Of the eight planets in the solar system, the one with the most elliptical orbit is Mercury.
To determine which of the eight planets in the solar system has the most elliptical orbit, we can look at their eccentricities. The eccentricity of an orbit is a measure of how stretched out or elongated it is. The closer the eccentricity value is to 1, the more elliptical the orbit is.
To find the eccentricities of the planets, we can refer to reliable scientific sources or use online resources such as NASA's website or other reputable astronomy sources.
Here are the eccentricities of the four planets you mentioned:
- Venus: Eccentricity = 0.0067
- Earth: Eccentricity = 0.0167
- Mars: Eccentricity = 0.0935
- Mercury: Eccentricity = 0.2056
Comparing these values, we can see that the planet with the highest eccentricity (and therefore the most elliptical orbit) is Mercury, with an eccentricity of 0.2056. So, among the four planets mentioned, Mercury has the most elliptical orbit.
