Question

Which of the four inner planets has the least eccentric orbit around the sun

Answer 1

Among the four inner planets of the solar system—Mercury, Venus, Earth, and Mars—Venus has the least eccentric orbit. The eccentricity of an orbit quantifies how much it deviates from being circular, with a value of 0 representing a perfect circle. Venus has an eccentricity of about 0.007, making its orbit very close to circular compared to the other inner planets.
