	Eccentricity - Wikipedia, the free encyclopedia

	Eccentricity (orbit) - Wikipedia, the free encyclopedia
		The eccentricity of this conic section, the orbit's eccentricity, is an important parameter of the orbit that defines its absolute shape.
		Eccentricity may be interpreted as a measure of how much this shape deviates from a circle.
		Through time, the eccentricity of the Earth's orbit slowly changes from nearly 0 to almost 0.05 as a result of gravitational attractions between the planets (see graph [1]).

		American millionaire Howard Hughes, for example, was considered to be very eccentric in his old age, when he stored his urine in glass jars and never cut his hair or nails.
		Eccentricity is often associated with genius or extreme creativity.
		In this view, the eccentric's habits are incomprehensible not because they are illogical or the result of madness, but because they stem from a mind so original that it cannot be conformed to "normal" society.

	Eccentricity TSI
		Eccentricity is measured while the turbine is on slow roll (1 to 240 RPM below the speed at which the rotor becomes dynamic and rises in the bearing on the oil wedge) and requires special circuitry to detect the peak- to-peak motion of the shaft.
		As the eccentricity measurement is not required after a turbine is brought to speed and under load provisions are made to lock the measurement to zero.
		As most eccentricity sensors are internally mounted and are not visible from the outside of the machine whatever the angle of orientation is finally chosen it is very important that the mounting location be documented for future reference.

		In the Milankovitch theory, the peak near 0.01 (100 kyr period) is attributed to eccentricity, the peak near 0.024 (41 kyr period) to obliquity, and the peak near 0.043 (23 kyr period) to precession.

		The rates are high enough for a primordial eccentricity of any such body to grow to the observed mid-eccentricity range e=0.15-0.7 in the ~few Myr time available during the existence of the protoplanetary disk.
		This planet, however, is likely made eccentric by 16 Cyg A, its distant stellar companion, and hence could have been born on nearly-circular orbit like the rest of bodies in its mass range (Mazeh et al 1997, Holman et al 1997).

		An elliptic orbit is characterized by the eccentricity, which is how much a planet's distance from its star varies as it carves out a year.
		Some have eccentricities of 80 percent, which is as high as the crazy orbits of some comets in our solar system.
		There are many theories for generating — or driving — eccentricities, but the two main ideas are that the planet interacts early on with gaps in the planet-formation disk or later on with another planet.

	DASL - Eccentricity of Earth's Orbit
		Determine the degree of error in your estimate of the eccentricity.
		Eccentricity is a measure of how circular the orbit of a planet or satellite is. For a perfectly circular orbit the eccentricity is zero; elliptical orbits have eccentricities between zero and one.

	Milankovitch Cycles
		Eccentricity is, simply, the shape of the Earth's orbit around the Sun.
		At present the orbital eccentricity is nearly at the minimum of its cycle.
		Axial tilt, the second of the three Milankovitch Cycles, is the inclination of the Earth's axis in relation to its plane of orbit around the Sun.

		When the orbit is highly elliptical, the amount of insolation received at perihelion would be on the order of 20 to 30 percent greater than at aphelion, resulting in a substantially different climate from what we experience today.
		As the orbit gets more eccentric (oval) the difference between the distance from the Sun to the Earth at perihelion (closest approach) and aphelion (furthest away) becomes greater and greater.
		Even the maximum eccentricity of the Earth's orbit—0.07—it would be impossible to show at the resolution of a web page.

	SurfWax: News, Reviews and Articles On Eccentricity
		From these measurements you can calculate the orbital period of the planet and the eccentricity (which indicates if the orbit is circular or elliptical) and estimate further properties of the planet such as its orbital distance and mass.
		She says a few objects could "trade off" some of their elongation, or eccentricity, for a higher tilt, but the effect would be small.
		But the specifics of the model bear attention: The disaster zones are governed by the giant planet's mass and the eccentricity of its orbit, or how noncircular it is. "The larger its orbital eccentricity, the greater the gravitational reach of the giant," said Barrie Jones, an astronomy professor at the Open University in Britain.
