Sentences with phrase «planetary orbits»
"Planetary orbits" refers to the circular or elliptical paths that planets take when they move around the Sun. It shows how planets travel in a loop around the Sun due to gravity, just like how the Moon goes around the Earth. Full definition
Each section of the novel is named for a stage of planetary orbit.

reduces the likelihood of stable planetary orbits at increasing distances from each star or binary pair Alan Hale, 1994.
Finally, noncoplanarity between the component stars of a binary system should not have a significant impact on the stability of close - in planetary orbits around each star (Alan Hale, 1994).
«The study demonstrates how making measurements of planetary orbit changes throughout the solar system opens the possibility of future discoveries about the nature of the Sun and planets, and indeed, about the basic workings of the universe,» said co-author Maria Zuber, vice president for research at MIT.
And, I said earlier that planetary orbits get unstable in multiple star systems, but in recent observations, it has been found that some multiple star systems also have planets.
reduces the likelihood of stable planetary orbits at increasing distances from each star or binary pair (Alan Hale, 1994).

In between, general relativity has made its mark on the Global Positioning System, while explaining anomalous planetary orbits and the whirling death dances of the remnants of giant stars.
Recent numerical integrations, however, suggest that stable planetary orbits exist: within three AUs (four AUs for retrograde orbits) of either Alpha Centauri A or B in the plane of the binary's orbit; only as far as 0.23 AU for 90 - degree inclined orbits; and beyond 70 AUs for planets circling both stars (Weigert and Holman, 1997).
That would be like a planet in our solar system orbiting perpendicular to the plane in which all the other planetary orbits (generally) exist.
This animation shows a chaotic solar system and changing planetary orbits playing out over billions of years, illustrating the slight chance in the distant future of planetary collisions.
Assuming that the spectroscopic companion B does not preclude a stable inner planetary orbit, the distance from Star A where an Earth - type planet would be «comfortable» with liquid water is centered around only 0.457 AU — between the orbital distances of Mercury and Venus in the Solar System.
Vogt believes a 5 - planet model with all circular orbits trumps a 4 - planet model with eccentric planetary orbits, but adds that it may take time and further data to give a definitive answer.
In Kepler's final planetary model, he described planetary orbits as following elliptical paths with the Sun at a focal point of the ellipse.
On March 15, 2004, a team of astronomers (including Mike Brown, Chad Trujillo, and David Rabinowitz) announced the discovery of a very large planetary body named Sedna in one of the most distant planetary orbits yet discovered within the Solar System.
I think that it has been shown that planetary orbits qualify for the Newtonian treatment and that the orbit of Earth is indeed deterministic and chaotic to a sufficient degree of accuracy and precision.
Similar arguments dispose of the exactly circular view of planetary orbits.
The supposed perfect circles, that is simplest conic sections, of planetary orbits, taken together, form a very complicated whole, painfully lacking in the apparent simplicity of any single circle.
They create no changes in gravitational pull, solar radiation, planetary orbits, or anything else that would impact life on Earth.
And what can this mean except that, like those planetary orbits which seem to traverse our solar system without remaining within it, the curve of consciousness, pursuing its course of growing complexity, will break through the material framework of Time and Space to escape somewhere towards an ultra-center of unification and wholeness, where there will finally be assembled, and in detail, everything that is irreplaceable and incommunicable in the world.
He insisted that planetary orbits were circular (modified by secondary circles, the epicycles).
