactic tide is weaker.
• Particular areas of interest concerning galactic tides include satellite galaxies, and the Milky Way's tidal effect on the Oort cloud of the Solar System.
• A "'galactic tide "'is tidal force experienced by objects subject to the gravitational field of a galaxy such as the Milky Way.
• It has been suggested that the galactic tide may also contribute to the formation of an Oort cloud, by increasing the perihelia of planetesimals with large aphelia.
• It's difficult to see galactic tide in a sentence .
• Cumulatively the effect can be quite significant, however; up to 90 % of all comets originating from an Oort cloud may be the result of the galactic tide.
• Matese's case for the influence of galactic tides, co-authored with colleagues Daniel Whitmire and Patrick Whitman, will appear later this month in the Astrophysical Journal.
• Moreover, the influence of the surrounding stars and that of the galactic tide should have sent the Oort cloud comets either closer to the Sun or outside of the Solar System.
• It came from the Oort cloud with a loosely bound chaotic orbit that was easily perturbed by galactic tides and epoch 1950 ), C / 2013 V5 had an orbital period of several million years.
• Objects scattered outward by Uranus and Neptune onto larger orbits ( roughly 5, 000 AU ) can have their perihelion raised by the galactic tide detaching them from the influence of the planets forming the inner Oort cloud with moderate inclinations.
• But with Matese's new calculations on galactic tides, he said, he is now convinced this is the explanation for how comets are driven inward toward the sun from the Oort cloud, a huge halo of comets that surrounds the solar system.
• Because of this gradient, galactic tides may then deform an otherwise spherical Oort cloud, stretching the cloud in the direction of the galactic centre and compressing it along the other two axes, just as the Earth distends in response to the gravity of the Moon.
• They are thought to be remnants of the primordial soup from which the solar system formed, tiny objects still lurking by the trillions in vast clouds or belts beyond the outermost planets, where they remain in suspension until some galactic tide or passing star sends a few hurtling toward the inner solar system.
• By mid-2009 the project's main astrophysical interest is in the Sagittarius Stream, a stellar stream emanating from the Sagittarius Dwarf Elliptical Galaxy which partially penetrates the space occupied by the Milky Way and is believed to be in an unstable orbit around it, probably after a close encounter or collision with the Milky Way which subjected it to strong galactic tide forces.
