Orbital mechanics is a branch of planetary physics that uses observations and theories to examine the Earth's elliptical … WebThe eccentricity of Earth's orbit is currently about 0.016 7; 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 0.003 4 to almost 0.058 as a result of gravitational attractions among the planets. [3]
