The orbit is notably elliptical (non-circular), with average distance between the two stars of about 11 Astronomical Units, or Earth - sun distances.

After undertaking many computer simulations lasting 30 theoretical years of 365 days (with the GENESIS2 model), however, astronomer Darren Williams, paleoclimatologist David Pollard, and their colleagues at Pennsylvania State University at Erie have come to believe that Earth could support life even in highly elliptical orbits (0.3 > e > 0.7).

First, variations in the shape of the earth's orbit (more versus less elliptical), the axial tilt, and the direction of that tilt with respect to perhelion all combine to affect the relative seasonal insolation for the northern and southern hemispheres.

Well, this 100 000 year cycle is the ECCENTRICITY CYCLE of the Earth Orbit around the Sun: The orbit oscillates between a more elliptical and a more circular orbit every (approximately) 100 000 yOrbit around the Sun: The orbit oscillates between a more elliptical and a more circular orbit every (approximately) 100 000 yorbit oscillates between a more elliptical and a more circular orbit every (approximately) 100 000 yorbit every (approximately) 100 000 years.

I think that the observed length of day is more real than the lod measured by radio telescopes using distant quasars, the fact that the Earths orbit is elliptical and that the Earth is inclined to the rotation gives us real changes here on Earth (just because something is more accurate does not mean more relevant).

@PP: Jupiter has a small effect on the Earth orbit as it makes the eccentricity vary a little, but the orbit of the Earth remains nearly elliptical relative to the Sun.

This theory stipulates that changes in Earth's elliptical orbit around the sun (eccentricity), changes in the direction in which our axis points (precession) and changes in the tilt of the earth itself (obliquity)-- known as Milankovitch Cycles — should contribute to changes in climate because of the different amounts of solar insolation received during these chaEarth's elliptical orbit around the sun (eccentricity), changes in the direction in which our axis points (precession) and changes in the tilt of the earth itself (obliquity)-- known as Milankovitch Cycles — should contribute to changes in climate because of the different amounts of solar insolation received during these chaearth itself (obliquity)-- known as Milankovitch Cycles — should contribute to changes in climate because of the different amounts of solar insolation received during these changes.

This is a consequence of Kepler's Law for elliptical orbits whereby Earth travels more slowly during aphelion and hence has longer to accumulate the heat that has been reduced by the greater distance.

As a result of Earth's elliptical orbit, the time between the autumnal equinox and the following vernal equinox (about September 22 to about March 21) is almost one week shorter than the remainder of the year in the Northern Hemisphere.

Those forces and motions are driven by the following: First, the motions of the Earth relative to the Sun: the periodic changes in its elliptical orbit, its rotation about its polar axis, changes in the tilt of that axis, and the precession of that axis.

To the Earth's orbit: The mechanism can be detected by looking at the true trajectory of the Earth's flight path: What escaped the present attention is that this path is not a straight elliptical line around the Sun, but the real trajectory is a WINDING SPIRAL, winding around the mean progressive path.

Models have long suggested that Earth's orbit shifts from circular to elliptical and back again over hundreds of thousands of years, which plays a part in natural climate swings.

This long period is associated with the eccentricity of the Earth's orbit, which oscillates between circular and slightly elliptical.

Planetary gravity forces from the outer 4 planets over 100,000 years gradually change the shape of Earth's orbit from circular, to elliptical along with shorter term changes in the inclination angle and winter precession timing.

As I understand it global temperatures are calculated as anomalies, thus removing seasonal swings, but that Heat Content is not, Now our dear planet has an elliptical orbit and is sometimes closer to the sun that others; sure, the shape of the land and oceans doesn't mean that the amount of incoming solar radiation falling on the oceans follows the Earths orbit, but it should be possible to work out the amount of incoming solar radiation each quarter.

The Earth's orbit grows slowly more and less elliptical, even as the angle of the planet's axial tilt, and the wobble of the poles as the planet spins (much like what you see with a spinning top), also change slightly over thousands of years.
