Answer:
Venus - has the most circular orbit .
Explanation:
Eccentricity -
Eccentricity is used to define the circularity of an object .
Lesser the value of eccentricity of the orbit , more circular will be its orbit
and ,
More the value of eccentricity of the orbit , less circular will be its orbit .
In case , the value of eccentricity is zero , the orbit will be a perfect circle.
Hence ,
by considering the eccentricity value of the following plants as -
Venus 0.007
Earth 0.017
Mercury 0.206
Pluto 0.248
Venus has the most circular orbit , as it has the minimum eccentricity value , i.e. , 0.007.
