WebChanges in the orbit. Mars is in the midst of a long-term increase in eccentricity. It reached a minimum of 0.079 about 19 millennia ago, and will peak at about 0.105 after about 24 millennia from now (and with perihelion distances a mere 1.3621 astronomical units).The orbit is at times near circular: it was 0.002 1.35 million years ago, and will reach a similar … In modern times, Earth's perihelion occurs around January 3, and the aphelion around July 4. In other words, the Earth is closer to the Sun in January, and further away in July, which might seem counter-intuitive to those residing in the northern hemisphere, where it is colder when the Earth is closest to the … See more Earth's orbit is an ellipse with the Earth-Sun barycenter as one focus and a current eccentricity of 0.0167.
