and gentle nod, affording observers fleeting glimpses of its northern and southern poles. likewise, the eccentricity of the moon's orbit lends its face a slight wag, enabling those of us on earth to peer over its eastern and western edges as it swishes back and forth, not unlike the :...
Eccentricity Change in the shape of Earth's orbit is called eccentricity. This change could also affect the climate in different parts of the world over a long period of time. Axial Procession of the Equinoxes Bulges in the spherical shape of Earth causes the planet to wobble on its axial ...
Of all the planets in the Solar System, Neptune orbits the Sun at the greatest average distance. With a very minor eccentricity (0.0086), itorbits the Sun at an semi-major axis of approximately30.11 AU(4,504,450,000,000 km), ranging from29.81 AU(4.459 x 109km) at perihelion and30.33 ...
As one moves outward from the sun to each planet's orbit, the successive distance between neighboring planets grows increasingly large. The Earth's average distance of 93 million miles is called one astronomical unit, or AU. When comparing the distance between planets, it is useful to scale th...
Milankovitch cycles play a long term role in fluctuations in climate on the Earth. This is the result of changes in the eccentricity, obliquity and precession of the Earth’s axis and orbit. For example, perihelion, or our closest point to the Sun, currently falls in January in the middle...
Orbits of natural bodies in the universe are usually not perfectly circular — they are elliptical. Some orbits are ever so slightly elliptical (like a somewhat squashed circle, or, in astronomical terms, an orbit with low eccentricity), whilst some appear rather flattened (highly eccentric orbits...
The amount of sunlight that reaches the outer atmosphere of our planet depends on three parameters: the tilt of Earth's axis toward the plane in which the planet orbits, the eccentricity of its orbit (how elliptical the orbit is), and the so-called precession of the planet's axis (as Ea...

Orbit and Distance: With an average distance (semi-major axis) of4,504,450,000 km(2,798,935,466.87 mi or 30.11 AU), Neptune is the farthest planet from the Sun. The planet has a very minor eccentricity of0.0086, which means that its orbit around the Sun varies from a distance of29.8...
