About 0.055 (plus/minus 40%) right now but that varies over a period of about 9 years.

Does the moon revolve around earth in a circular orbit?

No, the moon's orbit is elliptical with an eccentricity of about 0.55


The planet has an orbital eccentricity most like the moon?

The planet with an orbital eccentricity most similar to the Moon is Mercury. Mercury has a slightly eccentric orbit like the Moon, meaning it deviates from a perfectly circular path. This causes Mercury's distance from the Sun to vary significantly during its orbit.


What 2 planets have the most cicular orbits?

Venus has an eccentricity of 0.00677323 Neptune has an eccentricity of 0.00858587 Triton, a moon of Neptune, orbit is as close to a perfect circle with an eccentricity of 0.000016 The Earth for comparison has an eccentricity of 0.01671022


What moon is more circular Phobos or Deimos?

Deimos is more circular than Phobos. Deimos has a nearly circular shape with an eccentricity of only 0.00033, while Phobos is more elongated with an eccentricity of about 0.0151.


Is the moon's orbit around the sun absolutely straight?

Yes, the moon's orbit is elliptical. It has some eccentricity to it (e = 0.0549). The measure of eccentricity is done to give astronomers an idea of how "out of round" a body's orbit about a center is, and it can vary between e = 0 for a perfect circle (no eccentricity), on out to e = 1 for the longest, skinniest ellipse you can immagine (infinite eccentricity).Further to that correct answer, when the eccentricity is small, as it is for the planets (except Mercury), the orbit is very nearly circular, and the eccentricity measures how far off-centre the Sun is.For example the Earth's orbit has an eccentricity of 1/60 and a radius of 150 million kilometres. The Sun is offset from the centre by 150/60 million km, or 2.5 million km.The maximum diameter of the elliptical orbit is 300 million km, while the minimum diameter is 299.96 million km, so there is virtually no 'squashing' of its circular shape.


What is a the eccentricity of a circle?

Eccentricity is only present in ovals and ellipses. A circle is present. The eccentricity of an oval or ellipse is how linear it is.


What is the name of an object with a eccentricity of zero?
