Sentences with phrase «planetary orbits around»

Successive breakthroughs in the natural sciences gave rise to a system of graphical schema to represent the natural order — whether the planetary orbits around the sun, the life cycle of plants, or the double - helix structure of DNA.

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 history of science provides many examples of this combination of analogy and innovation in the creation of models which were useful in generating theories.4 The «Bohr model» of the atom, in which «planetary» electrons revolve in orbits around a central nucleus, resembles the solar system in certain of its dynamical properties; but the key assumption of quantum jumps between orbits had no classical parallel at all.

A solitary planet in an eccentric orbit around an ancient star may help astronomers understand exactly how such planetary systems are formed.

The International Astronomical Union defines «planet» as a celestial body that, within the Solar System that is in orbit around the Sun; has sufficient mass for its self - gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape; and has cleared the neighbourhood around its orbit; or within another system, it is in orbit around a star or stellar remnants; has a mass below the limiting mass for thermonuclear fusion of deuterium; and is above the minimum mass / size requirement for planetary status in the Solar System.

Nearly every one of these exoplanets has been discovered in orbit around a mature star with a fully evolved planetary system.

The Cassini spacecraft swinging through orbits around Saturn and its satellites has been sending back extraordinary pictures of its own, particularly from the moon Enceladus, and if they are less famous among most of the public, they may be no less inspirational to planetary scientists.

A previous ISAS planetary probe, Nozomi, failed to enter an orbit around Mars in December 2003 after suffering multiple failures and was eventually abandoned.

In one case, an Earth - sized planet could orbit in the habitable zone (capable of having liquid water on their planetary surface) around two stars close together.

However, the inner, eccentric orbit of a giant planetary companion «b» recently discovered around 54 Piscium would probably disturb the orbit of such an Earth - type planet.

The scientists report that a minor planet in the planetary system was orbiting around the white dwarf, and its trajectory was somehow altered, perhaps by the gravitational pull of a planet in the same system.

A solitary planet in an eccentric orbit around an ancient star may help astronomers understand exactly how such planetary systems are formed.

Test simulations of the orbits of the three planets around 61 Virginis suggest that the planetary system's orbital configuration is dynamically stable because of low orbital eccentricities for at least 365 million years.

And as you may know the Planetary Society did an analysis that shows we could be in orbit around Mars, which would be analogous to the Apollo 8 orbit of the moon in 2033 without changing anything about the NASA budget just adjusting it for inflation.

-- If the central star of a planetary system burns out, there will be no further evolution of life on the planets that have orbits around it.

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.

On the other hand, the discovery of a brown dwarf companion in a wide orbit that could perturb dormant comets in an Oort Cloud around Epsilon Indi inwards towards the star's inner planetary regions may periodically shower an Earth - type, inner planet with catastrophic impacts.

However, if the existence of a relatively close, second companion (see Star Bc below) around Bab — with an orbital period of 2.2 to 2.9 years or less — is confirmed, then a planetary orbit in Star Ba's water zone may not be stable over the long run.

Adding to the recent spate of planetary finds, astronomers from NASA's Goddard Space Flight Center and San Diego State University (SDSU) announced yesterday they've discovery the largest - known planet to orbit two stars, confirming theories about large planets around binary systems.

However, the giant planetary companion «A1» or «b» recently discovered around Star A could disturb the stability or the development of such a rocky planet in this orbit.

Despite possible orbital eccentricity, planetary candidate «g» average orbit distance of around 0.6 AU should keep it wholly within HD 40307's habitable - zone between 0.4 and 1.0 AU, even if the object is relatively cloudless.

On July 21, 2003, some astronomers provided evidence from recent discoveries of giant extrasolar planets in mostly inner orbits around host stars that planetary systems may be more common around stars whose spectra show an enriched abundance of elements heavier than hydrogen and helium — also called high «metallicity» (exoplanets.org press release; and Gonzalez, 1999).

Variations in how the Earth is tilted and its orbit around the sun make for a pattern of planetary warming phases followed by cooling phases across the millennia.

That would make the sudden end of the last ice age a product of assuming our own independent orbit around the sun, and the various spikes due to planetary interactions as the planets equalized charges and stabilized their orbits to what we see today.
