Description: Gravity Simulator plot of the changing orbital eccentricity of Mercury, Venus, Earth, and Mars over the next 50,000 years. The 0 point on this plot is 2007-02-01. On going perturbations of the planets by other planets cause small variations in the Kepler orbits. Venus currently has the most circular orbit of the planets, but in 25,000 years Earth will have a more circular (less eccentric) orbit than Venus. Note were the arrows point as the the Y axis uses two different scales.
