Elliptical Ratio

The Elliptical Ratio property of an elliptical galaxy is a measure of how much the galaxy's shape varies from perfectly spherical. The Elliptical Ratio is the ratio of the length of the shortest axis of the galaxy to the length of the longest axis of the galaxy. For example, if the galaxy's length is twice its height, the Elliptical Ratio is 0.5. A perfectly spherical galaxy will have an Elliptical Ratio of one.

Location
The Elliptical Ratio property is located in the Elliptical section of the Galaxy tab of the galaxy's properties page. This section is only visible for elliptical galaxies.
