What orbit has the eccentricity that is closest to 0?
Of the planets in our solar system, Venus has the smallest eccentricity.
What does eccentricity mean to an astronomer?
A bodies eccentricity is a measure of how circular the orbit of that body is. Perfectly circular orbits have the lowest eccentricity, of 0, whereas orbits such as that of the dwarf planet Pluto are more eccentric. When there are multiple large bodies in an orbit, with smaller bodies orbiting multiple of these, the eccentricities of the smaller bodies are quite high.
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 number value for the shape of an objects orbit?
The number value for the shape of an object's orbit is called its eccentricity. It is a measure of how elongated or stretched out the orbit is. A value of 0 represents a perfect circle, while values greater than 0 indicate increasingly elongated elliptical orbits.
What is the name of the geocentric figure which has the minimum eccentricity?
It is called a circle.A circle is an ellipse with zero eccentricity.Incidentally, you probably meant "geometric figure".
What orbit has the eccentricity that is closest to 0?
Of the planets in our solar system, Venus has the smallest eccentricity.
A circular orbit would have an eccentricity of?
It would have an eccentricity of 0.
Do planets orbit around the sun in a perfect circle?
All planets orbit the Sun in an elliptical orbit. An elliptical orbit is defined as having an eccentricity of between 0 and 1. (0 is a circular orbit). Anything over 1 is defined as a hyperbolic orbit.Mercury has the highest eccentricity of .205630 whereas the Earth has a near circular orbit with an eccentricity of 0.0167.Triton, a moon of Neptune has lowest eccentricity with a value as close to 0 as can be measured.
Does the earth have an orbit with a low or high eccentricity?
The Earth has an eccentricity of 0.01671123. Where 0 is a perfect circle, and 1 is a parbola. So by that it has a low eccentricity.
What is the eccentricity of orbit in earth days?
The eccentricity of an orbit is not measured in days. The excentricity is a numeric value between 0 (for a perfect circle) to 1 (for an extremely prolonged elipse).The eccentricity of an orbit is not measured in days.

Which planet's orbit is most nearly circular?
Although all planets have elliptical orbits, Venus has the least eccentric orbit (eccentricity of 0.00677323, where 0 would be circular)
Which planet has an orbit that is closest to a perfect circle?
The earth's orbit is almost a circle, but not quite. It is elliptical, but the difference between the closest and farthest points is less than 4%. This is such a small difference that it would look like a circle to most people. Astronomy books often show misleadingly exagerated elliptical orbits.
What is mercury's orbit of the sun?
its orbit is not perfect circle, but is most eccentric of all planets,having eccentricity of 0.21 eccentricity means,the amount by which its orbit varies from perfect circle. 0 means circle and 1 means parabola. so mercury's eccentricity(0.21) is between circle and parabola, in fact, more closer to circle

Why does the changing distance between earth and sun not affect the seasons?
When Earth orbits the sun, its eccentricity of the orbit is only 0.017. That's very close to 0, a perfect circle. So when it's at its closest to the sun (perihelion) , it doesn't make a difference.
What is the eccentricity of Venus?
The eccentricity of Venus' orbit around the Sun is approximately 0.0067. This value indicates how elliptical the orbit is, with 0 being a perfect circle and 1 being highly elongated. Venus has one of the least eccentric orbits among the planets in our solar system.
To moves around the sun in nearly circular path?
Any satellite circling another object is considered to be 'orbiting' that object in a circular orbit.Wikipedia made the following statement, under topic, "circular orbit":"In astrodynamics or celestial mechanics a circular orbitis an elliptic orbit with the eccentricity equal to 0."Here, the 'eccentricity' would be referring to the degree to which the orbit moves outside that of forming a perfect cirular path. As a circular path would have no variance from being circular, of course, it has no "eccentricity/ies"
