To determine which of the eight planets in the solar system has the most elliptical orbit, you can consult the orbital eccentricity of each planet. Orbital eccentricity is a measure of how elongated an orbit is, with a value of 0 representing a perfect circle and a value close to 1 representing a highly elliptical orbit.
Here are the orbital eccentricities of the four planets you mentioned:
Venus: 0.0068
Earth: 0.0167
Mars: 0.0934
Mercury: 0.2056
From these values, it is apparent that Mercury has the highest orbital eccentricity. Therefore, Mercury has the most elliptical orbit among the four mentioned planets.
