WebJan 25, 2024 · Earth's orbit around the sun is more of an oval instead of a circle. The degree of a planet's orbital ellipse is referred to as its eccentricity. This image shows an orbit with an eccentricity of 0.5. earing hooks for making earingsThe eccentricity of Earth's orbit is currently about 0.0167; its orbit is nearly circular. Venus and Neptune have even lower eccentricities. Over hundreds of thousands of years, the eccentricity of the Earth's orbit varies from nearly 0.0034 to almost 0.058 as a result of gravitational attractions among the planets.
