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)


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.


Which planet has the perfect circular orbit?

No planet has a perfectly circular orbit, though Venus has the least orbital eccentricity of any planet in our solar system.


Planet with the least circular orbit?

The eccentricity value measures how non-circular an orbit is. The planets in decreasing order of eccentricity with their approximate eccentricity values are: # Pluto: 0.25 # Mercury: 0.21 # Mars: 0.093 # Saturn: 0.056 # Jupiter: 0.048 # Uranus: 0.047 # Earth: 0.017 # Neptune: 0.0086 # Venus: 0.0068


What planet has the most elongated orbit?

What you are referring to is the eccentricity of the planet's orbit around the sun. Eccentricity of a circular orbit is 0.0, whereas the eccentricity of an extremely elongated orbit is 1.0. So the closer the eccentricity of a planet's orbit is to 1.0, the more elongated is its orbit around the sun. Many extra solar planets have high eccentricities in accordance with their parent stars. In our solar system Mercury ( .20563) and Pluto (.24880766) have the highest eccentric orbits.

What is the eccentricity of asteroids?

it is how circular and asteroids orbit path is.


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"


Does the moon revolve around earth in a circular orbit?

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


What is the compression of the earths orbit around the sun?

The Earth's orbit is almost circular. Technically, the "eccentricity" of the orbit is about 0.0167.

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.


The amount by which an orbit departs from being circular is called its?

It is called eccentricity, literally: off-center.
