English: 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.

This graph image could be re-created using
vector graphics as an
SVG file. This has several advantages; see
Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{
vector version available|new image name}}.
It is recommended to name the SVG file “Eccentricity rocky planets.svg”—then the template
Vector version available (or
Vva) does not need the new image name parameter.
This graph image was
uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or
SVG format. If possible, please upload a PNG or SVG version of this image without
compression artifacts, derived from a non-JPEG source (or with existing artifacts
removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for
vectorisation, please tag this image with
{{Convert to SVG}} instead of
{{BadJPEG}}. If not suitable for vectorisation, use
{{Convert to PNG}}. For more information, see
{{BadJPEG}}.
