Variable, as an ellipse is not a perfect circle.

∙ 13y agoThat's a bit tricky. Each type of galaxy has a wide range of sizes, so you can't say, for example, that any elliptical galaxy is larger than any spiral galaxy - because they aren't - though I believe that elliptical galaxies do have a general tendency to be larger than the other types.
Yes. Although if you are measuring the diameter of an atom, or a galaxy, you might consider other units to be far more suitable.
Elliptical galaxies have an oval shape. An example is the Messier 87.
Circumference of a circle is pi * diameter. Diameter is 2 * radius. So if you know the radius, circumference is 2 * pi * radius. Now choose an appropriate approximation for pi (3.14, or 3.1416, or even the fraction 22/7), depending on your application. This will work for ANY circle, no matter how big or small it is, as long as it's a true circle and not a different elliptical shape, e.g. an oval.
The cart is before the horse. Before an example can be cited, we need a definition of elliptical energy. Come back when you have that.
No, an EO galaxy is not a type of elliptical galaxy. They are a lenticular galaxy.
We live in a spiral galaxy, not in an elliptical galaxy.
An elliptical galaxy is a type of galaxy not a particular one.
An elliptical galaxy is an egg shaped galaxy that has an almost featureless image.
The largest known galaxy is elliptical
No. The Milky Way is believed to be a barred spiral galaxy.
An elliptical galaxy is round. A spiral galaxy is shaped like a spiral.
Elliptical Galaxy The Elliptical Galaxy has mostly old stars and blue stars are new stars.
The Andromeda Galaxy is a spiral galaxy.
An elliptical galaxy.
BL Lacertae is the active center of an elliptical galaxy.
An elliptical galaxy is a galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile. The galaxies range in shape from nearly spherical to highly flattened and have hundreds of millions to over one trillion stars.See link for more information
